The dev is talking about OpenXR support on the headset itself (Android), not on the PC side. I don’t know anyone who has information on that side of the Crystal. There is no OpenXR Compliance submission from Pimax (these are publicly listed on the Khronos website: Conformant Products - The Khronos Group Inc). Maybe that dev has contacted Pimax to inquire what the OpenXR support on the headset side will be like (and what extensions it will support).
OpenXR support on PC side (like PimaxXR) isn’t relevant to Virtual Desktop. There isn’t anything I can contribute AFAIK.
And on that front, I’m not sure what extensions Virtual Desktop could possibly need that isn’t core spec (basic functionality). Since Virtual Desktop is closed-source, we can’t know (and I have no intention to go reverse-engineer their package).
They might release without official compliance, which isn’t illegal or anything, I think they just can’t use the OpenXR logo or something like that. PimaxXR isn’t officially compliant either, doesn’t prevent to run all OpenXR games out there (to my knowledge).
The compliance results are nice to see exactly the capabilities without needed to buy the device
