Gpu at 100% in games after some time

hello, i don’t know what is causing this but i’m posting it here as someone may help me

if i start my pc and start a game via steam everything is fine and i can get normal performances (like good performances) and everyusage (checked with the resource system monitor app) is normal but if i do other things (say like 30 minutes later or an hour later) when i fire a game performances are always literally bad, like some games drops fps from 180 to 20, and while i am in 20 fps i noticed the gpu is almost always at 100%. A reboot solves everything but it’s tedious and remains a problem.

i noticed that the process using 100% of my gpu is the game itself, so i thought steam was the culprit, but i updated the app in the meantime and nothing changed so it may be something else.

for the record i am on Fedora Workstation 41 and my system is a ryzen 7 cpu with a 6600 amd card, and is pretty fine to run most modern games at good fps with medium to high details

any hint?

any hint on that?kinda thinking about making a new installation

seems like it was the gpu drivers, i switched to mageia and then to fedora 42 and the issue is solved
