Becuase MSAA is cool and "Real AA" don't you know? Why need anything more than compromised Geometry AA? >_> Deus Ex though. Looks like the pre-AA input has some kind of heavy sharpening pass on it however.(Or unsharpen mask?)_ Probably doesn't help. At least it doesn't look as bad as the sharpening that was added to UE4 TAA in the last year. Which solves none of it's problems and actually makes some aliasing more apparent. Also makes certain parts of the image really "blotchy" looking like Doom's sharpening. I thought it was the TAA at first, but the effect disappeared completely with sharpening disabled in Doom.
