I've tested the demo (on Windows obviously) and the game's screen positions itself on my two monitor setup in the middle of the virtual screen, i.e. one half of the window on each screen. It does have the resolution of my primary monitor and fullscreen is toggled on but of course not active.

I know you've already stated that you will keep the handling as is, but what about a "classic feel" or "rally handling" or "pro (mode)" mutator or something like that which emulates the old behavior?
