Linux 4.12 + Mesa 17.2-dev Yields Noticeable Advantages For Radeon Gamers On Ubuntu 17.04
Portal was tested for being a light game that should benefit from the recently-landed RadeonSI threaded pipe_context work. Sure enough with the newer 4.11+ kernels and Mesa 17.2-dev, Portal is 26% faster.
Tesseract also sees noticeable gains on this Radeon R9 Fury + AMD Ryzen 7 1800X system with the newer kernel and code.
Team Fortress 2 only saw small gains in performance with these updates.
The Tomb Raider performance was also about flatlined.
