Mudrunner ignores joystick input when keys are pressed. This is a problem for anyone that uses a game board anyone that ramaps any joystick buttons to keys.
I use a G13 so I can mouse view with my right hand and drive with the left. If I press a key my truck ignores the joystick and stops driving.
Why do all these games need to switch controls? Just accepts controlls from joystick game controller and keyboard all at once. At the very least joystick and keyboard should should work together on PC.
