Mesa 22.2 Gaming Performance With Radeon RX 6700/6800 XT Graphics Cards On Linux
Aside from performance, Mesa 22.2 may be worth upgrading to for any video acceleration improvements, the Venus Vulkan driver if using it for virtualization, improving the still maturing RADV ray-tracing support, or other specific reasons.
Some configurations with Total War: Three Kingdoms did see slightly better performance on Mesa 22.2 compared to Ubuntu 22.04's stock Mesa 22.0.
Total War: WARHAMMER III recently released for Linux by Feral Interactive did see some very minor improvements with the newer Mesa.
