Anyone ever had an issue enabling AA? I do it via ATi's Catalyst Control Panel (8x) and for some wow powerleveling reason it won't apply those settings to WoW. Regardless of what setting it's on, nothing changes. There's no difference between turning AA off and turning it all the way up. Seen this before?

AA can be adjusted in the in-game WoW video options. It is known as "Multisampling" and can be adjusted as high as 8x from the in-game drop down.

Ok, after selecting "Use Application Settings" in the ATi control panel - I finally got it to enable AA. So, basically ATi's control panel is useless? I can't get it to have an effect.

WoW overrides the AA settings.
For best results, It's best to keep it at "Use Application Settings" anyways.

Ha, well thanks for the input, man. I was really beginning to lose it. Had gotten to the point where I was beginning to question whether or not I knew what AA looked like and was telling myself those awful jagged lines were actually quite delightfully smooth.
