    Is there any update on the progress on this? Support for multiple GPUs in dx12 while using VR is a very important feature for me.

    DirectX 12 may be considered "unsupported" as described in this bug report, but it is listed as "On Track" for 5.4's release this month. DirectX 12 should work with OpenVR if it will be considered stable for release. This is the stack trace I get for this error:

    0x00007FF66A9BD405 (ff) RenderSettings::GetLinearFogEnd

    Case ID# 810208 is where I reported this issue.
