Catalyst 15.5 For Linux Brings Some Performance Improvements
The most profound improvements with Catalyst 15.5 were in the Metro Redux games:
Metro Last Light Redux and Metro 2033 Redux no longer run like garbage on AMD Linux but are now delivering better frame-rates. However, there's still a ways to go with the performance when running these titles at 2560 x 1600 as the NVIDIA GeForce graphics cards are still much faster on the same system with the proprietary NVIDIA driver.
With Civilization: Beyond Earth there was no major change in performance with the R9 290 Hawaii GPU continuing to run slow on the current Catalyst Linux version.
