AMDGPU-PRO 17.10 vs. Mesa 17.1 RADV/RadeonSI Performance
Dota 2 with its OpenGL renderer experiences much nicer performance with RadeonSI than AMDGPU-PRO.
But with the same Dota 2 test at 1080p using the Vulkan renderer, the AMDGPU-PRO driver is much faster than the community-maintained RADV driver on the Radeon RX 480 and R9 Fury.
When running Dota 2 at 4K with OpenGL, the RadeonSI-based driver stack remained superior to AMDGPU-PRO...
But with the Vulkan results, AMDGPU-PRO was still faster than RADV.
