"Beautiful. It runs 75fps and smooth as silk on my DK2. One of the best looking demos currently available to show it off. Excellent work. The attention to detail and all of the toggleable options are much appreciated. FWIW, the way I was able to get this to run its best was: * Run the DK2 in Extended Mode * Make DK2 the main display * Ensure the DK2 is the leftmost "monitor" in Windows "Screen Resolution" dialog The positional tracking feels great. It's very nice to lean in and use the head position and dynamic crosshair to hit the "next" button." - Nathan Chase
