Q: What are the requirements to use RemoteFX in Windows Server 2012?

DirectX 11 capable graphics card

Windows 8 64-bit WDDM v 1.20 driver (if you try to use a non-Windows 8 specific graphics driver, the graphics in the virtual machines--VMs--won't render correctly and tearing will be present, which the screen shot below shows). Using a Windows 8 graphics driver fixes the issue. 

SLAT-capable processor. Remember, a great way to check whether your processor supports SLAT is to use the CoreInfo utility from SysInternals.com (use the -v switch and a * should be shown next to EPT):

Remote Desktop Virtualization Host role service must be installed (to enable RemoteFX).

Enable the GPU for RemoteFX (see screen shot below).


VMs can now be RemoteFX-enabled by adding the RemoteFX 3D Video Adapter hardware to a VM and setting the number of displays and resolution (see screen shot below).
