On average I have ~120 fps, but sometimes it drops to ~40 for a few seconds for seemingly no reason, and sometimes it doesn't drop at all for hours. Restarting the game seems to fix it but it'll happen again some time later.
my pc:
3070ti, i5 11600k (more than enough), 32GB RAM, SSD
My pc isn't the problem, it only happens in war thunder.
Any help or suggestions are very much appreciated!
