The next set of ATI drivers have been released. You can get the Catalyst 5.10 Drivers straight from ATI's site. They are available for Windows and Windows XP 64bit. They haven't updated their Linux drivers yet, though. The drivers provide updated support for Crossfire and fix numerous bugs in various games, including Dungeon Siege 2 drawing issues. Although ATI only recommends updating drivers if you have issues with your current setup, we all know better than that – the best of the best is only acceptable. The drivers don't seem to be a performance related update but I suggest them nevertheless.
