AMD has launched a very specific set of beta drivers to all windows xp/vista and 7 users for their ati gpus for enabling Anti-Aliasing in Starcraft2. Starcraft2 itself doesn't offer anti-aliasing, it has to be forced through 3rd party drivers. Nvidia drivers allow for it, but ATI drivers wouldn't. Now with the release of 10.7a, you can enjoy anti-aliasing in starcraft2. http://support.amd.com/us/kbarticles/Pages/ATICat107aBetaDriver.aspx Please be patient with the link, as their servers are often overloaded, and cannot currently complete requests. My general consensus, these drivers are either very inefficient, or 2560x1440 and all ultra settings plus even 2xaa really maxes out my mobility 4850. I however, can get along with the same settings except for shaders to low, and get 60fps. I was able to play a maxed dirt2 at native resolution and 4xaa, so I'm assuming it's the drivers that quite aren't up to par. Starcract2 is also very refined with its models, so enabling aa won't make that much of a difference at all. Still fun to try it out, though.
