The PlayStation 4 version of Call of Duty: Ghosts runs in 1080p, but it requires a day-one patch to get the single-player campaign from 720p to the higher resolution, an Activision representative confirmed to Polygon today.
The problem, which was initially reported by Eurogamer, is that the campaign in retail copies of the PS4 version runs in 720p instead of 1080p. Ghosts developer Infinity Ward announced last month that the entire game runs in 1080p on PS4 and 720p on Xbox One — a gap that, according to executive producer Mark Rubin, wasn't attributable to anything specific with Microsoft's console.
In a statement given to Polygon today, an Activision representative reaffirmed that the whole PS4 game runs in 1080p and said the 720p campaign on PS4 is a mistake caused by a "configuration error" in the retail disc version.
The rep continued, "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."
Call of Duty: Ghosts will be available on PS4 alongside the console's North American launch Nov. 15.
