20-Way GPU Gaming Comparison With March 2020 Linux Drivers
Deus Ex: Mankind Divided as ported to Linux by Feral Interactive remains one of the most demanding OpenGL games. The Radeon graphics cards on Mesa 20.1's RadeonSI driver were still standing up well against the NVIDIA Pascal and Turing competition.
For Deus Ex: Mankind Divided on Linux at 4K, the only graphics cards delivering above a 60 FPS average were the NVIDIA GeForce RTX 2080 Ti and TITAN RTX.
Running Feral's Linux port of Dawn of War III with OpenGL was very surprising: the optimized RadeonSI Gallium3D driver put the RX 5700 XT even ahead of the RTX 2080 SUPER and the other Radeon cards were also offering fierce competition.
But when switching over to Dawn of War III's Vulkan renderer, the Radeon competition was much less even with RADV ACO being enabled on Mesa 20.1-devel: the Radeon VII and RX 5700 XT were now slower than the RTX 2070.
