Meta Quest 3 PC Link continually freezing & I can't use WiFi Airlink
I recently purchased a Meta Quest 3 to use with Emulate3D for machine VR simulations. I'm connecting the headset to my PC using the official Meta Link cable and the Meta Horizon Link app. I DO NOT want to use WiFi to connect my headset and PC because of the security risks and because my PC is much stronger and can run large simulations much better.
The headset initially works perfectly. After connecting through Link, I can access the Link dashboard, view my PC desktop in VR, launch Emulate3D, and enter a live VR simulation. Everything runs normally at first and I can walk around the model and interact with it without any issues.
The problem is that after a few minutes, the headset display freezes completely. The image inside the headset becomes locked on the last rendered frame, and when I move my head around, the final frame stays where it was and the rest of my view is black and pixelated. The controllers also stop responding inside the headset. I have determined that Emulate3D itself is not the problem because this same error happens after a few minutes of just sitting in the Link dashboard without doing anything.
What's interesting is that Emulate3D itself does not crash. The simulation continues running normally on the PC. More importantly, the Emulate3D VR viewer on the desktop continues to respond to both headset and controller movement after the headset display freezes. If I move the headset around while watching the monitor, the camera view inside Emulate3D still updates correctly. This makes me think that the PC is still receiving tracking information from the headset and controllers, but the video stream being sent back to the headset has stopped working.
Within the Horizon Link app, it alternates between these two messages: "Your computer doesn't meet the updated minimum specifications, which can lead to poor experience in VR" and "You won't be able to use the link feature, as your hardware is incompatible with it". Which are both frustrating/confusing because I have literally been able to use the Link feature.
I also get this notification when I turn my headset off while the cable is still plugged in: "Link stopped working. If this problem persists, there may be an issue with your cable."
I ran the built-in Link cable test in Meta Horizon Link and it reports a compatible USB 3 connection with approximately 2.7 Gbps of bandwidth so I don't think it's a cable issue either.
My only fix right now is restarting my PC and headset and connecting them when it turns back on. The link works for a few minutes then stops. Twice it has also gotten stuck on the purple loading page to go into the Link dashboard. Sometimes, instead of the frozen frame and pixels, it also just goes into passthrough mode and I can't do anything, not even with the controller buttons.
Are there any fixes to this or different connection apps I could download to connect to my PC. I know there's SteamLink, but like I said I only want a tethered PC connection.
Any suggestions appreciated, thanks!
