Personally, where monsters and world are concerned, I feel that XV actually does a lot to make up for its technical shortcomings on console. Enemy design is fantastic. Really captured that blend of realism and fantasy that Versus was striving for without taking it to stupid extremes like some of Tabata's less attractive changes to the game did. The locations outside of the dusty and frankly mundane smaller settlements are also strikingly good, Lestallum and Insomnia being particularly impressive to me, and the Astral shard cuts a brilliant figure across Duscae's skyline.
If they aren't able to improve the image quality much more, it'll be disappointing but I'll be able to get through it thanks to that art direction. I can definitely understand why it's so important for the game to back up its art with tech, though. It would be a shame not to show off those assets in the best way possible.
