Squishyderpy, I read your review and am a little confused by the graphic-based complaints you had. I also have a 4K monitor and didn't notice any of the issues you mentioned. My game is not in a small box, surrounded by black bars like you describe. This is the full screen for me, uncut:
The selection space for clicking doesn't seem especially small to me; I have no problem clicking the dialogue option I want. My settings aren't set to max and I don't think it looks bad in general, although for me it would depend on what exactly I'm looking at. For instance, the models roaming around aren't nearly as details as those during a conversation.
My point in this post isn't to say you're wrong or right or anything like that. I'm just wondering if you have some setting somewhere causing some of the more frustrating visual aspects that you mentioned. The most surprising thing to me was the black bars / small box. I'm not sure what causes that, but I don't see what you've described. I can only assume there's a setting difference at fault somewhere.
