Add TAA as an AA option.

FXAA doesn't work very well even at 2560x1440. That's my suggestion.

SMAA might also work, I think ue3 uses a deferred renderer so MSAA wont work at all so I think TAA is the best post process AA option to remove all the jaggies.

No idea how hard it may or may not be to implement this tech into UE3 though, but I think a lot of people myself included would greatly appreciate it.

inb4 the "TAA sucks" comments, I used to hate it too until I realized how great it was at eliminating temporal aliasing. + at 1440p it's not as blurry as it was during my 1080p days. But that's just my opinion, it'd be great if SMLAA/SMAA could be added as an extra option on top of adding TAA.
