PS4/Xbox One versions of Tomb Raider made in different studios

The PlayStation 4 and Xbox One versions of Tomb Raider: Definitive Edition were made by different studios.

That's according to a note on Nixxes' website, which claims that the developer had a hand in the PS4 version of the upcoming adventure port.

"Nixxes Software is proud to announce that it has been working on the PlayStation 4 version for the recent announced Tomb Raider: Definitive Edition," read the note.

Nixxes goes on to claim that United Front Games, the guys behind Sleeping Dogs, worked on the Xbox One version.

"In addition to converting the game to PlayStation 4, Nixxes Software provided support to United Front Games, the developer responsible for the Xbox One version of the game."

Yesterday it was revealed that Tomb Raider: Definitive Edition ran at 60 frames-per-second on PS4 and 30 frames-per-second on the Xbox One.

Square Enix has refrained from commenting on the issue but have different studios work on the ports would explain the discrepancy in frame rate.
