While Ubuntu 22.04 LTS was just released over one month ago, it is shipping on the Linux 5.15 kernel that was already two stable series behind at release time but chosen as the default due to its long-term support status. Ubuntu 22.04 also shipped with Mesa 22.0 as the latest stable version albeit the open-source OpenGL/Vulkan graphics drivers are quick to advance. So if you've been thinking about upgrading Mesa or the Linux kernel on your Ubuntu 22.04 system for better Linux gaming performance, here are some benchmarks looking at such performance impact for AMD RDNA2 / Radeon RX 6000 series graphics.

While the just talked about Nouveau beginning to land GeForce RTX 30 "Ampere" open-source support is exciting, as mentioned there still are hurdles to overcome for having good open-source NVIDIA driver performance on modern GPUs. So equally exciting news is that Nouveau has begun adapting some of their code into a standalone library so it can be used in the future by other new driver(s)...

Early bits of NVIDIA GeForce RTX 30 "Ampere" support were merged today into Mesa 22.2...

Back during the Linux 5.18 merge window in March I wrote about a big NUMA benchmark performance regression I noticed and bisected.
