Persistent FPS Drops in War Thunder: Seeking Solutions

Just wondering, but, the people with problems, are you running the game with a normal Hard Drive or are you running an SSD?

Hard drives can sometimes have a transfer speed that is not quite up to what the game needs where SSD’s are quicker and best. Slow transfer speed HDD’s can sometimes cause lag, framedrops, freezes, crashes and bandwidth problems. You need to remember that game companies use fast PC’s and I can bet none of them are running any hard drives so do not consider them. They are old tech now. It’s all SSD’s now.

Spaghetti code.

for context my system is:

Spoiler

computing parts: i9 10850K, Quadro RTX 4000

memory: 6.5TB all drives are M.2 SSDs with games running on a different one than the OS( currently unsure on which one I got Warthunder), RAM 2x16GB 3266MB/s
monitor is plugged in via DP, it’s an ultra wide 3440x1080p@144fps

Not sure what’s happening with your system. Your PCU is more than powerfull enough and you have 10 cores, these days you need a minimum of 8 cores. GPU and RAM are fine and you are running SSD’s. You should be running the game fine.

What about your broadband speed? is that quick enough? Ideal ping is 10-40, especially if texture downloads are going on in the background throughout the match. Ping affects more than just gameplay transfer speed between you and the server.

What programs run in the background? Unknown to you unless you look it up, say in Task Manager, you have lots of processes running in the background including Windows updates, anti-virus updates, graphics driver updates, game updates, Adobe updates, background services waiting for hardware inputs form control pads, usb sticks, GPU speed, power and temps, CPU power, speed and temps, etc, etc. lots of background services.

A couple of years ago, I was having problems with game freezes and crashes. It turned out that “AVG Free” was taking up so much CPU resourses when it updated through-out the day, that it would freeze my games and give me massive FPS drops. A little tweaking in the options soon sorted that out.

In the past, I have slated so many games, when at least half the time it was either my PC or other programs running in the background that was serously slowing down a reasonably good PC.

Even top of the line PC’s can have problems, they are not infallable.

I’d recommend disabling DLSS regardless and try enabling war thunder’s vsync. If that doesn’t work simply upgrade your GPU driver and if that also doesn’t work uhhhhhh

It’s spaghetti code. War Thunder naturally tends towards being wonky for everyone. For me, I had a few cases of no sound, black textures, crashes. A few rare ones that I don’t recall but all has happened when your coding is essentially spaghetti and meat sauce.

ping is around 20- 35 however this is definitely not an internet problem, I’ve had those before and know that this is a different issue now

only Spotify and occasionally discord in the background, in Task manager my system isn’t remotely challenged with the game, it’s so calm with Warthunder that I once accidentally had Metro Exodus running in the background and only got a slight FPS drop

all drivers are up to date, game files have been rechecked multiple times

and yet still stutters and FPS drops
I really doubt the problem is my Machine, especially since it seems other people have it too

I may add that those drops are a new thing that started in the last few months

I only mentioned it because i have had those problems myself while slating games in the ,now, distant pass. It’s a process of elimination with PC’s, just like fault diagnosis on every bit of machinery that does not work as it should. I’m also an ex-professional mechanic so i’m also used to fault diagnostic processes.

Every problem in life is a “process of elimination”. Once all other possibilities have been acounted for and ruled out, you are left with only one option, the game coding by the manufacturer. So now you are in my position.

Now you know you have a legitimate complaint, and not just a complaint from a gamer who doesn’t quite understand how a PC works. Do not forget that Gaijin has to respect consumer rights, even if it does not want to, no matter what county they sell in, every country has laws to protect their citizens. Even if they offer it for “free”, they “still” come under consumer laws.

After conducting thousands of tests, even disabling Windows USB power debugging, since it’s said that War Thunder’s anti-cheat scans USB inputs every time it’s disabled, and even suspecting MSI Afterburner, I discovered that the conflict with War Thunder is caused by NVIDIA’s Overlay. This option needs to be disabled. Where are the War Thunder administrators to complain to NVIDIA? This option remains enabled by default, imagine how many people are having issues because of this official NVIDIA application.

Before, my graphics card stayed at 0% for a few seconds, then jumped to 100% before stabilizing at the correct value of 40%. By deactivating this, I haven’t had any more issues so far. I tested it for two days and the problem hasn’t resurfaced. Looks like that was indeed the issue.

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!
