AMD has released this month's Catalyst 8.4 driver set. Like every Catalyst monthly release, this driver set contains a few fixes for games running in Windows XP, XP x64 and Windows Vista. The list of fixes and known issues in this Catalyst version can be found here: http://game.amd.com/us-en/content/pdf/Catalyst_84.pdf
Here is the link to the drivers:
Windows XP/XP x64/Vista 32-Bit/Vista 64-Bit: http://game.amd.com/us-en/drivers_catalyst.aspx
Installation Instructions:
1.) Unininstall the ATI drivers from "Program Add/Remove"
2.) Install and Run Driver Sweeper with "ATI Display" selected. (It's recommended to do this, so that left over data from old graphics drivers don't conflict with the new ones.)
3.) Restart the computer.
4.) Install the new Catalyst drivers.
