    We are talking about fluctuating usage of GPU mostly while laptop is idle, there's no drop in performance, just battery drain. I went in depth with this problem and tried to fix it with multiple drivers, reinstalling OS, different power management settings in both, windows and Nvidia drivers, tracking culprit with GPU shark and process explorer. Nothing to share so far. Reinstalling drivers always does the job until i reboot 2nd, after that fluctuating starts and never stops

    PH 317-52. Noticed artifacts when running uniengine heaven benchmark, ONLY when tessellation is on.
    Went so far to install windows 11, issue is still there

    Update:
    One might think that it's tessellation unit being damaged due to artifacts with it enabled but further investigation revealed something else is being drawn in DX 11 mode of heaven benchmark, and tessellation is just being drawn over it when enabled

    This issue may be related to some nvidia video card issue.

    Setting multi display power saver via Nvidia inspector does prevent artifacts from happening in heaven benchmark and games with heavy tessellation usage

    Do these artifacts appear on the laptop's display?

    I had the same problem. But I found the solution. The problem is because of the nvidia in-game overlay. Solution is reinstalling the gpu driver and never using nvidia in-game overlay again. You can still use any other application instead like msi afterburner.

Nothing to share so far. Reinstalling drivers always does the job until i reboot 2nd, after that fluctuating starts and never stops, The latest nvidia 471.11 graphics driver caused the same problem. Wireclub You need to install an older nvidia graphics driver.
