I reset MPO to its default settings.
I disabled G-Sync, turned off V-Sync in-game, and set the frame rate to 5 FPS below my monitor’s refresh rate, which prevents screen tearing.
I haven’t had any freezes for the past 2–3 days, but about a week ago they were occurring. It might be related to some additional changes I made in the NVIDIA App.
I tried this combination a year ago, but it ended up freezing.
And now I’ve tried the same combination again, and it froze.
Yesterday, I updated the graphics drivers using a clean installation. I then restored my previous configuration for War Thunder (G-Sync disabled, V-Sync disabled, FPS limited to 160, I have 165Hz monitor). Today, the game froze again, although the freeze occurred after an extended play session.

Try to open the game first, then right-click and go to Properties.
it feel sooo good that Im free from this suffers. I haven’t faced this problem ever since.
Windowed screen works like a charm for me
Unfortunately, it still freezes even when I set the compatibility mode to Windows 7

I noticed that for me War Thunder would only hard freeze when I alt tabbed between my browser and the game. And even then usually only if the currently focused browser tab was playing a Youtube video or something similar. (I am using Firefox as my browser, and I am on Windows 11.)
Anyways, disabling hardware accelerated graphics in my web browser settings has seemingly fixed the issue.
EDIT: I just noticed how old this topic is. This issue only started happening for me around a week ago give or take. Not sure if it was a game update or a graphics driver update that caused it.

Is the cache file for this game working properly?
After deleting it and reopening the game to play just one match, a cache file of 632MB has been generated.
After opening the game, try switching the API to DirectX 11 and turning off the Discord overlay. I kept toggling these settings on and off, and sometimes it fixed the issue, sometimes it didn’t. I’m not completely sure what the exact cause is, but when I went back to my system settings (like optimized Windows 7 settings, etc.), it seemed to help fix it.
two year old issue still in the game, absolutely ridiculous

I still get this all the time. U alt tab back and the game freezes/ sound loops.
G-SYNC on / off does nothing
1440p - 4k does nothing
fps cap - does nothing
background fps cap - does nothing
dlss off = does nothing
dx12 is buggy so useless alternative and dx11 freezes on alt tab
fullscreen optimizations off = nothing
it’s 100% a game engine problem how it interact with MPO or windows.

A measure that helped somewhat.
I set the idle FPS for background apps to the maximum of 200 FPS in the Nvidia Control Panel.
It doesn’t completely prevent the game from freezing, but it has improved things slightly.
As leaks from the original development team suggest, GAIJIN’s current development environment is an absolute disaster, so there’s probably no one capable of fixing this bug.

It’s crazy how there are 1000’s of posts on their issue tracker about this and they just give the most basic reply about nothing
People have started reporting it in Enlisted and Aces of Thunder, 2 spin off games. It’s a dagor engine issue with windows for sure.
