I see. I'm quite surprised with the current developments of NVK. It already has a better Wayland experience and runs mid-range games great. Though I'm going back to proprietary driver for now and would like to revisit NVK in the near future.
Not exactly what I want but still tried it. It shows my GPU as 0%. Is it perhaps it's set to Nvidia proprietary driver somehow? btop was showing GPU as well when I was using proprietary driver but now it doesn't show a GPU.
