Subpixel Reconstruction Antialiasing

Subpixel Reconstruction Antialiasing (SRAA) combines single-pixel (1x) shading with subpixel visibility to create antialiased images without increasing the shading cost. SRAA targets deferred-shading renderers, which cannot use multisample antialiasing. SRAA operates as a post-process on a rendered image with superresolution depth and normal buffers, so it can be incorporated into an existing renderer without modifying the shaders. In this way SRAA resembles Morphological Antialiasing (MLAA), but the new algorithm can better respect geometric boundaries and has fixed runtime independent of scene and image complexity. SRAA benefits shading-bound applications. For example, our implementation evaluates SRAA in 1.8 ms (1280x720) to yield antialiasing quality comparable to 4-16x shading. Thus SRAA would produce a net speedup over supersampling for applications that spend 1 ms or more on shading; for comparison, most modern games spend 5-10 ms shading. We also describe simplifications that increase performance by reducing quality.

So less blurriness and better performance than MLAA. Unless I'm reading this wrong.

Yes, looking forward to it.

i guess mlaa/sraa are the only things that can help for those games where developer just doesn't want to give aa support...due to console porting.

Heh, I didn't even think about the ports...that will be nice.

I LOVE THE FUTURE!!

Thank you ATi for introducing MLAA, thus forcing nVidia to follow suit and come out with their own version. Once again, competition equals win for us consumers!

/tRollo baiting.

I'm sure it will be identical to mlaa.

Most likely, yeah. But which card will be able to do this new SRAA feature?

So.. is this coming in the next driver rev or what?

No clue, I assume all the 500 series at least.

The article has a date of Feb 2011 over the download placeholder, so hopefully.

Also hoping it's 400 and 500 series Fermis, not just the 500. Should be...
