When I try to move forward pressing "W" on keyboard, or any other direction, the frame drop to 0 and stops. But it moves fine when I use ";" and do the auto-run or get on the car that some one else's driving. So I don't think it's CPU nor Graphic Board which are ok; Core i7 3.4GHz and GeForce GTX980. Any body have any clue? thanks in advance.
