I have a Evoc 1707 (clevo x170km-g)
10700k under volted -60 and locked clocks at 4.5 performance mode
2 power bricks
I just got this a week ago. THis doesnt happen all the time and happens seldom. When it does happens GPU usage drops so fps drop also. I emailed the company i bought it from HID Evolution and they said it could be the power bricks. Im not so certain. I also had this drop in cyberpunk 2077.
Things i tried using DDU and reinstall gpu drivers
Putting perfromance mode in nvidia control panel.
