Grid K2 & ESXI 5.5 & Server 2012 & ACAD Revit 2014/15

Passing the K2 card through ESXI 5.5
Server 2012 recognizes the K2 cards in device manager
I am able to install the correct K2 driver package in server 2012

However Revit 2014 and 2015 will not use the hardware acceleration of the card and goes into software emulation mode.

Any ideas?

Thanks
