The AMD Radeon R9 Fury Is Currently A Disaster On Linux
Dropping Unigine Valley down from 4K to 1080p shows the R9 Fury running behind the GTX 980 Ti and is looking good. What's sad though is if running Unigine Heaven on the same hardware/software, it will hang with Catalyst.
Given that Unigine Valley is running well on Catalyst 15.7, here's a look at the R9 Fury scaling on this game on resolutions from 800 x 600 to 3840 x 2160.
When running Counter-Strike: Global Offensive at 4K, it's another example of the Catalyst Linux driver choking. With CS:GO is another example of the Radeon R9 Fury coming up short of NVIDIA's $350 GTX 970 graphics card. With CS:GO at 4K, the R9 Fury on Linux was barely faster than the R9 290.
