So what are the AA settings in relation to actual AA?
low = 2
medium = 4
high = 6 ?

The reason I'm asking is for some reason i don't get an option for medium or high, only low. I'm satisfied with my game speed now and don't want to lag it any further. What setting should i set it to?

I have a 9800 pro 128mb card and P43.0E (~5900 3dmarks w/ 2003) and playing on huge unit size. Any suggestions from similar hardware owners? I was thinking of making it 2x in my CP with temporal AA. But if low = 4x, then i'll set it to 4x w/ temporal AA.
