AMD Catalyst 2013 Linux Graphics Driver Year-In-Review
Unigine Heaven 4.0 was broken on Catalyst 13.4 for this Radeon HD 7950 system, but at least when comparing Catalyst 13.1 to 13.11 Beta v9.4, the performance is up by 10%.
The Unigine Sanctuary performance regressed noticeably on the later AMD Catalyst Linux beta.
Unigine Tropics at least worked on the tested driver releases and was stable throughout.
Lastly, the Unigine Valley performance seems to dip on the latest Catalyst Linux graphics driver.
