But in a recent screenshot most likely sourced from Nvidia's GeForce Kepler press-deck, the company compares an ambiguously unrevealed anti-aliasing technique with 8x MSAA, in which it appears to give noticeably superior image quality. Some analysts have suggested that the unrevealed technique could be a heavily optimized version of Temporal Anti-Aliasing, a very compute-heavy technique that involves deriving a high resolution (see: larger than the output image) "temporal intensity function" from object attributes within the frame and then applying an "averaging filter" to compute the final anti-aliased image.
In perspective, "temporal aliasing" is the result of the sample rate (i.e. number of frames per second) of a scene being too low compared to the transformation speed of objects inside of the scene. In other words, this causes objects to appear to "jump" or appear at a location instead of giving the impression of smoothly moving towards them.
