Amazing. I always thought that something better than super-sampling had to exist.
I hope this becomes standard on PS3 titles, it's painful seeing all those ragged edges on screen, knowing you have a few gigaflops of processing power sitting there, doing nothing :(
A number of PS3 titles use a technique called morphological anti-aliasing (MLAA) which is more computationally expensive than FXAA but can look better (to art directors and rendering engineers anyways :)) and, because it runs well on the SPUs, it is able to offload the GPU for it to begin on its batch of work.
