A PC will always have the potential to look way better than any current gen console, no matter how powerful the console is supposed to be. From what I understand, the One X is equivalent to a mid-range PC.
Not exactly sure what you mean here to be honest. We can only get as much out of the One X if the devs of a game are up to the task and have the know how, and it's still only comparable to a mid-range PC from what I understand.
Agreed doubt you’d see much at 1080, aside from fps.
I will say this game is optimized quite well for a PC port I’m currently running (2) 2560x1440 screens using SRWE in a 7680x1440 resolution getting high fps.
Waiting on my third dead pixel screen to return from exchange.
