Actually yes it uses the mouse to simulate the head movement and camera views. the mouse buttons and scroll wheel are also used for various functions. Frame rates tend to be in the 60's so it is very fluid. There is a demo version, if you get time maybe have a go.

Just got this game, pretty good it is too. The track editor is brill!
Any chance you guys can develope something to let me use my TrackIR3 Pro with it?

Thanks for a fantastic product...
