Jesus Christ, trying to figure out what TRAA is (presumably an anti-aliasing algorithm) and how it works and it's entirely impossible to google. | |||||||||||||||||

The free Google AI mode got it for me on the first try by just pasting in the comment and asking what TRAA was in that context. | |||||||||||||||||

TRAA basically works by using a history buffer, for example using the last couple of frames, all jittered a little bit to compute the pixel. There's still ghosting and smearing that can happen though because of this technique, so you have methods to counteract like subpixel correction where u increase temporal alpha when velocity is subpixel, but that can introduce some artifacts as well. There's also SMAA T2x which the pmndrs team is planning on integrating into their postprocessing package[0]. This cryengine3 slideshow gives a nice overview of antialiasing methods if you're interested: http://iryoku.com/aacourse/downloads/13-Anti-Aliasing-Method...
