can G70/RSX do orthagonal AA?

[BOOMEXPLODE]

I was looking at some screenshots and it struck me that having parts of the image that are anti-aliased and parts that aren't will become a big problem in the future. I don't really understand the reason why current AA methods don't work all the time so can someone explain it to me? Will the next generation parts from ATI and Nvidia fix the problem?

There are a few posts on the forums that say that R520 has new ROP hardware and can multi-sample float buffers. And there are posts that show the new driver options for 7800 GTX that show it capable of AA with alpha textures.

But that's about all you'll get, until NDAs lift, I'd imagine.

Technically r300 and above should also be able to do Alpha test AA of some sort.

I know richard huddy mentioned this in one of his developers optimizations speeches.

Unfortunately i never really see the details how it is exactly done and how it looks as it is not directly supportd by the api and therfore probably a little hacky to implement. I still would like if somebody has any details on this and know how it's done to do some little demo to see how it looks.

Humus where are you? hint hint

The alpha to mask feature has also been available in GeForce hardware for a while now (I think at least since the GF3, but I can't be sure). But since no developers actually use it, it's not really worth noting.

More interesting would be a method to AA alpha textures that is either transparent to the developer, or can be turned on via a simple switch by the developer.

Fast easy good looking Alpha test AA forceable by the user would be a killer feature in my eyes.
