c# code

using Godot;

        base._Ready();
        _xrInterface = (OpenXRInterface)XRServer.FindInterface("OpenXR");
        if(_xrInterface != null && _xrInterface.IsInitialized())
        {
            _xrInterface.Connect("session_begun",new Callable(this,"OnStart"));

            GD.Print("OpenXR initialized successfully");

            // Turn off v-sync!
            DisplayServer.WindowSetVsyncMode(DisplayServer.VSyncMode.Disabled);

            var vp = GetViewport();
            // Change our main viewport to output to the HMD
            vp.UseXR = true;

            var camera = GetNode<XRCamera3D>("World/XRPlayer/XRCamera3D");

            if (RenderingServer.GetRenderingDevice() != null){
                GD.Print("render "+vp.UseXR.ToString());
                // vp.VrsMode = Viewport.VrsModeEnum.XR;

            }
            else if ((int)ProjectSettings.GetSetting("xr/openxr/foveation_level") == 0)
                GD.PushWarning("OpenXR: Recommend setting Foveation level to High in Project Settings");

        }
        else
        {
            GD.Print("OpenXR not initialized, please check if your headset is connected");
        }
    }
}

I would like to ask after creating a basic openxr environment in godot4 and opening it in steamvr, it stays on the waiting screen, then I find an error on steamvr , it goes like this

Failed to create sync texture. Ensure application was built using DXGI 1.1 or later (i.e. Call CreateDXGIFactory1).!!!! ComposeLayerProjection: failed to submit view 0: VRCompositorError_SharedTexturesNotSupported

What should I do to fix this?

Steps to reproduce

the code is from offical docs: https://docs.godotengine.org/en/stable/tutorials/xr/setting_up_xr.html

I think you mentioned this one on Discord before. I'm still stumped by it. I suspect it's either a problem with PICOs desktop streaming (though I know others use it on PICO 4) or a problem with the Intel drivers for the Arc graphics card not supporting required features.

If I recall correctly you tried compatibility as well but ran into the issue that the Arcs OpenGL drivers do not support the multiview extension.

The error itself is coming from deep inside the XR runtime, not from Godot.

I'll see if I can get some information from some of my contacts at Pico/Intel but I'm not sure if I'll get an answer quick.
