Thief outputs at a native 1080p resolution on PlayStation 4 and a native 900p resolution on Xbox One, Square Enix has confirmed to Eurogamer.
Both versions run at 30 frames per second.
Thief is the latest multiplatform next-generation game to perform best on PS4, following in the footsteps of the likes of Infinity Ward's Call of Duty: Ghosts. This week Kojima Productions confirmed that Metal Gear Solid: Ground Zeroes would output on PS4 at 1080p and on Xbox One at 720p.
The difference in resolution with Thief isn't quite as stark as it is with Call of Duty and Metal Gear Solid. Thief's resolution on Xbox One mirror's that of Assassin's Creed 4 and Ryse, both of which output at 900p and 30fps on Xbox One.
"You really need good eyes to see the difference," game director Nicolas Cantin told Eurogamer of the resolution difference between PS4 and Xbox One, before insisting the Xbox One version "is as good as the PS4 version".
For Cantin, and others on the design team, the Xbox One version's resolution "doesn't make much of a difference".
"As developers, no," he continued. "As engineers, yeah. The engineers, for sure. But for us, as creative director or art director or level designer, we gave the same data. After that it's a more technological aspect of the game. The engineers have to manage that."
For Cantin, the difference is more pronounced when you compare the current-gen versions of the stealth action game to the next-gen versions - as you'd expect.
"The immersion is more [on next-gen]," he said. "We put more detail in, more special effects. But at the same time, we kept the same gameplay experience with the current-gen and the next-gen versions."
Digital Foundry will be ready and waiting when Thief goes on sale next week.
