AA (antialising, spelling?) reduces jagged edges and smooths non-horizontal/vertical lines.
Yeah that's the more technical term

Not worth the drop in frame rates from 4X to 16X or anything else IMO.
If it drops below 30 FPS in any game I lower my setting. If they are over 60 I will keep adding stuff until it hovers around 60. It takes a very sharp set of eyes to notice anything different when it is over 60 FPS. IIRC that is around the rate of speed that human eyes-mind process things.
