Meta Quest 3 - Quest Link drops to 20fps

[ravan56]

I'm fighting with severe framedrops when using quest link and UE5 for a VR project.

I startet the Oculus debug tool and the performance graphic says that my frames are dropping from 80 to 20 when starting the VR preview.

How can I mitigate this problem? Does anyone has a tipp or knowings about this misbehaviour?

I tried the following:

- disable Hardware accelerated graphics in windows

- all graphics drivers are up to date

- rendertime in UE5 is 5-6ms, still frames in VR headset is dropping to 20fps

- App Motion to Photon Latency jumps to around 70ms

- I tried with a USB Link cable on Usb 3.0 port (all drivers are installed and up to date)

- I tried with Air Link, still the same

My system: AMD Ryzen 9 3900X, 32 GB Ram, MSI MEG X570 UNIFY, MSI RTX 4070 Ti Ventus 3X, Win 11

Thanks for your precious help.
