AMD has improved OpenGL performance on ATI X1000-series products with Catalyst 7.2. “Gains of up to 25% in Doom 3, 48% in Quake 4 and 21% in Prey can be seen on a variety of ATI Radeon™ X1000 cards. These performance gains are noticed under the Windows Vista operating system,†according to the ATI Catalyst 7.2 release notes.
While the drivers are on par with what you would expect in XP, the Vista version still leaves a lot to be desired. Owners of the X1950XT will be upset to know their card is not supported, along with their AIW and VIVO line-up. Vista has been out for near a month now… we really should be seeing better support by now.
