To no surprise, with the FirePro graphics cards, the Catalyst driver is multiple times faster than the latest open-source driver using Gallium3D. The FirePro V3800 is 3.1x faster with Catalyst, the FirePro V4800 is 5.1x faster with the blob, and the FirePro V8700 is 6.4x faster. The two Radeon HD graphics cards were 5.1~5.3x faster with the Catalyst driver on the same system.
On the Radeon HD 4770/5770 and the FirePro V4800/V8700 graphics cards, Warsow was roughly five times faster with the proprietary driver. With the FirePro V3800, the Catalyst driver was only 2.87x faster than the Gallium3D driver, which is not even playable on the V3800 with a 1920 x 1080 resolution.
