RemoteFX, HyperV and RDP with Windows 2012 R2 client side

We have a deployment scenario of:

Dell VRTX, with hyper-visor being Hyper-V 2012 R2.   This will have VM's which are Win2012R2 Terminal Services (session based and therefore meaning that session is Win2012R2 being clientside (like in this thread).  

Can we take advantage of using RemoteFX (PCIe GPU's) to increase the capability of the 2012R2 terminal services session client in what i consider as GPU passthrough ?   Note this is not using Win8Ent as a VDI in RDP.

We are just finalizing specification for our purchase of the VRTX and the correct hyper-visor method and prefer to stay with MS, but on reviewing threads and MS blogs such as this we are not sure this is possible.  

Thanks in advance.
