    Wewum reacted to Bavor for an article, World of Tanks 9.14 GPU comparison   
    Introduction:
    For how popular of a game as World of Tanks is, I haven't seen many benchmarks comparing different graphics cards/GPUs to the game performance.  You might see one popping up every year or two with limited info about testing methods.  When I read that 9.14 was going to move the sound processing to another CPU core, I decided that after 9.14 was released, it would be a good time to compare different GPUs.  I'm going through the process of using different GPUs with the same replays to compare their performance.
    For smooth game play you want to keep your minimum FPS(Frames per Second) above 30 FPS.  Games can start looking like a slide show below 30 FPS.  Games tend to look smoother and are easier to play when you keep your minimum frame rates higher.  Generally 50-60 FPS is where games start to look much smoother to most gamers.  Some people with 60 Hz monitors prefer to have their minimum FPS never drop below 60 FPS then enable V-sync to reduce the visual effect called screen tearing.  Other players have monitors that are capable of 75, 100, 120, or 144 Hz refresh rates and want higher average FPS in game.  Minimum and average frame per second are a matter of both game play quality and personal preference and can be limited by the hardware.  Maximum FPS isn't as important for game play as minimum FPS and average FPS.
    There is a myth that the human eye can't distinguish any difference above 30 frames per second, so that having more than 30 FPS is useless.  In scientific testing, it has been proven that the human eye may be able to see differences in frame rate at over 200 frames per second.  Other tests have shown that computer gamers can see a difference between 30 frames per second, 60 frames per second, and 100+ frames per second while playing computer games on newer monitors that have the capability of using refresh rates above 100 Hz.  Also, some people say that television and movies are shown at approximately 30 FPS, so more than 30 FPS isn't necessary.  However movies and television shows often use motion blur to hide what would seem to be jerky movement due to being played at 30 FPS.
    Another advantage of higher frame rates is less input lag and less game lag.  You may have a great ping and no packet loss, but if you are averaging 30 FPS it may feel that you have higher ping when you play because there is more lag in the game itself.  For example, if you play at 30 FPS, each frame is about 0.0333 seconds.  If you play at 60 FPS, each frame is 0.0167 seconds.  If you play at 100 FPS, each frame is 0.0100 seconds.  To many players, having higher frame rates feels and acts like having a better in game ping.  Some players feel that higher FPS in a game makes it easier to hit moving targets in game and to hit smaller targets in game.
     
    Methods:
    Replays:
    I downloaded quite a few replays from WoTReplays.com and found a few to find what I was looking for. I ended up using three different replays that I downloaded from WoTReplays.com.  Two replays were used more than the third replay.  The first replay is a Comet on Serene Coast. Link: http://wotreplays.com/site/2546813  The second replay is a Type 64 on Abbey. Link: http://wotreplays.com/site/2536214 The third replay is an IS-6 on Kharkov Link: http://wotreplays.com/site/2544611.  I used the Comet replay because a large part of the battle occurs near the water, has tanks driving through water, and it is a good replay to see how the water quality settings affect game performance.  The Type 64 replay was used because it has a wide variety of game play events, game environments, and was stressful to even higher end GPUs giving the lowest average frames per second and lowest minimum frames per second of all the different replays I tried.  I also used the IS-6 replay because I wanted to see how stressful on the graphics heavy tank play is around buildings.  It ended up that heavy tank play in the city is not very stressful on the GPU for most mid and high end GPUs.  Several other replays of heavy tank play on city maps showed that it seems to be less stressful and yielded higher FPS than other types of replays.  The IS-6 replay is more of a best case scenario instead of an average or demanding replay.  Because of this I didn't use the IS-6 replay to test many of the GPUs.
     
    Computer systems used:
    Desktop:
    i7 3770K overclocked to 4.4 GHz and water cooled.
    32 GB RAM (8GB x 4 sticks)
    1 TB Samsung EVO 850 SSD
    Seasonic 650 Watt power supply
    Windows 10 Pro
    The overclocked i7-3770K was used to reduce any limitations of the CPU performance in frame rates of the replays.  Also the 3770K allows adjustment of CPU speed to see what effect CPU speed has on frame rate.
    Graphics cards tested in the Desktop and their manufacturer's part numbers:
    GTX 970* (04G-P4-3979-KB)
    GTX 960 (02G-P4-2968-KR)
    GTX 660 ti (02G-P4-3664-KR)
    GTX 750 ti (02G-P4-3751-KR)

    R7 260 (GV-R736OC-2GD)
    8800 GTS 512MB (512-P3-N841-A3 512MB)
    Intel's HD 4000 integrated graphics on the i7 processor
    *The GTX 970 was borrowed and returned to its owner.  Testing time was limited.
    The Nvidia GPUs were all tested with driver version 364.51 except for the 8800 GTS 512 which was tested with the latest driver for that GPU which is version 341.92
    Laptop:
    MSI GT60
    i7-3630QM
    GeForce GTX 680M 4GB DDR5
    12 GB RAM
    500 GB Samsung 840 SSD
    Windows 10
    I used the Fraps program to record minimum, maximum, and average FPS.  Each replay was measured by FRAPS for 3 minutes and 30 seconds.  Measurement of the frames per second started when the countdown timer reached 00:00.  The replays were measured three times in a row and the averages of the three replays with the same settings were used.  Each replay was run three times to be sure there were no unusual reading of the FPS measurements and to ensure consistent and accurate results.  No game mods were installed for the test.  The results were very consistent for most of the GPUs with the usual variation of average and minimum FPS being 1 FPS or less.  I noticed when comparing to previous tests of GPUs I performed using FRAPS and replays on the GTX 680M and the 8800 GTS 512MB that the minimum FPS results were less consistent in patch 9.14 than they were in patch 9.13 and earlier.  However the minimum FPS rarely varied more than 3 FPS on the GTX 680M and 8800 GTS 512MB when running the same replay three times in a row or when running the same replay on different days to see if I'd get the same results.
    To do testing on your own computer, you can purchase Fraps here: Fraps Web Page
    In addition to the effect of different GPUs on frame rate, different graphics options and different CPU speeds were tested for their effect on frame rate to determine what options have the highest effect on frame rate.
     
    Test Results:
    Effect of CPU speed on FPS:
    Even though sound processing was moved to another core, World of Tanks still depends on single threaded performance to determine FPS.  However, less of the CPU's single threaded performance is used for sound.  I tested WoT at "Full Maximum" graphics and varied the CPU speed.

    As you can see, there is a point where increasing the CPU speed doesn't yield much better frame rates.  This is most likely the limit of the graphics card if increasing the CPU speed doesn't have a significant increase in FPS.  I'll be doing further testing with other GPUs to determine if the CPU speed that no longer makes a difference is FPS is similar or if it varies on different GPUs.  On lower graphics settings there is also an issue where the average FPS and minimum FPS seem to vary little between GPUs because many of the GPUs spend a large part of time at the game maximum of 120 FPS.
    Effect of Nvidia PhysX on FPS:
    The Bigworld Game engine is listed as one of the game engines that support Nvidia PhysX.  I've seen players ask, "When I upgrade my video card, should I save my old one and use it for a dedicated PhysX card for World of Tanks?"  I put the GTX 750 ti in the second PCI Express 3.0 x16 slot in my motherboard and went into the Nvidia Control Panel and set the GTX 750 ti as a dedicated PhysX card.  Then I reran the benchmarks for the GTX 960 on the Abbey and Serene Coast replays.  The results are below.

    You can see there was no significant improvement in minimum or average frame rate by using a second Nvidia GPU as a dedicated PhysX card.  It looked liek the average FPS was actually slightly higher in both replays by not having a dedicated PhysX GPU.  However, the slightly higher frame rate is well within the margin of error.  If you are interested in more detailed FPS info with the Type 64 replay on the Abbey map, you can click the link below.
    More detailed info PhysX vs No PhysX.
    In summary, it looks like World of Tanks does not benefit from a dedicated Nvidia PhysX GPU.
     
    Full Maximum Graphics Benchmarks:
    The in game "Maximum" graphics setting does not turn all the graphics sliders all the way up.  Also, the in game "Maximum" graphics setting does not enable AA.  For the first benchmark comparison, I turned all the sliders all the way up, enabled TSAA-HQ, set the FOV to 95 degrees, set 3D Render Resolution to 100%, and turned off Dynamic Adjustment and Dynamic Changes of Effects.  This increases graphics and effects quality and is more demanding on the GPU than the in game "Maximum" setting.  Screenshots of the settings used are below.



     
    Results of the currently tested GPUs at 1920x1080 resolution and full maximum graphics:

    At 1920x1080 resolution, all the the GPUs tested with full maximum graphics settings used between 1.7 GB and 1.9 GB of graphics memory according to MSI Afterburner.  The 4 GB memory GPUs did not use more than 1.9 GB of graphics memory at either resolution.  MSI Afterburner was run separately to the FPS benchmark tests to see the graphics memory used.
    GTX 970: For players who don't want their FPS to drop below 60 FPS in game at 1920x1080 resolution at this graphics setting, the GTX 970 works very well.  It was the only GPU tested that was able to maintain a minimum FPS greater than 60.  Because of the high minimum and average FPS the GTX 970 is capable of, it offers very smooth game play at this graphics setting.  You can see that the GTX 960 did similar in minimum frame rates as the GTX 970.  However the GTX 970 had much higher average frame rates at this graphics setting.  The GTX 970 Graphics cards with similar specs to the one used here currently sell for $295-$380 in the US market.
    GTX 960: If you play with V-sync enabled on a 60Hz refresh rate monitor and no game mods or minimal game mods, the GTX 960 will be adequate for most game situations at 1920x1080 resolution with this graphics setting and offer very smooth game play.  The GTX 960 costs over $100 less than the GTX 970 at current US market prices and has a minimum FPS that is only slightly below 60 FPS.  The GTX 960's with similar specs to the one used here sell for $165-$185 in the US market.  One thing to consider with the GTX 960 is if you play other games that require more graphics memory, a GTX 960 with 4 GB of graphics memory and similar GPU speed to the one tested here currently sell for $185-210 in the US market.
    GTX 660 ti: Considering that the GTX 660 ti is a GPU released in the summer of 2012, its performance is still very good in World of Tanks.  With an average FPS greater than 60 and a minimum frame rate slightly less than 50 FPS the GTX 660 ti can offer smooth game play at this graphics setting.  Also, fully functional GTX 660 ti graphics cards are selling for $65-100 on eBay in the US depending on the model and included accessories.  The GTX 660 ti s a very good deal for World of Tanks if you have under $100 to spend on a graphics card.  However, a four year old, used GPU usually doesn't have a warranty if that is a concern to you.
    R7 370: The R7 370 couldn't hit an average of 60 FPS in game at these settings.  However, the minimum FPS stayed above 40 which would allow for mostly smooth game play at this graphics setting without game mods installed.  The R7 370 I used was a factory overclocked model and is one of the highest overclocked R7 370 graphics cards on the market at 1050 MHz. There are a few R7 360 models with slightly higher clock speeds available.  I tried this R7 370 overclocked to 1100 MHz and the FPS results were almost the same as the factory overclock of 1050 MHz.  The factory overclocked R7 370 models with similar speeds all currently sell for $125 to $160 in the US market.
    GTX 750 ti: The GTX 750 ti was able to maintain a minimum of over 30 FPS at this graphics setting.  While the game play wouldn't be as smooth as a GPU capable of 60 FPS minimum, the game is playable if the minimum FPS doesn't drop below 30 FPS.  I could see a difference between the GTX 750 ti and the GTX 960 while playing the game with both GPUs back to back.  If you install game mods, your minimum FPS will likely be below 30 FPS and that will be noticeable.  The GTX 750 ti used in this test is a model that uses power from the PCI Express x16 slot.  It does not require external power.  You can buy half height GTX 750 ti video cards that can be used in slim and small form factor computers.  There are faster GTX 750 ti models that use a 6 pin external power connector and are overclocked well above factory specs.  I did not have one available for testing.  The overclocked GTX 750 ti graphics cards that require 6 pin external power currently sell for about $130 in the US.  At $130 you can buy a video card with a faster GPU.  The GTX 750 ti graphics cards that don't require external power sell for $95-$110 in the US market at this time.
    GTX 680M: The GTX 680M is a mobile GPU that was released in the summer of 2012.  The GTX 680M on the laptop still maintained a minimum FPS of about 30.  This allowed for the game play to be smooth, but I could see a difference between the GTX 680M and the GTX 960 while playing the game.  If you install mods, the GTX 680M will most likely need lower graphics settings to maintain a minimum of 30 FPS in game.  The GTX 750 ti and GTX 680M offered similar performance with the GTX 750 ti having a slightly higher minimum frame rate while the GTX 680M had a slightly higher average frame rate at this graphics setting.  Both the GTX 680M and GTX 750 ti use different methods of achieving similar results.  The GTX 750 ti relies on faster clock speeds, while the GTX 680M relies on a higher throughput due to more processing cores.
    R7 360: The R7 360 couldn't maintain a minimum of 30 FPS and struggles to maintain 25 FPS at this graphics setting.  During the replay and while playing the game with the R7 360, the game didn't appear to be smooth in many occasions.  I noticed instances of the slide show effect and my mouse movements making the aim point move where I didn't want it to be.  I wouldn't recommend the R7 360 at this graphics setting for smooth game play.  The R7 360 graphics cards sell for $90-$130 in the US at this time.
    If you are playing World of Tanks without mods or maybe with minimal mods and using the "Full Maximum" setting described above, the two GPUs that will allow for truly smooth game play are the GTX 860 and GTX 970.  The GTX 660 ti is a close runner up with an average FPS of almost 64 FPS.  The R7 370, GTX 750 ti, and GTX 680M were playable and maintained above 30 FPS.  I would not recommend the R7 360 at this graphics setting.  If you only had $100 to spend on a graphics card for World of Tanks and were not interested in buying a used graphics card, I'd recommend the GTX 750 ti over the R7 360 based on the results of these tests..
     
    Maximum Graphics Benchmarks:
    The game preset "Maximum" was selected.  Other setting included, AA was turned off, FoV was set to 95 degrees, set 3D Render Resolution to 100%, and turned off Dynamic Adjustment and Dynamic Changes of Effects.  No game mods were installed.
    Results of the tested GPUs at 1920x1080 resolution and maximum graphics:

    GTX 970: For players who don't want their FPS to drop below 60 FPS in game at 1920x1080 resolution at this graphics setting, the GTX 970 works very well.  The GTX 970 averaged over 100 FPS and its minimum frame rate was slightly below 70 FPS at the Maximum graphics setting.  The GTX 970 will likely keep the minimum frame rate above 60 FPS with a few minor mods installed such as XVM and cross hair.
    GTX 960: The GTX 960 offered a minimum frame rate that was only slightly below that of the GTX 970.  However its average frame rate was slightly above 90 FOS instead of 100 FPS.  The GTX 960 has more than enough performance for playing World of Tanks with no mods if you want to never drop below 60 FPS.  At this graphics setting the GTX 960 might even keep the minimum FPS around or above 60 FPS with a few game mods installed such as a basic XVM config and cross hair.
    GTX 660 ti: The GTX 660 ti continued to perform well for an older GPU.  At this graphics setting the average frame rate was above 70 FPS and the minimum framerate was 55 FPS.  Overall, this GPU is capable of keeping the FPS above 60 most of the time, so that playing with V-sync enabled and not dropping below 60 FPS often is possible.
    R7 370: The R7 370 performed similar to the GTX 660 ti at this graphics setting.  The average FPS was slightly higher than the GXT 660 ti.  However, the minimum FPS of the R7 370 was lower than the GTX 660 ti.  This is another GPU is capable of keeping the FPS above 60 most of the time, so that playing with V-sync enabled and not dropping below 60 FPS often is possible.
    GTX 680M: The GTX 680M continued to perform well for an older mobile GPU.  The average frame rate was just below 60 FPS and the minimum frame rate was above 40 FPS.  Overall game play was smooth with this GPU.  Installing game mods might bring the minimum frame rate close to 30 fps depending on what game mods you install.  Adding XVM and cross hair might allow the minimum frame rate to stay above 30 FPS.
    GTX 750 ti: The GTX 750 ti was still smooth and playable at this graphics setting.  The average frame rate was 55 FPS and the minimum frame rate was a little below 40 FPS.  Just like the GTX 680M, installing game mods might bring the minimum frame rate close to or below 30 FPS depending on what game mods you install.  Adding XVM and cross hair might allow the minimum frame rate to stay above 30 FPS.
    R7 360: The R7 360 managed an average frame rate just above 50 FPS and barely managed to keep the minimum frame rate above 30 FPS at this graphics setting.  Installing mods and using this graphics setting will make the minimum frame rate drop below 30 FPS and have an effect on game play.
    Based on the results above, both the GTX 970 and GTX 960 work well for a player who wants to keep the minimum frame rate above 60 FPS.  The GTX 660 ti and R7 370 also both worked well for players wanting smooth game play with their minimum frame rates being around 55 FPS.  The GTX 660 ti continued to be a good value for a used GPU for World of Tanks.  Again, I'd recommend the GTX 750 ti over the R7 360 if you only had $100 to spend on a new GPU for World of Tanks.
     
    High Graphics Benchmarks:
    The game preset "High" was selected.  Other setting included, AA was turned off, FoV was set to 95 degrees, set 3D Render Resolution to 100%, and turned off Dynamic Adjustment and Dynamic Changes of Effects.  No game mods were installed.
    Results of the tested GPUs at 1920x1080 resolution and High graphics:

    With the graphics at the "High" preset, the GTX 970, GTX 960, GTX 660 ti, and R7 370 all were able to keep a minimum FPS above 60 FPS at 1920x1080 resolution.  If maintaining a minimum of 60 FPS at 1920x1080 resolution is important to you, then all three of these cards will get that done as long as you don't play with game mods installed.  Even on the "High" graphics setting we are starting to see similar minimum FPS and average FPS results from several GPUs. Both the GTX 970 and GTX 960 were hitting 120 FPS in several areas of the replay. Both the GTX 660 ti and R7 370 were hitting a maximum FPS of just under 120 FPS in several areas of the replay.
    GTX 970: The GTX 970 started to hit the frame rate limit in World of Tanks at this setting with parts of the replay were capped at 120 FPS.  At the High graphs setting, the GTX 970 should be more than capable of maintaining a minimum frame above 60 FPS even with some mods installed.
    GTX 960: The GTX 960 was occasionally hitting the frame rate limit in World of Tanks at this setting.  The minimum frame rate was slightly below that of the GTX 970.  However the average frame rate was about 5 FPS less than the GTX 970.  That might not be an accurate representation of the performance difference between the GTX 970 and GTX 960 because of the GTX 970 being capped at 120 FPS for larger parts of the replay.  The GTX 960 should be able to maintain a minimum of 60 FPS at this graphics setting with soem mods installed.
    GTX 660 ti: The GTX 660 ti again showed itself as being a good value in a used GPU for World of Tanks.  The minimum frame rate was similar to that of the GTX 960.  The GTX 660 ti should be able to maintain a minimum of 60 FPS at this graphics setting with some mods installed.
    R7 370: The R7 370 had a similar average FPS to that of the GTX 660 ti.  However it minimum frame rate was consistently a little lower.  The R7 370 continued to be a good value for a GPU in World of Tanks. The R7 370 should be able to maintain a minimum of 60 FPS at this graphics setting with some mods installed.
    GTX 750 ti: The GTX 750 ti performed well at this graphics setting.  Overall it offered smooth game play with its average frame rate being close to 75 FPS and its minimum frame rate being a little less than 55 FPS.  If you play with no mods installed and want your frame rate to stay above 60 FPS most of the time the GTX 750 ti will do that at this graphics setting.  With mods installed, the average frame rate will probably stay above 60 FPS.
    GTX 680M: The GTX 680M offered smooth game play at this graphics setting and did well for an older mobile GPU.  The average frame rate stayed above 60 FPS and the minimum frame rate was just under 48 FPS which allows for smooth game play.  With some game mods installed the GTX 680M should be easily capable of keeping the minimum frame rate above 30 FPS at this graphics setting.
    R7 360: The R7 360 was able to maintain an average frame rate equal to the GTX 680M.  However, its minimum frame rate was lower than the GTX 680M at 41 FPS.  Overall, game play at this setting should be smooth at this graphics setting.  With some game mods installed the R7 360 should be easily capable of keeping the minimum frame rate above 30 FPS at this graphics setting.  Again, if your budget for a new GPU for World of Tanks is $100, I'd recommend the GTX 750 ti over the R7 360.
     
    Medium Graphics Benchmarks:
    The game preset "Medium" was selected.  Other setting included, AA was turned off, FoV was set to 95 degrees, set 3D Render Resolution to 100%, and turned off Dynamic Adjustment and Dynamic Changes of Effects.  No game mods were installed.  
    Results of the tested GPUs at 1920x1080 resolution and Medium graphics:

    GTX 970: The GTX 970 was not completely tested under the "Medium" graphics setting.  Under the "High" graphics setting, the GTX 970 spend parts of the replays at the game's limit of 120 FPS.  There is a game engine limitation that doesn't allow faster frame rates than 120 FPS in World of Tanks.  Testing the GTX 970 under "Medium" would not yield accurate results because the average FPS would be skewed by the game's limitation of 120 FPS.  One test of both the Type 64 replaya nd Comet replay were done with the GTX 970 at the Medium graphics setting and the Fraps log file showed large parts of the replay's frame rate capped at the game's maximum of 120 FPS. 
    GTX 960 GTX 660 ti R7 370: The GTX 960, GTX 660 ti and R7 370 all ran into the issue where they hit the cap of 120 FPS for portions of the replay using the "Medium" setting.  This caused all three GPUs to yield similar results for average and minimum FPS.  I'm not sure if its due to a CPU limitation or a game engine limitation due to the single threaded nature of the game or a combination of both.  The GTX 960, GTX 660 ti, and R7 370 all have different pixel fill rates and texel fill rates according to benchmarks.  Also, the GTX 960, GTX 660 ti, and R7 370 all give different benchmark result in WoT at other settings and in other games.  Therefore, its probably not a GPU issue limiting the performance on the "Medium" setting.  All of them also offered smooth game play at the "High" setting.  Unless the use of mods decreases your frame rates significantly, I'd suggest using the GTX 960, GTX 660 ti, and R7 370 at the "High" preset.
    GTX 750 ti: The GTX 750 ti maintained a minimum frame rate of almost 73 FPS and an average frame rate of over 95 FPS at this graphics setting.  This allows for very smooth game play and also would allow for some game mods to be installed without the frame rate dropping below 60 FPS.  
    R7 360: The R7 360's minimum frame rate at this graphics setting was 59 FPS.  That's more than adequate for players who want keep a their frame rate of 60 FPS.  The actual amount of time the frame rate would be below 60 FPS is rather low.  Of course installing mods would drop the frame rate below 60 FPS.  Again, I'd recommend the GTX 750 ti over the R7 360 if you only had $100 to spend on a new GPU for World of Tanks.  The difference of 12 FPS in the minimum frame rate between the GTX 750 ti abd R7 360 is a significant difference.
    GTX 680M: The GTX 680M should offer smooth game play at this graphics setting with an average frame rate close to 75 FPS and a minimum frame rate of 50 FPS.  However, the GTX 680M didn't quite have the ability to keep the minimum frame rate close to 60 FPS at this graphics setting.
    8800 GTS 512: The performance og the 8800 GTS 512 at the Medium graphics setting isn't adequate for good game play.  It was definitely noticeable when the frame rate dropped and replay did spend significant portions of the battle below 30 FPS.  If you are using an older GPU, you should either use the Low" graphics setting or play at a lower resolution.
     
    Older GPU in World of Tanks:
    I was able to test World of Tanks with an 8800 GTS 512 and also compare its game performance to the Intel i7 integrated HD 4000 graphics.  The test was conducted at 1920x1080 resolution.

    The 8800 GTS 512 offered poor performance using the in game "Medium" graphics setting at 1920x1080 resolution.  The minimum FPS was consistently 25 FPS and the average FPS was below 40 FPS.  The lack of smoothness was noticed while playing the game.  If you are using an older GPU, I' suggest a resolution much lower than 1920x1080.  
    At the "Low" setting the 8800 GTS 512 was very smooth and playable.  The 8800 GTS 512 made high frame rates in World of Tanks at 1920x1080 resolution on the "Low" setting.

    I tried the 8800 GTS 512 at 1600x900 resolution and achieved a minimum of 35.33 FPS and an average of 49.49 FPS with the Type 64 replay.  This frame rate is playable and won't give you the slide show effect when the frame rate drops below 30 FPS that will happen with this GPU at higher resolutions.  With older/slower GPUs I'd recommend lower resolution settings if you don't want to use the "Low" or "Minimum" graphics.
    The 8800 GTS 512 is a GPU that was released in December 2007 and has 512 MB of video RAM.  I was curious if it offered better performance in World of Tanks than the integrated HD 4000 graphics on the i7 processor on the in game "Low" setting.

    As you can see at the in game "Low" setting an older GPU is still an improvement over the Intel HD 4000 integrated graphics.
    Effect of Graphics Options on FPS:
    Using the "Full Maximum" graphics option explained above, the graphics settings were tested with them being turned down to "Low" or "Off" to see if they had a significant change in frame rate.  Most fo the settings had a minimal effect on minimum or average FPS in the game.  However there were a few setting that when turned to "Low" or "Off" had a significant effect on frame rate across multiple GPUs.

    As you can see, turning shadows off consistently improved FPS among many different GPUs.  Turning Lighting off also significantly improved FPS on most GPUs.  For some unusual reason turning lighting off actually decreased the minimum FPS on the GTX 970 while increasing the average FPS.  This was verified after the computer was rebooted and the replay's FPS was measured again with both the "Full Max" baseline settings and Lighting "Off" in graphics options..  Turning off Extra Effects Off in both regular mode and sniper mode had a significant improvement on FPS.  Turning off Anti-aliasing (TSAA-HQ) improved the FPS on less powerful GPUs the most.  On the GTX 970 and GTX 960, turning AA off didn't change minimum FPS.
    In testing the replay with the Comet on Serene Coast, turning the water quality to "Low" resulted in a 0 to 3 FPS improvement in minimum FPS and average FPS over water quality being set to "maximum" on all the GPUs tested.
     
    Using other benchmarks to predict World of Tanks GPU performance:
    As an experiment, I ran each GPU through a series of benchmarks after the World of Tanks FPS testing with each GPU to see if there was a correlation with any other benchmark and World of Tanks performance.  I tried the following benchmarks to see if there was a good correlation between performance in those benchmarks and World of Tanks average FPS or minimum FPS.
    Passmark 3D GPU benchmark 3DMark Fire Strike 3DMark Sky Diver 3DMark Cloud Gate 3DMark 3D Mark 11 3DMark 3D Vantage 3DMark 3D Vantage Extreme Texel Fill Pixel Fill There was no strong correlation between relative performance in those benchmarks and relative performance in minimum FPS or average FPS in World of Tanks 9.14.  Unfortunately, you can use other benchmarks of GPU performance to estimate World of Tanks FPS performance of different GPUs.
     
    Conclusion:
    Using the different graphics settings can vastly improve game play performance in World of Tanks.  You can customize the settings on most newer graphics cards, including ones that cost about $100 new, to achieve smooth game play.  Overall, the faster the GPU, the higher the FPS will be in World of Tanks.  However, you don't need to spend $600 on a GTX 980 ti for World of Tanks to get good performance in this game.  Even a GPU form 2007 will play World of Tanks on Low settings or lower resolutions very well and integrated graphics on some newer CPUs will play World of Tanks at a playable level.  If you play games other than World of Tanks, take a graphics card's performance in those other games into consideration in addition to World of tanks performance.
    Notes:
    I received no free hardware for testing or evaluation from any retailer or manufacturer of computer hardware for this comparison test.  I previously purchased Fraps to test other games.  I owned some of the GPUs used in the test, borrowed the GTX 970(and paid for overnight shipping to send it back to its owner), and purchased a few other GPUs for testing when I found them on sale for below average prices(Used, demo models sitting in a display case at a hardware shop, last one in inventory, etc...).  I will be buying other GPUs to add to testing of World of Tanks version 9.15.

    Wewum reacted to Folterknecht for an article, The GW-E100   
    The G.W.E100
     

     
     
     
    The GW-E100 is based on the chassis of the E-100. The E-Series was an attempt to standardize the German tank production late in the war. The goal was to create an easier and cheaper to produce line of vehicles for different purposes. The GW-E100 never reached the prototype stage.
     
     
    The GW-E100 has the following main properties which also greatly influence skills and equipment:
    Worst mobility of all tier 10 artillery (but not by much since the arty nerf in 0.8.6) Good amount of HE damage per hit (3rd place amongst the other t10 artillery) Mediocre accuracy Can absorb more HE damage than any other t10 SPGs (not sure about British CGC though) The G.W.E100 is more or less a jack of all trades but only achieves the top scores when it comes to ramming enemies, something nobody is really interested in when playing artillery. The accuracy is good enough to hit quite consistently (0.84 and 7sec aim-time) and the splash radius is also ok, which allows you to damage tanks hiding behind cover. A hitrate of 40% is possible with this SPG, but in every discipline you will find artillery pieces that perform better.
     
    Before we can spread our love in form of 21cm HE presents on the battlefields, we have to outfit this juggernaut with the right equipment and teach the crew some tricks. Useful mods will also be mentioned.
     
    Equipment and consumables for the GW-E100
     
    To increase the mobility and overall performance of your G.W.E100 play with chocolate. It increases overall crew performance by 10% including accuracy, aim-time and mobility.
     
    The choices for equipment on artillery in general are quite clear: Enhanced gun laying drive for faster aiming and rammer for faster reload. Now you may ask optics - WTF? The one who spots first, will shoot first or can run for cover ... and sometimes it even happens that artillery has to scout. In the second half of the match some tanks are also driving around with a dead commander. With BIA, optics, chocolate, recon and situational awareness the G.W.E100 reaches ~447m viewrange.
     
    Furthermore camo on many SPG's tier 7 and above it's mostly useless (see camo values below). This SPG has a camo value nearly as bad as the Maus, so there is absolutely no sense in wasting a slot for a camo net (every hull movement negates the effect by the way), and if you 're spotted, your team f***** it up in most cases.
     
    Camo values for tier 10 SPGs in % for standing/moving/firing - source:
     
    G.W.E100 - 1.7 - 0.9 – 0,1 -> Camo as a skill is useless for this enormous artillery. Your main sources of concealment should be bushes and hard cover anyway.
     
    Here is an example of how you can use your view-range:
    Optics + arty (Note: The replay function/xvm is slightly bugged - blue circle should be at 445m and damage counter is also incorrect)

     

     

     



     
     
    I have also seen some players who mounted a spall liner on their SPGs. This is a really bad idea, because it decreases your mobility even more. It weights 1 metric ton for a GW-E100 and makes avoiding incoming counter artillery fire or infighting more difficult.
    By simply moving right after you fired, you're pretty much safe from counter fire.
     
     
    Crew skills and Perks
     
    The first crew skill for the whole crew should always be BIA (in a SPG), it increases every aspect of crew and vehicle performance by 5%. After that you are going to pick individual skills and perks for the crew members.
     
    Commander – he should take 6th sense a his second skill.
    Repair makes a good 3rd skill followed by Recon and Camo.
     
     
    Gunner - Snap shot right after BIA as the 2nd skill. The aiming circle doesn't become that big while moving the hull, so less time is wasted with aiming, even a fraction of a second will make the difference sometimes. This is followed by Repair and then Camo (useless as it is). Sadly there arn't any other options that make much sense, Dead-eye only works with AP + APCR and the accuracy and penetration of the GW-E100 isn't good enough to fire AP at tier 10 tanks on a regular basis. On the other hand I might switch Dead-eye with Camo when reaching the 5th skill.
     
    Radio Operator - Aside from Situational Awareness there arn't that many useful skills, so stick with BIA, Repair and Situational Awereness., which increases your view-range by 3%, or ~12m, camo as the 4th skill. The skills that extend the radio range are fairly useless because the maps are to small.
     
    Driver - As 2nd skill take Smooth Ride  followed by Clutch-Braking, Off Raod Driving and Repair. Smooth Ride also "makes sense" for artillery as it works like a Vertical Stabilizer, reducing the reticle bloom a little and saving some aim-time.
     
     
    Another important aspect is the re-positioning after u fired your shot. Clutch Braking and Offroad Driving skills in that order improve your mobility. It will make it harder to counter you even if you re in a G.W.E100, proper terrain utilization and evasive action right after you fired is needed of course.
     
     
    Loader - Safe Stowage should be the 2nd skill for one loader because artillery are prone to ammo-rack explosions when hit or splashed. The other loader specific perks (adrenaline rush and intuition) are also usefull from time to time so one should use them. With 0.8.6 AP shells on GW-E100 became more useful with a buff to 303mm pen (+60mm). That's why I recommend putting Intuition on both loaders now. Intuition is the only perk which is cumulative giving you 34% chance (if both loaders have it - 2x17%), to switch to another shell type without losing your loading progress.
     
    Aside from that just take repair and after that camo.
     
    Regarding Repair - It's also makes sense for artillery. If enemy artillery or a tank in close combat tracks you, it often helps you to survive these tricky situations by getting them up faster. First time you will use your repair kit of course but after that this skill can save you. I often encountered enemies that where really surprised how fast I had my tracks up and started to turn the 21cm of doom into their face. It won't help against good players but the less gifted ones are in for a surprise.
     
    The following mods can really help you to become a better arti player:
    Reload timer and shell travel timer zoom mod (original source - Russian WoT forum) XVM shows who is really dangerous in the enemy team and should be taken care of first and the minimap mods included are also helpfull* The old serverside crosshair (original source - Russian WoT forum) from 0.7.4 and before („caps-lock+0“) is also a must have in my opinion. The difference between client and server can be really big especially for players with ping above 70ms or an unstable ping. So I strongly advise to use it for better accuracy. The current implementation by WG leaves much to be desired. It's too jumpy for playing tanks or even aiming with artillery in close combat.  
    *A few words regarding XVM-stats:
    What I 'd like to address is how some arti owners try to use especially the stats in XVM. No one is arguing the fact, that it is usefull to take out the most dangerous enemies, the question is at what cost? Not to long ago I had a memorable game in one of my artillery. The whole game some red scrubs tried to counter me, they didn't even manage to damage my tracks. They were so obsessed with that purple color in XVM and countering, that my team had more or less nothing to worry about from their direction. On the other hand, I did damage by shooting enemy tanks.
    And the same can often be observed with tanks. Sure it's easier to harass a tank instead of playing counter arty, though the result will often be the same. You don't help your team with such nonsense. If that blue or purple player is as easy to hit as other targets go for him, but focusing on 100 m² of the map 80% of the game, because some purple over target marker is grinning at you , won't increase your chances to win, in most cases the opposite is true. A unicum without a team to support him or acting as meatshields is pretty easy to kill, if your team has a few players left. Even Emu87 (EU server pubstar) managed a Kolobanov medal only every ~2000 games.
     
    Another benefit from looking at the colors in XVM - check out the enemy artillery player when the counter runs down at the start. Is he red or yellow? If that's the case you have a higher the chance of countering him yourself, if the game allows it. These guys tend to go to their favorite spot and never press "W" or "D" the entire game.
     
    Playing the G.W.E100
     
    ... isn't that much different from GW-Tiger. The most important thing for me is to position these slow moving and turning giants in a way that doesn't hinder acceleration or even support it. That means stay on solid or at least moderately soft ground. Areas on the map that have a high ground resistance will make you an easy target for enemy counterfire or approaching enemy tanks because it slows you down even more. You can improve your mobility by parking these artillery on small bumps in the terrain which gives you a nice speed boost when moving down from them after your shots. Don't park your artillery in terrain depressions unless they are big enough for unhindered movement after every shot, climbing out of there is a really a time consuming operation.
    After you gained some speed also turn slightly left or right or even move backward right after your shot. Movement patterns make you predictable and easier to counter.
     

     
     
    Also avoid flattening trees, walls, fences or other stuff as it gives away your position. Otherwise you might end up like the poor noob in the pictures below, he got "countered" before even firing his first shot.
     

     
     
    Shooting and aiming with the G.W.E100 is similar to the GW-Tiger except that you have a bigger gun traverse, 6° to each side compared 5° on the G.W.-Tiger. Most of the time you have to use HE shells, nevertheless some AP can also come in handy from time to time. Don't worry you can carry 30 shells so you won't run out of ammo. The G.W.E100 sadly „only“ has 303mm penetration with AP and the accuracy on greater distances isn't that good either, which makes HE the ammo type of choice. You can try to shoot the sides of E100s and Maus with AP but all other tier 10 tanks are ether hard to hit or have to much armor to penetrate them reliable from greater distances (AMX50B is of course also easy to penetrate but quite mobile). AP on the GW-E100 works good in in-fights or city fights when you can suprise your enemies or against mediums in close range sometimes, but that is often like Russian roulette, so better stick with HE there and maybe ram them if you managed to track the them (~87,5 t is your weight, don't forget that).
    If you 're getting rushed by tanks and you can't run away, which is most of the time, park the rear of your vehicle on a slight bump in the road or ground to compensate for the bad gun depression (0°).
     
    Aiming with the GW-E100 … well there is no way to describe it properly, it comes down to experience and practice. I can only give some hints. The german „21cm Mörser 18/2“ takes the 2nd spot in the arc of trajectory*. While the Obj 261 has a flat trajectory often resulting in shells that fall short, the G.W.E100 after 0.8.6 has the 2nd highest firing arc. What does this mean for aiming? When you shot a stationary target lets say a King Tiger or E-75 the upper front plate or turret front where the gun emerges from the turret are probably the best spots to aim. The Obj 261 on the other hand will aim at the turret roof. And always keep in mind the difference between server-side cross-hair and client-side. The server-side cross-hair is lagging behind the client-side in most cases at least for people with a higher ping (50ms+) or when there was a packet loss or lag spike.
     

     
     
    And what about that battle assistant mod you might ask - well, it's s***. There is only one situation where this mod is better compared to WG standard aiming, shooting at tanks standing still on flat terrain - the easy shots. The perspective used in this mod makes it very hard to judge where to aim when the tank is moving especially when it isn't directy into your direction or perpendicularly to your aim. There are two other negative aspects in regards to the mod, that are ignored mostly:
    It compresses and warps the aiming circle compared to the top-down view, which otherwise can give you hints where to aim by the form of the ellipse/circle (terrain depression, bumps, hills and so on) When only parts of the target are visible and the rest of it is hidden behind some rocks or other hard cover, the ability to easily point at these open parts of the tank often misleads artillery players into taking shots they shouldn't take in the first place. With low tiers artilleries and reloads under 20 sec it's not that bad, but if your reload is 40 sec or longer it becomes a problem. In these cases it's often good to check if other targets are available or wait with that shot.  
     
     
    The first video is one of my best rounds, in terms of experience earned, in the GW-E100, scoring more than 1800XP and 7 Kills on Swamp in a random battle from February 2012
     
     
    The second video is one of the notorious "PTS-Arty-Parties". It was really fun to take part in those, as long as you are in the right team. The replay is pretty old from beginning of 2012, taking place on El Halluf – enjoy!
     
     
     
    The two videos are from the 0.7.1.1 game version. Sadly I wasn't able to capture the in-game sound there.
     
    Something more recent - 0.9.0 - with some commentary from me (sound volume is very low). As I don't have an internet connection fast enough to upload YT videos, I don't have something else to offer. Though that way you can compare pre and post 0.8.6 GW-E gameplay.
     
    https://youtu.be/7AwVGpJHPuA
     
    A word regarding the arti rebalance that happend with 0.8.6. Overall the G.W.E100 didn't suffer that much from it compared to other top tiers SPGs, the thing I noticed is a slightly worse aimtime and a little longer reload. On the other hand the buff to ~300mm AP penetration was something usefull. As it is now arti accuracy is slightly worse as before 0.8.6 at least for the top tier SPGs - can't comment on lower tiers in general, I don't play them. Beside the bad mobility the G.W.E100 is a good allrounder, but not really suited for CW. Specialists like the CGC or 261 are often more usefull there.
     
    And what about the german SPG line as a whole? In my opinion it has two "highlights" the Grille and the GW-Panther. Both are excellent SPGs for their tier, especially the GW-Panther is a must have for the SPG-Missions in my opinion.
    And what about the Hummel, I heard it is a beast?! Well that was probobably an oldtimer remembering the WoT beta. The Hummel after patch 0.8.6 is only a shadow of it's former glory: inaccurate, long shell travel time, relative flat trajectory and with +3° of gun "erection" useless when it comes to close combat. About the german tier 8 and 9 artis ... I don't want to speak about them, it's wasted time - get yourself a M40/M43, M53/55 or a FV207 instead.
    So should you go down the german SPG line to tier 10?
    If you are looking for a SPG to use in CW - no. First get the CGC, the Obj. 261 and the M53/M55 (the T92 is a desater after 0.8.6). If you want to have some arti fun, it's best to stop at the GW-Panther for most people. Me and my 2000 battles in the G.W.E100 is a different thing. It was my first tier 8 (now 10) arti back in 2011, researched it initially for CW and I got used to it's limitations by now.  
    I hope you gained something from this write up. A big thank you to PityFool [NA] for spell checking this - your inner grammar nazi rocks!
     
    If you like you can leave a small tip below - thank you.
