HAGS - RedDot-3ND7355/MPO-GPU-FIX GitHub Wiki

HAGS (Hardware GPU Scheduler) is a relatively new feature introduced in win10 since version 2004.

It is known for causing issues with overlays on top of your games and such, huge performance drops and game capture issues.

Disabling HAGS may or may not help your system run games better. It varies on the builds.
