Infinity Ward has announced the resolutions of the next-gen versions of Call of Duty: Ghosts.
Confirming previous rumours, the Xbox One version of the upcoming shooter runs natively at 720p. The PlayStation 4 version runs natively at 1080p.
Speaking on Twitter, Infinity Ward executive producer Mark Rubin said the Xbox One version is "upscaled" from 720p to 1080p.
The tweet in full: "Hey, been on the road last couple weeks so haven't had a chance to update, but wanted to confirm 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."
The news is a blow to Microsoft, which has battled concern about the power of the Xbox One compared to the PlayStation 4 since the specifications for both consoles were announced, and invested heavily in exclusive Call of Duty DLC. It also appears Infinity Ward failed to meet the performance targets it had hoped to hit at E3 in June, when Rubin told Eurogamer Ghosts would output at 1080p and 60 frames per second on both consoles.
