I have been playing on this laptop for a long time on consistent 60 fps with no issues. However, I downloaded War Thunder from Steam yesterday and it worked well, but after an hour the FPS dropped to 30 and got capped there for no reason.
I restarted the game, restarted the PC, disabled V-sync from Nvidia control panel, and deleted the whole game and its driver. Still, the fps starts at 60 and then drops to 30 after some time on all games.
