Did they actually fix the models? Or just reduce graphics options for better performance? From what I had read, a lot of the models were way higher poly than they should have been, in some cases maybe just exports from zbrush. Game performed way worse than it should have for how it looked, especially compared to Nioh 2 running on (presumably) the same engine.
For the record I played on PC, and it was pretty rough around launch time. Got through the main game, I think, or just before the end, and decided to put it on hold hoping they'd fix it along with the DLC.
