If [code]true[/code], OpenXR will manage the depth buffer and use the depth buffer for advanced reprojection provided this is supported by the XR runtime. Note that some rendering features in Godot can't be used with this feature.

Specify the view configuration with which to configure OpenXR setting up either Mono or Stereo rendering.
