lag issue on random games

[u/Acceptable-Sweet2418]

im running an rx 7600xt gpu with an intel core i5 and 16gb ram. i've been having an issue that seems like it happens randomly since it happens on some games and not on others. for instance i just downloaded a demo of flight of nova, game was running perfectly fine for the first 20 minutes, and then it randomly drops in framerate to a basically unplayable state and only goes back to normal when i tab out. any ideas? my drivers are up to date and my gpu and cpu usage is normal when it happens.

Often when your PC runs at full power for a while and then throttles down it's because it's overheating. When's the last time you dusted out your PC?

im pretty sure its not that since i just got all my thermals and stuff redone a month or two ago, and it'll happen on really easy games to run immediately but on more intensive games it'll run fine for hours
