Radeon Software 18.50 vs. Linux 4.20 + Mesa 19 Benchmarks On The AMD RX 590

DiRT Showdown was nearly twice as fast with RadeonSI compared to the legacy closed-source AMD OpenGL driver.

With Dota 2 is another case where we see the OpenGL performance to be much better with RadeonSI but when it comes to the Vulkan performance between the closed-source AMDVLK-based driver against the Mesa 19.0 RADV driver, the performance was about the same.

With the F1 2018 racing game running under Steam Play with DXVK to run D3D11 over Vulkan, the Radeon Software driver had the slight advantage in average FPS as well as lower peak frame times.
