Sony's platform has the technical edge, developer Infinity Ward confirm this morning, after rumours started circulating last week.
Last week, rumours began circulating that the Xbox One version of Call of Duty: Ghosts is being rendered at 1280x720 (720p), while the PlayStation 4 version is using the higher standard of 1920x1080 (1080p.)
Mark Rubin, Executive Producer at Infinity Ward (the game's developer), released a statement via Twitter this morning that addressed the rumours head on.
"Hey, been on the road last couple weeks so haven't had a chance to update," Rubin's message (on the TwitLonger service) began. "[I] wanted to confirm that for Xbox One we're 1080p upscaled from 720p."
Upscaling, if you're unfamiliar with the term, means that the Xbox One is rendering at 720p and then a separate process is used to convert that signal to a higher resolution - a scenario that generally results in an inferior image to one that's rendered at the output resolution from the start.
"We're native 1080p on PS4," Rubin added, confirming that the PlayStation 4 version has the technical advantage for Ghosts, and is able to output 125% more pixels with their engine. Rubin concluded by stating "we optimized each console to hit 60 FPS and the game looks great on both."
Information regarding rendering resolutions on current-generation versions of the game was not disclosed.
