When moving to high quality settings with Xonotic and maintaining the 1920 x 1080 resolution, the Radeon Gallium3D driver fell further behind and was not as competitive like the low quality settings. However, for most of the graphics cards at least on the "Tweaked Git" stack, the average frame-rate was usually above 60 FPS.
For most games, the Radeon Gallium3D driver is still far behind Catalyst, but at least as the "Tweaked Git" results show, the open-source driver code is beginning to move in the right direction. Aside from the OpenGL performance, there's still much work left on catching up to the latest OpenGL specification (right now R600g is basically limited to OpenGL 2.1/3.0), OpenCL is still an active target, power management isn't yet ideal, and there's many other features left to be accomplished or completed.
