Full Cockpit or VR? That is the question

Exactly right. I built my DIY 2DOF Motion Platform with DIY vibration transducers, and custom DYI hardware (pendular yoke, throttles, HOTAS, encoder and button boxes) for about $400. I’m currenty testing the OpenXR Toolkit you referenced, and I do what I can to help its creator with testing and brain storming the features. It has some bugs still, but it’s almost there and hand tracking is already working with an inexpensive Leap Motion controller. Together with motion platform, and of course VR, the experience is mind-blowing. Now, it just needs to be stable and the bugs ironed out and it’s gonna be awesome!
