Upgrading Ubuntu 22.04's Kernel & Mesa For Better AMD RDNA2 Performance: 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.
