AMDGPU-PRO Beta 2 vs. Mesa 11.3 + Linux 4.6: Very Competitive For Linux Gamers

AMDGPU-PRO Beta 2 vs. Mesa 11.3 + Linux 4.6: Very Competitive For Linux Gamers: Following last week's AMDGPU-PRO 16.20.3 "Beta 2" driver release of AMD's new hybrid driver stack for Linux that makes use of the AMDGPU open-source kernel DRM driver with the closed-source OpenGL driver derived from Catalyst / Radeon Software, I set out to do a fresh open vs. closed-source driver comparison. For the Radeon R9 285, R9 290, and R9 Fury, I compared the performance of this new AMDGPU-PRO driver against Mesa 11.3-devel Git and Linux 4.6 for the latest open-source driver stack.
