I can "turn down" the settings, but I shouldnt have to on a 13900k w/a 4090 Strix. They still have something fucky going on at ultra high, as I shouldnt be able to run CP2077 with ultra realism mods at a good 50-60 FPS, and this down at 40 something. Its dumb, but.. I didnt play an hour either. Its not just a low frame rate, its.. like you said, some kind fo stutter. Ill be in town at that lower, sluggish FPS, and then be in a dungeon running smooth. If I had to formulate a theory, its where they have a bajillion different phases interconnecting so people can see each other.
The horse being able to go Nascar in town is definitely nice, and the zoomed out screen is really nice. But theres some kind of bug with the horse where if my mouse is too far away from the horse, he'll go ultra retard slow until I bring the mouse closer to him and then he goes nascar. Its an annoying workaround and I shouldnt have to.
The basics of the game seem to be headed in the right direction, but I really do miss the polish that Blizzard used to have.
