Thin Client without a virtualized Windows, Is that possible?

Is it possible to have all contents rendered in a Windows 8.1-Pro + NVidia Card based PC?

Is RemoteFX the only way to have that including GPU acceleration?

Is Mandatory to have virtualization?

I want to have a thin client connected to a host that renders all the contents. The client just have to "paint". All that I have read refers to use a virtual GPU and can't see why is no possible to use the real GPU if just one user is going to be connected remotely to the windows machine.

Thanks in advance
