4xAA already does that .
And graphically , I don't think it'll be better than Crysis .. around the same , if not worse . But that doesn't really matter . Graphics are already nothing short of INSANELY photorealistic in Crysis already ... no need to make it better , maybe physics , but not graphics themselves . It's time game developers actually concentrate on the game itself , not the graphics .
