Having written a little about VDI and RHSD the other day, I see that Register has an item about RemoteFX and playing games.  This uses the technology of RDS as well as either VDI or RSHD.

While you can play games, Windows 7 renders in all it’s glory too.  One word of warning from a licensing front.  If you are using RemoteFX then you will need an RDS CAL when you are buying the licenses as RemoteFX is licensed by the RDS CAL and remote admin tasks that you can do on a server without needing a RDS CAL does not include playing games (IMHO).  You also need to check that you have a client device that can handle RemoteFX. 

While platforms like Citrix, Quest and VMware will enable various remote access technologies that do not use RemoteFX (Citrix and Quest will even allow the use of their own technology or RemoteFX) the device chosen still requires the capabilities to display the high quality applications and games, even if not enough to process it all in the first place!

For example, for Citrix to use the GPU on the client to redirect Aero, it requires a Windows Client, even if it is not Windows 7.  Look at http://support.citrix.com/proddocs/topic/xendesktop-als/hd-aero-redirection.html for an example:

  • Hardware
    • Windows Aero capable DirectX 9-class GPU that supports:
      • Pixel Shader 2.0
      • 32 bits per pixel
      • 128MB memory
    • 2 GHz non-mobile central processing unit (CPU). Citrix recommends 3 GHz for optimal performance.

    Note: Dual monitor sessions are supported for user devices with a single GPU. A single GPU is defined as a single entry under Display adapters in Device Manager and not as the number of PCI cards plugged in the device. A single PCI card can have multiple GPUs on it.

  • Software
    • DirectX 9.0c runtime (Windows 7, Windows Vista, or Windows XP)

What this all means is that you still need a good graphics card somewhere – the desktop or the server and some reasonable network bandwidth if you want good graphics!
