RadeonSI Mesa 17.1-dev vs. AMDGPU-PRO 16.60 OpenGL Linux Gaming
Starting this OpenGL Linux gaming comparison off with BioShock Infinite, for this particular game the AMDGPU-PRO driver remains much faster than RadeonSI on Mesa 17.1-dev for the RX 470. There had been some BioShock Infinite optimizations in RadeonSI, but it looks like more work is needed.
AMDGPU-PRO is also still currently faster than RadeonSI for Deus Ex: Mankind Divided. Marek and others had done some optimizations to RadeonSI/Mesa for this game, but it looks like more work is still needed.
DiRT Showdown had ran fine on RadeonSI but was consistently crashing with AMDGPU-PRO 16.60.
With Metro Last Light Redux being fairly demanding, it's good to see RadeonSI is running faster than AMDGPU-PRO's OpenGL driver.
For those looking to relive older games on Linux, Portal's high frame-rates were even higher with RadeonSI.
