Title:
Intel Alder Lake GPU performance much lower in 6.1/6.2 compared to
5.19
Status in Linux:
Unknown
Status in linux package in Ubuntu:
Confirmed
Bug description:
Intel Alder Lake GPU performance is much lower in 6.1 compared to
5.19.
For example, benchmarking gnome-shell main running on Xorg:
6.1.0-16-generic
30.02 FPS, average: 15.5ms, peak: 16.4ms
intel_gpu_top says 211/208 MHz despite gt_min_freq_mhz==300
5.19.0-21-generic
60.00 FPS, average: 8.3ms, peak: 8.7ms
intel_gpu_top says 542/560 MHz
The issue is so severe in 6.1.0-16-generic that even triple buffering
can't fix it for Xorg sessions. It does for Wayland though.
I can work around it with `cp gt_max_freq_mhz gt_min_freq_mhz` but
probably shouldn't need to.
