On the merits of what we've seen so far, Battlefield 4 is already set to be a formidable launch window effort from DICE. Our observations so far reveal a clear gap in fidelity between PC and PS4, and again to Xbox One, but sub-pixel break-up aside, based on what we've seen so far, the Microsoft console manages to hold up despite the undeniable, quantifiably worse metrics in terms of both resolution and frame-rate.

Trying to be very unbiased there are things that they both do well over each other. The PS4 has better lighting in my opinion, but certain elements on XBOX One were sharper and clearer. Nothing that anyone is going to give a damn about in terms of a "winner"
