[UPDATE] Digital Foundry has now posted its performance analysis for Advanced Warfare's multiplayer mode, finding that both the Xbox One and PS4 versions of the game are able to achieve 60fps with only rare instances of dipping below that mark.

The original story is below.

According to an in-depth performance analysis test done by Eurogamer's Digital Foundry, the Xbox One version of Call of Duty: Advanced Warfare's single-player campaign runs at a smoother frame rate overall than the PlayStation 4 iteration. This comes down to the PS4 version's 1080p visuals, Digital Foundry writes.

"The PS4 version's constant 1080p output comes at a price," reads a line from the report.

"We catch dips between the 50-60fps lines during battles through Seoul's streets--with drops to the high 40s caught when throwing the 'threat' grenades to scan the area for enemies," it goes on. "Even in perfectly matched scenes, the Xbox One's performance tends to hold at a perfect 60fps by comparison."

Earlier this week, Advanced Warfare developer Sledgehammer Games revealed that, just like 2013's Call of Duty: Ghosts before it, the game runs in 1080p on PS4 and something less on Xbox One.

Digital Foundry's report runs counter to what Sledgehammer co-founder Michael Condrey said recently, when he explained that both the Xbox One and PS4 versions of Advanced Warfare run at a "rock solid" 60fps.

In August this year, Microsoft's gaming boss, Phil Spencer, said frame rate is "significantly more important" to gameplay than resolution.
