    Can someone elucidate what is meant in the ATI CCC with regard to Anti-Aliasing under Filter where one can select Box, Narrow Tent, Wide Tent, & Edge Detection?

    What do these four settings mean? Does one of these settings provide superior performance compared to another? Superior quality?

    Any insight is appreciated.

    I've done some searching on this as well, and though I found little on the subject, what I did find indicates that box is for performance, and edge-detect for quality. I think the vast majority of people, especially with laptop cards, should stay on box. I'm not sure about the tent options, though some people on another forum were saying that they distort the image.

    they are image filters. What they do is have certain effects on the final overall image. Edge Detect sharpens the image by the way it looks for edges and not smooth every pixel being used, this is alot more work for your GPU. Box is the most common filtering method AMD uses and I believe gives you a smaller hit on frames. Its how they image appears on you pixels and sub pixels on your screen, it can make a jagged image smooth by the way it manipulates sub-pixels. Wide tend and narrow tent give the least favourable effects from what I read, it makes things overly blurry and degrades the image in most cases.
