Persistent FPS Drops in War Thunder: Seeking Solutions

thank you for your research however my System would still be the oddball here

since I use a quadro instead of a Geforce series card I don’t have Geforce Experience installed and the entire UI for the card is a different one

nonetheless I’ll see if I can replicate your sucess

Worked for me, average start of the gameplay went from 15 fps to 90+ fps, thanks a lot!

Has a fix been found ??

nope

Vsync or other FPS locks in games , not only WT but other games as well doesn’t have a proper effect you have to lock FPS in Nvidia Control Panel or Adrenaline.
That way you get away from FPS spikes or regular oscillations, reduce GPU temps and reduce unnecessary power draw of your GPU, power that creates heat.

I had the same issue, Windows is the problem, with the GPU scheduling that sometimes messes up with the game and the gpu driver, i disabled the feature an everything was nice and smooth.

Windows settings → System → screen → Graphics → chage default graphics settings → gpu scheduling

got an 4070ti a r7 5800x3D with 16gb ram and gen4 m.2 ssd bty.

I have same issues still with razen 9 5950x and rtx3060Ti at 1080p. I use this resolution cause I stream. It drops from around 200fps to just a little over 30fps. Sometimes tabbing out of the game and coming back negates the issue, but it comes back soon after.

Been having a similar issue, i run about 100 fps but with microstutter, happening about every few seconds. Running on 7800x3d, 4060Ti 16GB, 32GB ram @6000MT/s, 1440p. The game files are on pcie m.2 ssd (although only gen 3) haven’t yet looked at frametime but it’s pretty obvious that frametime is the issue. I am on the latest drivers and windows updates (win 11). For some reason I can’t even enable v-sync in the settings, though it wouldn’t help as I have a 180Hz monitor. I even overclocked my gpu using the Nvidia tool for it bu to no avail. Gpu utilization is at 99% and cpu is pretty low tbh (around 20%), but that’s to be expected I guess. I have been having this issue for quite a while, but before I thought it’s just my hardware being too slow for the game (I have played on my old laptop with 8th gen i5 and 1050ti mobile, and then on 10th gen desktop i3, both of which are just 4c8t cpus). But now after finally upgrading my pc (i know that the pairing of cpu and gpu is not good, I bought this gpu few months ago, with planning on getting the new 50 series card or just buying a 2nd hand 4080/4080super when the 50 series come out) I don’t really see any issue as to why this stuttering should happen. Anyone got any tips or ideas? Thanks a lot.

Thanks man, this resolved the issue for me!!

Hi all, I get this micro stuttering/freezing all the time now. Things I’ve done:

  1. Direct wired the laptop to the modem
  2. Increased download speed to 50MPS
  3. Deleted the NVIDIA’s Overlay.

None of this did anything. I was hoping someone could tell me whether of not my computer is good enough for the game (it is 3 years old now).

|Processor|11th Gen Intel(R) Core™ i5-11400H @ 2.70GHz 2.69 GHz|
|Installed RAM|16.0 GB (15.6 GB usable)|

TIA

Welcome to the unfortunate club. I have had this issue for quite a long time and my original bug report got closed.

If you want to help out please post your info in the bug report!

I’m facing the same problem with Ryzen 7 5800X and RTX4060TI, huge fps drops when zooming, one possible solution is reducing or deactivating terrain displacement, that partially help with it, at least for me, I still have fps drops when zooming, but only on a specific map (north Holland) every time I zoom specially from a plane it go from 120fps to 10fps on a second, you can avoid it, deactivating ray traicing, but is annoying because it only happens on that map, plus, I still have problems with desert maps, like sands of sinai, tunisia or american desert, every time I play those maps, on a random moment in the game, it show me a “graphic driver failure” and reloads all the graphics (on about 15 or 20 sec) I don’t know why only happens on desert maps, maps like Alaska with a lot of windows or sweden doesnt give me any troubles at all. My drivers are up to date by the way.

Is important to add the resolution you are using.

4060 Ti has slow VRAM and only 8GB, depending on your resolution and game setting you might encounter stutters. If you are on 4K or 2K you have to lower your details in the game, VRAM bandwidth of 4060Ti is very low to be used for 2k and 4 K resolutions.
4060 is mostly for 1080P gaming.
128 bit on 4060 VRAM is really very little for 2k and 4K resolutions.
If you plan gaming on 2k and 4K than you are looking at 256 bit VRAM upward.
In some titles for example 4070 with 12GB 192 bit might be good but it might stutter in other titles.

I recommend you get 4070 Ti Super as it got 256 bit 16 GB ram for 2k/ 4K.

It happens more on Dessert maps because of the dust, your VRAM can’t cope with it, is overwhelmed.
Lower Particle Density in your game settings.
Lower some textures as well.

I read your bug report try the following. 3090 are powerful GPU but is really worth capping your FPS let’s say to 100, go to Nvidia Ctrl panel > program settings > warthunder > Max Frame Rate chose 100 FPS.

Most of people doesn’t see over 100FPS anyways so is just heat for your GPU and wasted electricity (3090 can easy go over 400Watt power consumption)

Why capping - Stability in many games less heat for your GPU.

Also download HWinfo, run it in the background while playing the game, report back, with your 3090 temps on Memory Junction, is easy if you upload here a print screen of your HWINFO GPU section.

I need temperatures on your VRAM (memory junction) using HWINFO Run the game for 30-min-1h , pritnt screen HWINFO with GPU section and post it here. RTX 4000 Quadro is blower card with very little cooling as it got small radiator and one single fan so probably your VRAM is sizzling.
In terms of choice of GPU would have been a better choice RTX A 4000 -16Gb/256 bit

Cap your WT in Nvidia CTRl Panel at 75 FPS max. If I was you, I really wouldn’t venture with that card, 8GB VRAM at 100 FPS @ that screen resolution. Also capping your FPS will prolly save your GPU of frying one of the mem chips.
Your expectations from your hardware are too high.

I have a 240 HZ monitor, and while I do not need the FPS to be that high I want to get it as high as I can since I can tell. Also having high fps should not cause this unless there was a CPU bottleneck or a bug with the game or driver.

With stock cooling this card goes to 92°c on light duty yes

I’ve pointed 3 Noctua 140mm fans and a 230V 150W Industrial Impeller in it’s Direction and now it only reaches 89°c but it no longer thermal throttles

this redneck cooling solution gave me a 500% performance increase

even tho the card is quite old it’s doing modern games at OK settings even, I assume even better cooling could increase performance even more but that would require water cooling by now

As I expected, 89c means your VRAM chips are sizzling at about 105 C which is critical.
Your solution doesn’t work, 3C less is not enough.
If I’ll be you I’ll deshroud the card, put 2x 80mm fans above radiator + 1X 92 mm fan pulling from the back of the card, pulling not pushing, make sure the exhaust fan of the case runs at high RPM is the closest to your GPU. Again has to be pull . Use mounting rubber pins or some pieces of wood to support the fan and give a bit of height.
Don’t know if you are able to deshroud the card but, for start add the 92 mm fan on the back of the card right where is that square formed out the mounting screws, fan has to be in pull not push.
Like this : Summer time and GPU is sizzling! If your GPU gets too hot try this

I have an 1080 Ti with faster memory 352 bit vs 256 bit(your card) and 11GB vs 8GB on your card. I’m running WT in high and ultra custom setting @ 1440p but capped at 80 FPS, my card pulls max 280 Watt yours only 160Watt.
More power means more heat yet, I’m running WT with max 62 C on GPU and 55-57 C VRAM, I’m running a 92 mm fan on the back of my card though @ 1000 rpm.
However I service my card, changed thermal paste on GPU itself and changed old now spent thermal pads with thermal putty so the temps dropped considerably because of that.

Will be helpful to add a picture of your fan setup but, what I’m thinking is that the 3 X140 mm are pushing towards the card but hot air is spread around and recirculated by your card, Hot air from your card has to go out of the case as fast as possible.

You have to really service your card and till than cap your FPS that is the most important things to do.

And remember GPU will throttle down if GPU is very hot but not when VRAM is very hot so you are in danger to brick your card because 89 C on GPU means 105 C on VRAM. Most GPU will have 15-20 C on VRAM above GPU temp and VRAM cooling is your focus here.

You can have 500 Hz monitor it doesn’t matter, I seen your bug report and the huge spikes of your GPU but judging by your answer not sure you want help.

I didn’t say game or the drivers are perfect but capping your FPS will help.
Other games have same issues I seen it so many times but FPS capping helps.
If is CPU bottleneck FPS capping will help again. I hope you understand why is that.
Your card use a lot of power which = heat, heat will render the thermal pads and thermal paste dry and very inefficient in taking out the heat towards radiator. Not sure if is the case but you didn’t post a picture of your HWINFO as I requested, so not sure you want help. I can’t diagnose without data.

Also you have to use MSI afterburner and Riva Tunner to see VRAM usage and GPU usage also temps while gaming, is important in diagnosing the problems.
Regarding your ability to see more than 100 FPS on your screen I guess you have to pay for some eye test to really conclude is worth running games more than 100 FPS. there is no such test in my area but maybe you are in luck.

oh btw. the FPS drops have been gone for a while

I no longer have any issues with my system

the GC has reached the end of it’s life soon anyways, I’m not going to put more work into it because it’ll still be the Bottleneck of the system even if the temperatures are fine
