No, it’s slow because software developers are still scarce today. All we need is some code to turn on the displays - the USB packet captures are already on the issue tracker for someone who wants to work on this. Maybe some day I will get to it myself. Or maybe someone can toss some thousands of dollars in the direction of OpenHMD devs so they can presumably quit their day jobs. Otherwise, the OpenHMD devs seem to be slowly gaining interest in Pimax headsets.
No, definitely NOT the kind of thing WINE works with. No compatibility layers exist for such things at all like PiTool.
