AMDGPU-PRO 16.40 vs. Linux 4.8 + Mesa 13.1-dev Driver Comparison
BioShock Infinite is still slightly faster with AMDGPU-PRO over RadeonSI, but not nearly by the extremes seen just a few months ago before Marek landed a number of RadeonSI optimizations for this game. Now the open-source OpenGL driver performance is within striking distance of the proprietary AMD OpenGL code for this game.
Counter-Strike: Global Offensive at 1080p saw RadeonSI being slightly faster on the R9 285 and about the same performance with the RX 460. However, with the RX 480 and R9 Fury these higher-end cards had better performance with AMDGPU-PRO.
CS:GO upped to 4K saw AMDGPU-PRO being the fastest on RX 460 and RX 480 while now the R9 Fury and R9 285 were faster with the fully-open code.
