WarThunder + Nvidia + Linux = stutter (how can I fix it?)

Bugs

I am getting constant stutters in WT since the 2.x update - it was perfectly smooth on 1.x (basically - previous dagor engine). It is like it micro-freezes for couple of frames, so even though fps is high, the game feels laggy - makes aiming really difficult.

Currently I use archlinux with latest 455 series nvidia drivers (card is 1050M). I have tried the following:

  • Using older kernel versions
  • Using older nvidia drivers versions
  • Using different desktop environment (XFCE - compositor on/off, Gnome)
  • Changing WT graphical settings ranging from ULQ up to medium with many manual tweaks

Sometimes the stutter is more noticable, sometimes less, but it is still there.

I have ruled out so far:

  • General performance - this should be OK, as I get 100-150 fps with vsync off (and it still stutters)
  • Thermal issues - GPU and CPU never go above 65 C
  • Memory issues - it tops on 3GB used out of 16GB available
  • Other processes - WT was only application running

What other steps can I try?

(Yes, I know, I know, Linux gaming lol, but I am stubborn, OK?)

I know, right? But this is better for my opponents, so at least someone is having fun...

If you're on a mechanical drive, you should run a full S.M.A.R.T scan on the thing.

If you're on an SSD, you should take it to the linux issues subforum on the official forum ( https://forum.warthunder.com/index.php?/forum/923-linux-related-problems-advice/ ).

I have bought a brand new SSD partially for that reason. Didn't help - it still stutters on HDD and on SSD.

And yes - I'll take it to the official forum. There were some similar issues in the past, but I cannot see anything current. But first I want to make sure that this is game issue, and not my config issue. Maybe there is a fix for that already, that I don;t know?

I also have bad performance on archlinux, on Pop_OS! or any other ubuntu based distro I have excellent performance, but I'm using amd gpu, still very strange. My problem is memory leak, pc crashes after a few games. Without vsync I also have stuttering, with vsync on I don't. I don't know maybe you could try to limit fps? Maybe mangohud can limit fps on WT. Or try Pop_OS! maybe?

I actually have a small issue with freeze stutters as well since update, on a high end machine. They are so infrequent and far between that it doesn't bother me that much, but they do bother me.
