Discussion DWM.exe using 100% GPU all the time (Nvidia) (fix)

[Colif]

If you find your Desktop window manager uses 100% every other second, even at idle on desktop

Go to settings

• System
• Display
• Graphics
• Click Change default graphics settings
• Disable Hardware accelerated GPU Scheduling
• Restart PC

disabling the hardware acceleration has sure made my GPU cooler, was on 54c, now 46c. Nvme also dropped as it was heated/cooled by GPU exhaust

thats on 22h2 i guess, microsoft stopped offering it as it enables gpu debug mode which isnt supposed to run in user enviroment...funny thing it was reported on insider build aswell before it went live

but its related to nvidia frameview..disabling this service fixes it aswell

If i read the front page I might know that.

I knew that stopped but didn't know why. I assume they will fix it soon.

Nvidia released a driver in a few months ago to fix it, supposedly. I had not noticed the constant action on GPU until yesterday and went digging.

Probably fix it about same time as I get an AMD GPU.

Nvidia fixed it, was a driver error - https://www.neowin.net/news/nvidia-...1-bug-causing-100-usage-on-idle-geforce-gpus/

I have since reversed the steps above since its back to normal
