The second closed beta phase of The Crew is currently under way and some new information about the PC version of the game has surfaced. According to Ubisoft, the development team targets a 1080p+30fps experience on all platforms (PC, Xbox One and PS4), though the PC will also support 5760*1080 for triple screen set-ups.

The final game will run in 1080p with 30 frames per second on Xbox One, PlayStation 4 and PC, and will support up to 5760*1080p on PC for triple screen set-ups. Right now the team is focusing on providing an optimal experience for all players. You can unlock it in the file you've found, but it may affect the game's performances. Your call.

Note: In order to increase the framerate lock to 60fps, PC gamers will have to edit the "PCScalability.xml" file that is located inside the "C:\Users\Documents\The Crew" folder. Just search for the framerate option and change it from 30 to 60. Changing that option to anything higher than that will not work as that option will reset itself to 60.
