According to the release notes, the primary advantage of the new drivers is a performance boost, especially where a game may be bottlenecked by the CPU speed rather than the GPU. Some mentioned titles are Crysis and World in Conflict. A number of bug fixes are provided for Windows Vista and Windows XP in the Catalyst Control Center, along with a handful of fixes for display issues in games and in media content like Blu-ray.
This simultaneous Windows/Linux platform release, including both 32-bit and 64-bit versions shows how ATI's GPU driver development has evolved. Linux users have become accustomed to wait for weeks or even months before seeing a driver update. This time, however, AMD is clearly showing it has the ATI driver development team on the ball which is quite encouraging.
