That’s awesome! I’m not an advanced engine/graphics programmer so I spent weeks trying to figure out how to get it in unreal.
I and others sensitive to temporal blur desperately need other options in Unreal and FXAA is burriest non-temporal AA.
EDIT: I compile from source, I had to replace the AreaTex and SearchTex and also found no way to take off the temporal frame blending from the commit.
