Mesa 20.3 + Linux 5.9 Is In Great Shape Against AMDVLK, AMDGPU-PRO
Total War Three Kingdoms was running into stability issues with AMDGPU-PRO. Mesa 20.3 with ACO was in the lead anyhow.
Total War: WARHAMMER 2 saw similar performance between the updated driver options. This was another game where moving to Mesa Git or newer Mesa snapshots compared to Ubuntu's defaults can pay off.
