AMD's Windows Catalyst Driver Remains Largely Faster Than Linux Drivers

Xonotic with low quality settings shows the Radeon R9 270X performing close to the same across the board and the Catalyst Linux driver even takes the lead over Windows. The Radeon R9 290 was left broken on the open-source driver but with Catalyst, the Linux driver managed to take the lead.

When using high image quality settings, the Windows 8.1 software stack returned to take the lead for both the R9 270X and R9 290.
