The 30fps vs 60fps debate always rages hard when it comes to racing games and no more so than when on the PC. And with The Crew Beta being at 30fps and words being banded about that it is going to be locked at this it's no surprise that people have been venting their upset and disappointment with this via twitter, comments on site articles and of course via the official Beta forums.
So it may be of a little comfort to see that a post by an Ubisoft representative has stated that they are "aiming at a 60 FPS on PC for the launch of the game". We will need to wait and see if they make this target or at least make it optional for the PC Master Race to unlock themselves without causing too many issues with the game and it's in-game scenes.
