Game looks great and runs well for me (granted I'm using an old 1080ti so medium quality, 35 FPs overworld, 60+ interiors/etc - I don't really care at all, 30 fps is fine for me, but also haven't tried tinkering with settings/upscaler to get better performance at all).
Love that it's still Oblivion under the hood, that was my biggest concern. Granted I'm only level 5, but I'm really optimistic at this present moment. Some weird jank, like some new NPCs look amazing, others look questionable and sometimes their animations when talking or expressing are hilarious. Haven't had nearly as much time to play as I'd like, but easing along! Love that lockpicking, athletics, acrobatics, etc are all still here and well.
It's definitely more muted than the original with the bloom to the max, but Fallout 3 is a stretch of a comparison..
