Yeah, that's what I did. Windows says that the resolution is set to 4K and I set New Vegas to 4K in the options. Do you know of any games that have their visuals vastly improved by the 4K setting? For instance, I just ran the Witcher 3 at 1440p and 4K, it looked nice, but I'm not so sure about the difference between that and 1080p. It also stuttered a little, so I had to lower some of the settings. As an additional question of mine: I have a GTX 1070 and an i7 7700k (both at factory settings). How well do you think my PC would perform across the board with higher resolutions and/or settings? Do you have any tips or recommendations? I think you should go for medium settings on 4K with a GTX 1070
