RemoteFX is a Server only feature (2008R2 and newer). Windows 8.x lacks the host ability.
It also requires a specific GPU.

Desktop class cards may or may not work depending on market segmentation implemented by the vendor.
AFAIK, Hyper-V does not use VT-D. Hyper-V has its own methods to provide direct access to certain hardware. Namely: SR-IOV, RemoteFX, and direct disk passthrough. The first two items are not available to Windows 8.x hosts.

SR-IOV networking requires:
--A host system which supports SR-IOV (for example, Intel VT-d), including chipset support for interrupt and DMA remapping, and proper firmware support to enable and describe the platform’s SR-IOV capabilities to the operating system.
--An SR-IOV–capable network adapter and driver in both the management operating system (which runs the Hyper-V role) and each virtual machine where a virtual function is assigned.
Support for SR-IOV networking devices – Single Root I/O Virtualization (SR-IOV) is a standard introduced by the PCI-SIG. SR-IOV works in conjunction with system chipset support for virtualization technologies. This provides remapping of interrupts and DMA and allows SR-IOV capable devices to be assigned directly to a virtual machine. Hyper-V in Windows Server 2012 enables support for SR-IOV–capable network devices and allows an SR-IOV virtual function of a physical network adapter to be assigned directly to a virtual machine. This increases network throughput and reduces network latency, while also reducing the host CPU overhead required for processing network traffic.

I've written a few articles on how to get RemoteFX going (on 2012 in my case); in this guide I use a consumer NV 650 and it works great. I now use the RemoteFX VM as my main work machine either local or remote (over an RD Gateway). Kougar note you can setup a Gen1 or Gen2 machine with the newest Hyper-V, so that shouldn't be that big a deal. HyperV does use VT-D as well as a couple other techs.

Well now you can modify the size of the virtual hard drive while the Gen2 VM is running, and then extend the partition size inside of the VM, again, while it's running. Gen2 VMs also boot UEFI.
