AMD Radeon Gallium3D Is Catching Up & Sometimes Beating Catalyst On Linux

With Team Fortress 2 the open-source AMD Linux driver outcome is even better with the performance being roughly the same -- and in many instances better -- than the Catalyst driver tested on Ubuntu 14.10. For both the R600 and RadeonSI Gallium3D drivers, the open-source code was offering great performance that met or exceeded the Catalyst driver performance. There were no rendering issues in TF2 for either of these AMD Linux drivers.

The Catalyst Linux graphics driver also showed higher CPU usage than the open-source driver.
