I tried to force AA in my AMD control panel, but it never made a difference in the game. Activating and deactivating AA in the in-game settings, also had no effect on the actual game.

I could tell it was not functioning based on using the bow - the bow string was nothing but jagged edges.

I kinda wanted to have it all turned up to see how my computer will handle it being on. Was there some funky method of activating it for ATI, or was it simply disabled for beta?

Thank you

I have an nVidia card, and the in-game AA worked just fine.

Wasn't disabled as far as I remember. However, higher subsampling gave me much better AA (to my eyes) than the AA setting.
