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.
