AMD APU On Linux: Gallium3D Can Be 80%+ As Fast As Catalyst
Team Fortress 2 did much better with the new Gallium3D driver and Linux 3.13 kernel than the less-than-reliable Catalyst driver itself.
Urban Terror also improved with the newest open-source Radeon driver code.
Warsow with its Qfusion OpenGL engine is now more than 80% the speed of Catalyst when using the Gallium3D driver on the AMD A10-6800K.
