TEEROY, I don't recall any degradation of the image at the edges of the screen with the HD demo that Tom Milks had.
As Kelly has said the old Buick film was supplied to VirTra and was not HD. The new Buick promotion was filmed specifically for the Immersa-Dome and in HD.
As far a using a controller in the Immersa-Dome, YES, it can be configured for all types of control. Steering wheel and foot pedals. or for airplane stick, rudder and throttle. or just the simple joystick.
I will have to pick up a June issue of P M and see if I can tell what it is.
