Alt-tab freezing needs to be fixed

“Damn, that’s two years of pain.”

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.

+REP alt tab crashing is annoying

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.
