NVIDIA Developing Subpixel Reconstruction Antialiasing to Compete with MLAA

[RavenXXX2]

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.

Where SRAA defers from MLAA is that the new algorithm can better respect geometric boundaries and has a 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," claims NVIDIA.

Will this also be Vaseline-o-vision?

Maybe it will stop the moaning now that both teams will be able to do it.

Bet it won't get enabled on the 400 series and lower, prime thing to try and sell shiny new 500 series to us 400 lowlifes

You'll get the usuals gushing over it as if it's the next big thing.

Probably 400 series and higher, makes more sense because they still produce 460's.

pretty interesting tech

Will see how this turns out but if it's anything like MLAA blurry vision, I won't be using it.
