Radeon Software 18.10 vs. Mesa 18.2 RADV/RadeonSI Benchmarks
Dota 2 with OpenGL at 4K saw RadeonSI continuing to run much faster than the PRO OpenGL driver....
But Dota 2 with Vulkan compared to RADV in Mesa 18.2 is where we finally see the PRO driver components yielding faster performance. Granted, RADV still has room to mature and now with the AMDVLK code being open-source, hopefully more optimizations to copy.
With the F1 2017 Linux racing game that is powered by Vulkan, the results were mixed from RADV performing at the same speed as the PRO Vulkan driver to the closed up code still offering slightly higher performance.
F1 2017 overall is in good standing on both drivers, especially in recent months
