Just to explain motivation here.
I'm not a fan of the ghosting of TAA, but i think most people would say it looks best in static screenshots because of the sharpening inside of it.
So i wanted something that had that crispy look, but more configurable, so I wrote an implementation based on https://gpuopen.com/fidelityfx-cas/
Currently it's always on when SMAA is active, so you may want to throw in a switch for it.
give it a shot, i think it looks quite nice.
examples:
NO AA
TAA
SMAA with CAS
