Been watching some videos of the leaked version. And it's honestly not bad. In fairly recent games at least it looks pretty good. Horizon, GTA 5, Forza, TLOU 2, Cyberpunk all look good with it. Didn't really see much of a difference in a cartoonish Cel-shaded game like Borderlands 4 but old games like GTA San Andreas look very cursed with the low poly character models and dated animations. probably best not to use it with those.
It seems like it's best used in newer games that are already going for a realistic look.
