The Steam translation layer is very good, but you get the wrong glyphs on screen, it can't generate trigger haptic feedback if the game isn't providing it in the first place, and I find some old games really just don't work very well at all with a PS controller. ACC was okay with a PS controller, like FM it works at a "bare minimum" kind of level, rather than the "best in class" level of Crew Motorsport. The Crew Motorsport's sensitivity adjustments and option of a direct mode for truly hardcore players are better than any controller adjustments I've seen in any other driving game. Forza feels completely sluggish to me now by comparison.
Super resolution is one of the DLSS features, as is frame generation. As it only specifically mentions super resolution, I assume that is the only DLSS feature AC EVO will be supporting on day 1. The new transformer model does look like a stunning improvement, but I think we might have to wait till Jan 30th for that.
