I have a gtx 1650 and i noticed while playing games, the gpu usage will gradually increase to 100%, for example fortnite, im on a constant 144fps then after a few mins it goes to like 40-50fps while my temp is at 91C and 100% gpu usage
Ive used MSI Afterburner to monitor my temps and stuff and i noticed that my gpu switches from 300 - 1410 mhz and while playing games, im at 99-100%, im always 91C even while idle
