how can i enable GPU pass-through on hyper or it haven't support it?

Hi guys,

I  have just installed  Hyper-v 2012 R2 and trying to enable GPU pass-through support for VM.

And I noticed that there is a RemoteFX GPU on the hyper-v server setting page.

RemoteFX GPU is not same as GPU pass-through(directly pass the whole GPU to vm), am i right?

thanks for your help
