To me it was immersive af, except the Johnny Silverhand levels, even though I played on a weaker rig that I have currently and the framerate wasn't great. What I did was focus on the story and largely ditch the open world aspect, since I hadn't been fond of this type of games for some time anyway. I played it almost a year ago and don't remember it notoriously crashing, or at all tbh, but maybe I was just lucky.

I'm very curious about Phantom Liberty, although being a patient gamer, I'll probably wait a bit before buying it to see if it's any good.
