No crashes or issues at all here. Game works quite well and with a higher FOV it looks pretty damn good as well.
The UI is definitely a straight console port, but honestly I think it works pretty well. Since it was designed around four points of a stick it also feels designed around WASD. It's quick and easy to access and control for the most part, only the level-up menu felt cumbersome to me.
The game so far seems much better than Oblivion already, but I'm still very early on.
