NVIDIA Developing Subpixel Reconstruction Antialiasing to Compete with MLAA

NVIDIA is developing its own antialiasing (AA) technology to rival morphological antialiasing (MLAA). The subpixel reconstruction antialiasing (SRAA) NVIDIA is currently conducting research on aims to provide better image quality with minimal performance penalty. It "combines single-pixel (1x) shading with subpixel visibility to create antialiased images without increasing the shading cost," as NVIDIA puts it in its research abstract. SRAA is suited for rendering engines that don't use multisample antialiasing (MSAA) since they use deferred shading. For such renderers, SRAA works as a post-processing layer, just like MLAA.

Neat. I wonder what kind of quality difference there is between SRAA and MLAA.

At this point I don't even understand MLAA...
What does all this mumbo jumbo do? D:

MSAA and MLAA are to different types of AA (Anti-Ailising) the software that eliminates "Zaggies"

MLAA is a way to get rid of "Zaggies" just like MSAA but MLAA does it without hurting FPS as much as MSAA does.

I prefer MSAA because it has edge detection and it just does it better and sharper. MLAA is evolving very nicely but sometimes objects get blurred cause to me, in my opinion is that MLAA just blurs the edges to eliminate Zaggies while MSAA actually uses edge detection to smooth them out. Now don't get me wrong MLAA is good but I notice more blur in MLAA than MSAA. The PS3 uses MLAA where as the 360 uses up to 4x MSAA.

The best thing to do is use 4xAA and MLAA together for a really good picture or if your GPU has the horse power just use 8x MSAA. AMD HD6000 cards have MLAA and you can turn it on or off or use it with MSAA.

hopes this helps

Thanks, that helps alot.
I never understood the difference between the types of AAs, but that makes alot more sense.
Now I understand how they used MLAA in GoW3.
hmm, my vid card is just a HD4600s. Seems like I'll need to upgrade in the upcoming future to see these techs in practice.

Thanks again for the detailed reply!

It's "jaggy", btw.

Jagged lines.

The PS3's use of MLAA is very different to the MLAA usable with ATI cards, though.
