Retail copies of Call of Duty: Ghosts will require a patch on PlayStation 4 in order to fix resolution problems that stem from a "configuration issue" in the game's single player campaign. Players that dive into the game's single-player missions without the update would encounter a campaign mode that is upscaled from 720p as opposed to the game's expected 1080p resolution.

"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."
