Retail copies of Call of Duty: Ghosts will require a patch on PlayStation 4 so as to repair resolution issues that stem from a configuration problem in the game’s single player campaign. Players who get into the game’s single-player missions without the update would encounter a campaign mode that’s up-scaled from 720p as against the game’s expected 1080p resolution.
In a statement to a website, someone from Activision cited that, “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. 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.”
