I’d like to know as well. I’m currently thinking about replacing my Quest 2 with the Neo 3 Link, because the reviews are excellent, and it seems to be the perfect HMD for PCVR. The DisplayPort connection and the superior display clarity is what sells it to me.
Weird that it’s not working with VorpX. It’s SteamVR compatible, so VorpX should theoretically see a SteamVR HMD. Did you try the other options, like OpenXR? IDK, just speculating here…
