It seems that Nvidia is researching a new antialiasing technology to compete with AMD's MLAA (Morphological Anti-Aliasing). Nvidia has published the following abstract from its research: "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.
