    1111So it appears that AirLink is introducing the glitches and they happen with both the OpenXR API and SteamVR API.

    13 These tests were all with vive.cgl.ucsf.edu, Windows 10, Quadro P6000, ethernet to RBVIVR router, no wifi connection with computer, with Quest 2 headset using AirLink on RBVIVR wifi 6 showing  signal strength "excellent" at 5 GHz and 573Mbps send and receive speeds.

     15If I lower the Quest AirLink bit rate to 20 Mbps or 10 Mbps dynamic the glitching goes away although visual quality is a bit worse.  At 30 Mbps I start getting glitches again.  The bit rate setting is in the Quest headset when connected by AirLink, the icon bar has a facemask icon on the left that allows setting bit rate.  Maybe this old Windows 10 machine is too slow at compressing the video.  Should test the new Windows 11 Nvidia 3070 VR machine to see if it exhibits the same glitching.
