I am trying to use XR_FB_passthrough extension on Quest 3 tethered to PC.
Here (OpenXR Runtime Extension Support Report) it claims this is supported on “Meta (PC) Developer Mode”, but when I print supported extensions on application startup I don’t see this extension supported.
What are possible reasons for this? Could it be the OpenXR loader being old? Or the runtime? Or is does Meta (PC) Developer Mode mean something else?
