Mesa 13.0 vs. 17.0 Performance For RADV/RadeonSI: Big Gains For Vulkan, OpenGL Boosts
The demanding Metro Last Light Redux doesn't see much in the way of better performance on Mesa 17.0.
Portal didn't see any faster performance with RadeonSI on Mesa 17.0, but thankfully it's already fast enough for AMD Linux gamers.
Talos Principle with its OpenGL renderer saw performance improvements for the Radeon RX 480 and R9 Fury.
When switching over to the Vulkan renderer, Mesa 17.0 was significantly faster with its newer RADV code than in Mesa 13.0.
