AMD Radeon Performance Preview On Linux 3.8

There wasn't much to see out of Urban Terror or VDrift. With VDrift, the Radeon HD 6570 was successfully completing the benchmark on drm-next (unlike some of the other test-cases where it would cause a kernel panic and/or lock-up depending upon the test), but the performance was much lower.

Warsow is one of the games that is hugely benefiting from the Radeon Linux 3.8 DRM. The Radeon HD 6870 graphics card went from 100 FPS to more than 160 FPS. The Radeon HD 5750 went from 64 FPS to 73 FPS. The Radeon HD 6570 continued to be problematic for this 3.8 DRM.
