There had been rumours flying around the Call of Duty: Ghosts wasn't running in full 1080p on Xbox One, while the PlayStation 4 was happily running the game in full HD. Well, it turns out that there's no smoke without fire, and that the Xbox One version of Ghosts does in fact only run at 720p, with the game upscaled to 1080p. Both versions have been optimised to run at 60 FPS.
Activision's Mark Rubin confirmed the news that: "for Xbox One we're 1080p upscaled from 720p. And, we're native 1080p on PS4. We optimized each console to hit 60 FPS and the game looks great on both. Still on the road, but glad to see the great reception to Extinction. Can't wait for next week's launch."
