DLSS 5 is not meant to be slapped on like a filter but to be something the devs use as another way to craft their desired visual style.

OP's video is interesting because it shows what it does to a game if applied several times. But even once makes the characters look weird because it goes so hard against the original art style.

DLSS 5 as it is seems way more suited for something like say Resident Evil that is in a "realistic but not quite" territory by default.
