After a long using 4.19.122, i am trying to move for a newer kernel (my xhci greatly improved since), currently it is 5.14.14 and there are noticeable slowdown. For a numbers the Unigine Heaven Benchmark 4.0 (linux OpenGL) was used.
4.19.122: FPS: 43.9 Score: 1105 Min FPS: 15.2 Max FPS: 90.7
5.14.14: FPS: 31.4 Score: 790 Min FPS: 22.4 Max FPS: 60.1
And there are flickering artifacts visible while benchmarking with newer kernel.
