The PlayStation 4 version of Tomb Raider: Definitive Edition runs at 60 frames per second, executive producer Scot Amos has confirmed.

The Xbox One version is still believed to run at 30FPS, half the speed of the PS4 version.

"Looking here, this is the PS4 version running at 60FPS, again at 1080p," Amos said during a GamesRadar livestream last night. "That's awesome for that to be able to showcase because when you get your hands on it you can feel it."

Amos did not comment on the performance of the Xbox One version.

A report on Rocket Chainsaw, however, claims that "the Xbox One build can technically reach around 45 fps, though this performance is generally only achieved during the most empty, simplest environments. For most of your play, and during action scenes, the Xbox One build will sit on around 30 fps."

The alleged performance gap between the two versions could come as another major blow to Xbox One, which has already seen numerous multiplatform titles performing worse on the system.

Both Call of Duty: Ghosts and Battlefield 4 run at 720p on Xbox One and 1080p/900p respectively on PS4. The PS4 version of Assassin's Creed 4: Black Flag also received a patch increasing its native resolution to 1080p. The game is thought to render at 900p on Xbox One.

Tomb Raider: Definitive Edition launches on PS4 and Xbox One next Friday, January 31.
