Radeon RX Vega 64: AMDGPU-PRO vs. DRM-Next + Mesa 17.3-dev
The Vulkan performance of Mad Max was much closer than the OpenGL numbers. However, these numbers are very exciting as it's putting the RX Vega 64 performance in line between RADV and AMD's official closed-source Vulkan driver and even slightly faster with RADV in some scenes.
In Valve's old Portal game, the open driver stack was also much faster.
Serious Sam 3 BFE on Vulkan is slightly faster with RADV!
Though with Talos Principle, the RX Vega on RADV loses out to AMDGPU-PRO 17.30.
