Well I had finally had some success last night.  When I set up the options and proceeded to render to disk , Vue would issue a popup about disabling some things, one of which was the Z-plane.  It warned me if I didn't disable memory consumption would slow the system down considerably.  Once I decided to say do not disable things started working. And yes I see G-Buffer but I did not need to choose to make it work. Seems depending on the preset quality it is only available to some like Ultra.
