Since the open-source results earlier this month, fixes landed in Mesa Git for improving the R9 Fury (Fiji) performance. However, even in looking at the R9 285 results for Metro Last Light Redux, this latest open-source AMD stack still has a ways to go in outperforming Catalyst. For Metro Last Light Redux the Tonga GPU was running at just over 60% the speed of Catalyst.

With the basic OpenArena game, the R9 285 was at 88% the speed of Catalyst. The Mesa revision as of earlier this month was unstable for the R9 Fury.

With the Tesseract open-source game the Tonga GPU will be at over 70% the speed of Catalyst once this PowerPlay support is merged into Linux 4.5.
