It's supposed to trick the game into thinking it has a G27 plugged in, with pedals, shifter, everything. The FFB then gets sent as if it was a G27. Probably not that much of a big deal as with OSW we can tune the settings in Simucube, they will still have an effect. V Rally picks up all my stuff but doesn't function properly when the FFB kicks in. It stutters, frames get drawn out way too long and then everything speeds up, like a rubber band being pulled and then let go. I take off the wheel and use the keyboard, and everything works as it should. They're NEARLY there with supporting higher end devices, but still not quite. I think the Gimx will be a handy tool for those of us that want to still experience these mostly off road titles without having to own a whole other wheel setup.
