Steam VR Support - Parallels display adapter (wddm) Issues

I recently upgraded to Parallels 13.2 because of news that it supported Steam VR. I have a new MacBook pro and an HTC Vive.

After I upgraded and optimized the settings I ran the Vive VR test. Everything checks out except the "Parallels display adapter (wddm)".

Does anyone know how to fix this issue so that I can run Steam VR on my Mac? Is there a way to change or upgrade the display adaptor?

Any advice would be greatly appreciated.

Thanks,
Leif
