ATI Customer Care now offers downloads of new version 5.12 CATALYST reference drivers for RADEON accelerators running under Windows XP. Several game-related fixes and performance improvements are listed among the release notes, and word is: "The Catalyst® 5.12 software suite introduces dual core support for CPU bound cases. This feature provides improved graphics performance for DX 9 supported graphics adapters installed in systems running the Windows XP and Windows XP Professional x64 Edition operating systems." As noted here (thanks Ant), the Tray Tools edition of the drivers are no longer available, and the CCC edition is now required.
