Quest Pro Passthrough lag/latency/low framerate over Oculus Link cable
The Quest Pro passthrough video feed lags considerably when entering Play mode in Unity and using the Link cable. Virtual objects render at > 72 FPS (reported in Stats window), but the video underlay...
Have you managed to solve this in any way please? It's horrible to work on anything through Unity!
The passthrough performance for me has been better in recent days. I'm not exactly sure what fixed it, but I think it might have been these things:
1) The quality of the USB-C cable is crucial. If you're using a low quality USB-C cable, it won't be able to handle the bandwidth of the passthrough video feed.
2) The kind of USB-C port on your computer might(?) be important. I recently learned that not all USB-C ports are created equal! Essentially, you'll want to look to see if your computer has a USB-C Thunderbolt type of port. These ports are capable of 40 GB/s compared to the 20 GB/s of typical USB-C ports.

Although the passthrough video framerate has been better is recent days for me, it's still not as good as when I'm running natively on the headset. But hopefully these tips may help you.
