If you’re on Steams version it may be something to figure out, but if you’re on Vanillas launcher, you should be able to pick the graphics setting preset.
i am having the same issue. My game keeps on freezing in the middle of matches and it sometimes even crashes. I have an RTX 4060 and an intel core i9 14900. I tried everything that you did and my keeps on crashing.
Same thing with my brother. All I know is that when he plays a game like Roblox or something, his computer fans make it like a volcano eruption is ongoing. But when he opens War thunder. The game crashes. any ideas on how to fix it?
