Radeon Gallium3D Still Long Shot From Catalyst
With Xonotic 1920 x 1080 and high quality effects, the latest and tweaked Radeon HD 5830 graphics card was at 61% the speed of the binary blob, the HD 6570 was at 45% the speed, and the Radeon HD 6950 was at 65%.
OpenArena is beginning to be CPU-limited with the latest Mesa/Gallium3D drivers and the updates and tweaks did not end up boosting the scores for these Radeon HD 5000/6000 series graphics cards. However, the Catalyst driver still remains significantly faster: the Catalyst driver was 77% faster on the HD 5830, 2.45 faster on the HD 6570, and 51% faster on the HD 6950 Cayman.
World of Padman actually seems to regress with the very latest code that is tweaked.
