XR Elite PC VR Unity low resolution

[Anonymous2585]

Hi,

I have an XR Elite that I use for a PC VR app streaming with USB C cable.

My issue is that whatever the resolution set in VBS Graphics settings, my Unity app (editor or a build) runs at a low resolution of 1440x1440px per eye.
In SteamVR Home, I can see the resolution correspond to the VBS setting when I change it (= no issue in SteamVR Home).

Environment:
- Windows 10 22H2 up to date
- Vive Business Streaming 2.0.12
- SteamVR 2.8.6
- Unity 2022.3.51f1 or 6000.3.23f1 with OpenXR 1.13.0 plugin
- DirectX 11

Having the Vive OpenXR plugin or not in the Unity project doesn't change anything.

Here are the Unity OpenXR startup logs, where you see the requested resolution to 1440x1400 instead of 3072x3072 per eye (VBS setting set to Ultra):

Full logs attached to the post.

Maybe I missed a setting somewhere, or is it a known bug?
