An Early Look At The Ubuntu 22.04 LTS Performance On AMD Ryzen 9 5950X + RX 6800
When it comes to the open-source Radeon graphics performance, there are some improvements in the likes of GravityMark and Unigine that were actually in a regressed state compared to even the Ubuntu 20.04.4 HWE stack.
For Radeon RX 6000 series graphics already being quite mature for Ubuntu 21.10, there isn't much in the way of broad RadeonSI/RADV improvements in Ubuntu 22.04 LTS. But there is the experimental RADV ray-tracing and other targeted improvements and many game-focused driver fixes.
