SSAO can be a very muddy specially on moving objects. I don’t miss it in forward : )
Forward pros for us:
1 - MSAA over TAA sharper images and better on moving objects.
2 - performance boost depending what you are doing.
Cons:
1 - Decal support suffers.
2 - No SSS profile for skin.
3 - Begging Epic to fix the first point for at least a year now :).
