Bug ID: 221004
Summary: After some hours FPS drop to half while gaming using
amdgpu driver with wayland
Product: Drivers
Version: 2.5
Hardware: AMD
OS: Linux
Status: NEW
Severity: high
Priority: P3
Component: Video(DRI - non Intel)
Assignee: [email protected]
Reporter: [email protected]
Regression: No
For some reason, in the Wayland session, after a few hours, the frame rate
drops by half in all games using the amdgpu driver. It seems that after playing
for a long time, the amdgpu driver changes the GPU clock to the minimum
profile, and the memory goes into idle or has a low clock speed. I ran the
command below now when the problem is occurring during the game to help provide
some information related to the problem.
