The Catalyst 10.1s were published a few days ago, with the next version not expected before the month of February. However, Mass Effect 2, the latest title from Bioware has come out in the meantime and causes a problem in some cases when used in a CrossFire configuration. It looks as if isn’t possible to activate antialiasing in this mode.
To remedy this, ATI have just published a hotfix, in the form of the Catalyst 10.1 Beta. AMD will not be giving any support on these drivers, with the next official WHQL version still being the 10.2.
