HDX 3D Pro Performance Video is Poor

Written by Thomas Poppelgaard on. Posted in Citrix, HDX 3D Pro

Citrix have posted this knowledge article regarding Citrix XenDesktop 5.x HDX 3D Pro i want to share with you.


HDX 3D Pro Performance Video is poor:

  • Image quality choppy, additional lines appear when moving mouse
  • Interaction with machine is slow and unstable when running heavy
  • Blurriness of the screen


The cause is because the HDX key file in the user profile was unable to load.
The key file has to be present in the application data of all users who want to use the HDX 3D Pro.


You can resolve this issue by installing or reinstalling Virtual Desktop Agent 5.5.100 and update to receiver 3.2.
: You can also install the Virtual Desktop Agent for HDX 3D Pro from a command prompt.

To install HDX 3D Pro, run XenDesktopVdaSetup.exe and include the following arguments in addition to any others you might need to use:

/KEY_FILE <path>, where <path> specifies the location of the HDX 3D Pro key file
On host computers running Windows 7, include /INSTALLONWDDM=1

Hey Thomas,

nice article! I was wondering if you have a link to an official statement of Google (Chrome) about this change. I’m having the opposite experience with V45. Each time I start it, Hardware accelaration is used, except for Canvas, Multiple Raster Threads & Rasterization. I’m using it on a non GPU accelerated XenApp 6.5 farm on 2008 R2 OS.

Thanks in advance



CCU for Maxwell (M6/M60) not for Kepler (K1/K2)
+ SUMS = % Sotfware maintenance per year related CCU licenses

Pricing structure will reach new heights………..

I was surprised and confused by what NVIDIA now appears to be stating about needing NVIDIA CCU licenses to use GRID 2.0 M6/M60 instances. Seealso http://www.nvidia.com/object/nvidia-grid-buy.html which implies that this licensing is needed above and beyond what licenses are needed from Citrix or VMware to access various features. Can someone perhaps provide better clarification? As far as I can tell, the GRID K1 and K2 units are exempt from this, so it would appear this is something new and specific to the M6/M60 models. If this is really true, the pricing structure could be a major factor in the decision to go with these newer models vs. the K1/K2 options.
