[RADV] Dramatically drops FPS at high settings (in the game "Ori and the Will of the Wisps") if many windows are open (4K + 50 windows or FHD + 400 windows)
Dramatically drops FPS at high settings (in the game "Ori and the Will of the Wisps") if many windows are open
How reproduce:
- Open I lot of blank Chromium windows
I used follow command (you can use any chromium based browser Google Chrome, Brave, Microsoft Edge):
$ for i in {1..46}; do google-chrome --new-window; done
- Launch the game "Ori and the Will of the Wisps"
- In the game change graphic settings from balanced to high
If the issue not reproduced (may be because of lower resolution) try create more windows on step 1.
I consider this to be a bug because amdvlk is not affected by this issue.
Demonstration video:
- Kernel: 5.11-rc7
- Mesa: git master 628ce547
- GPU: Radeon 6900XT
- CPU: Ryzen 3950X
