At start I was very disappointed with my computer performance because I knew the hardware is OK (ATI 5870). But then I turned everything on ultra setting except anti aliasing and the thing below.. cant remember the name. Then It run perfectly! But I also want that AA and the other feature to improve the visuals.
Why will my computer not run the AA? Also too demanding for you guys? I cant even run Amnesia: dark descent decent with full AA, but ofc I can perctly without. Can I change something in my amd driver? or...? answers appreciated

If i turn on AA i even can't load the game ( i have ATI 6870 ). Default setting for my configuration is 8 AA.
I thing this is a bug.

bump.
Any fixes on this?
