Hoping that someone here can help.  Just re-loaded Doom3 BFG VR again.
Can happily get the game running.  However I have an issue with the controls.
I wish to move with a mouse and keyboard, just as I would using a monitor.  Right now, I appear to have a "dead zone" for the left/right on my mouse, where the screen just stays still until I've crossed what I guess would equate to my FOV.  
Any idea how to eliminate that dead zone?
