Thanks, but it seems that when sensitivity is changed, it only affects the horizontal speed while keeping the vertical speed unchanged, and that makes the mouse move in a strange way. Is there anything wrong? Ehh... I tried some other games, it seems that this problem only happens in one game....

I'm feeling that the mouse speed is too slow.... Could anyone please tell me how to modify it?
