"Call of Duty: Ghosts runs natively at 1080p on the PlayStation 4. There was a configuration issue in the retail version on single player mode only," Activision told Joystiq in a statement. "This has been addressed with a day one software update. People will be able to download the day one update when PlayStation 4 launches in their territory and play at native 1080p."
Infinity Ward Executive Producer Mark Rubin said in late October that the game runs at a native resolution of 1080p (1920x1080) on PS4 and that the developer "optimized each console to hit 60 FPS and the game looks great on both."
