When using XenDesktop 7.6 on Windows Server 2008R2 with Citrix Receiver 13.0.4, 13.1.4 or 13.2.1 with H.264 Deep Compression Codec, dragged Windows lag and the performance is generally poor.


Server and/or client do not have enough computing power for the H.264 Deep Compression Codec.


Enable the legacy graphics mode on the XenDesktop 7.6 server via a policy.
