When I start swoop race game set swoop a bit too high so I can not hit any obstacle or acceleration pad and the only way I can maneuver swoop is by moving mouse (keyboard doesn't function).
I own a P4 2,4GHz PC with 512MB Ram and Radeon 9000 Graphic Card.
Well, I did notice I can only use the mouse button to accelerate, not the keyboard. For turning the keyboard works though.
I notice that when I press LMB right when the light turns green, I'm high in the sky, but when I wait half a second after it turns green, it goes normally.
