The two versions look nearly identical. Viewing the Xbox One release next to the PS4 ,
I had difficulty telling them apart. It's possible that the PS4 version looked somewhat sharper, but that may have just been my imagination after confirming the hard resolution difference.
The Xbox One release's framerate was far more noticeable. As mentioned in the initial review, Call of Duty: Ghosts suffers from consistent framerate drops on the PS4, especially during multiplayer when action got especially hectic. The Xbox One version suffered no such drops, maintaining a steady 60 frames per second throughout.
Character customization, maps, dynamic events, weapons, gametypes, and constant 60fps multiplayer framerates are ubiquitous across current- and next-gen platforms. The biggest variations between platforms falls upon visuals and player counts.
On the current-gen versions Ghosts looks nearly identical, though I did encounter occasional framerate issues during the single-player campaign on PS3 and PS4, whereas my time with the Xbox One version was stable throughout.
