Why doesn't AA blur gfx?

[Hiyruu]

I'm quite impressed how hardware AA doesn't blur graphics, or make them look plastic.

well, the cards today use Multi-Sampling, so they wouldn't

but Super-Sampling or "Quincunx" can

Ugh, Quincunx. Bad memories there. I think that technology set back wide acceptance of AA for another generation because so many people thought AA inherently made stuff blurry and less accurate. Anyone remember all those arguments in those threads of yesteryear?

I believe the hardware calculates which pixels are on the edge of geometry.

hmmm super sampling AA shouldn't make things blurry if done correctly (meaning only sampling the correct places not like quincux which samples neighbors for generating a pixel though only half them are for the actual pixel). Supersampling can work with the extent of acting as well like AF boosting texture quality.

Can anyone explain why supersampling works on alpha tested textures while multisampling does not?
