hi,
i have the Vive Focus Vision VR headset, it does have eye-tracking, but it doesnt work for DCS's ET-QV. i asked around on the VIVERSE discord server if they could help, they say that ED/DCS needs to support this OpenXR Extension https://registry.khronos.org/OpenXR/specs/1.0/html/xrspec.html#XR_EXT_eye_gaze_interaction for the Focus Vision to give/feed Eye-Tracking data, i know that my headset is not giving any ET data because the ET IR-Lights wont turn on when running/opening DCS. i have made some screenshots of the chat about it:
i dont know alot (or anything really) about OpenXR layers/extensions....
i think/assume the vive focus 3 (with ET module) and the vive XR Elite (will) have similar problems/requirements.
with some work and searching i did manage to get QV itself working, but no ET-QV.
im running the Focus Vision with a DP connection via the Wired Streaming Kit (DP), VIVE Hub and SteamVR
