Hello, your GPU usage jumps to 100% even when idle, and TaskMgr reports dwm.exe consuming full resources. After reinstalling Windows, updating drivers, switching to Studio drivers, and turning off all "eyecandy" settings, the issue persists. The problem appears to start after driver version 522.25 was installed. Is this a concern or just a minor inconvenience? Thank you for reaching out!

DWM is indeed the Desktop Window Manager. Have you checked for an update? If it's already up to date, consider downgrading it. You might also adjust settings in "Adjust the appearance and performance of Windows" for more control. For details, refer to this Microsoft forum thread: https://answers.microsoft.com/en-us/wind...4d9cd9807d

Yes, I've completed that. (The thread about the thread you shared remains unresolved?)
