Has anyone had any problems with the anti aliasing options in game not actually doing anything? I apply them but there is clearly no anti aliasing applied to the image quality and the performance isn't affected either. I can however force anti aliasing within my Catalyst Control Center. I'm running the latest patch.
I'm running the following system:
Phenom II X3 720 BE @ 3.5Ghz
HD 4850 @ 700/1100 - Catalyst 9.8
4GB OCZ Reaper DDR3
Windows XP Pro SP2
