The AMD Radeon R9 Fury Is Currently A Disaster On Linux
Tesseract is an open-source game engine that's probably never been looked at much by AMD's (or NVIDIA's) driver teams so at least it's sort of a neutral test compared to the AAA Linux games. With Tesseract though the Catalyst Linux driver still led to piss poor numbers for the R9 Fury. The Radeon R9 Fury at 4K for Tesseract was pushing 153 FPS while the GTX 970 was at 159 FPS.
While Unigine Valley has been around for a while now, it remains one of my favorite Linux OpenGL tests for being freely distributable, not requiring a Steam install, and is among the most demanding Linux test cases. With Unigine Valley we finally see a decent showing out of the Radeon R9 Fury with it coming out just ahead of the GTX 980 but behind the GTX 980 Ti.
