AMD is preparing a brand new Catalyst driver for its Radeon graphics card series. Users, don't have to wait much as a beta version of the new Catalyst 8.6 has found its way online.
Featuring the 8.500 display driver, the Catalyst 8.6 for both the 32 and 64bit version of Windows Vista & XP comes with support for almost everything released since the days of the Radeon 9550 plus a few cards and IGPs that haven't been released just yet.
Mind you that this is a Beta driver, use it at your own risk. We have a discussion thread open on these drivers right here.
Have you read our Ruby Edition Radeon 3850 review ?
