The OpenXR Mock Runtime tests tried to use D3D11 instead of D3D12 when the unity player is configured to use D3D12.
According to [XRF-323 [SPIKE] D3D12 OpenXR Mock Runtime support - Part 1|https://jira.unity3d.com/browse/XRF-323], D3D12 now supports OpenXR Mock Runtime. However, when we run the xr.xrautomated graphics test on MockRuntime against D3D12, in the UnityLog.txt, it shows:
{code:java}
Dedicated video D3D11 device creation failed (error: 0x887a0004). This device is used specifically for video decoding, we will use software video decoding instead.{code}
Which I think its trying to use the D3D11 instead of D3D12.
