Anti Aliasing options are definitely
BAD for this demo. I didn't even notice it was raining outside until I disabled TAA. The blurriness is so bad, that the rain gets blurred out to the point that it isn't there anymore (even at 4k). Also, blood and wet surfaces are not shiny anymore, and that with the lack of rain destroys the atmosphere.
FXAA + TAA (or TAA alone):
SMAA (or No AA or FXAA):
The rain for me, is what made all the difference to create the atmosphere. This is obviously just a picture, but actually seeing the rain outside the window makes a huge difference.
I tried Reshade with LumaSharpening (and later with AdaptiveSharpening) but neither are strong enough to bring back the rain or the shiny surfaces.
I don't mind the blurriness either, but missing components of the atmosphere that were clearly meant to be there just because TAA eliminates them...?
Of course, SMAA or FXAA don't work at all. Jagged edges everywhere and they are very distracting.
I really don't think CAPCOM will fix this for the final release, but I really hope they do.
