Mesa 20.1-dev RADV vs. RADV+ACO vs. AMDVLK vs. AMDGPU-PRO Vulkan Radeon Linux Gaming Performance

DiRT Rally 2.0 is running on Linux via Steam Play with Proton and DXVK. Aside from a hang when using ACO on the RX Vega 56, enabling the ACO compiler back-end boosted the performance for this game on the Navi and Polaris cards tested. In doing so, the ACO performance was either the best as was the case for Polaris or enough to put the Navi performance on-par with the official AMD Vulkan Linux driver options. For Navi the AMDVLK vs. AMDGPU-PRO Vulkan performance was similar while for the RX 590 it saw better performance on AMDVLK.

With F1 2017 that is Vulkan-powered and running natively on Linux, using Mesa 20.1-dev's ACO compiler back-end again provided healthy performance gains. The RADV+ACO combination was enough to offer much better performance than the AMD Vulkan drivers for Vega and Navi while the RX 590 saw slightly better performance on AMDVLK.

HITMAN 2 runs on Linux via Steam Play. At 1080p with ultra quality settings, RADV + ACO was enough to put the performance on-par with the official AMD Vulkan drivers except for the RX Vega 56 crashing with ACO.
