This means that if a WDDM driver fails at most the affected application will quit unexpectedly.

XDDM/XPDM was eventually excluded from Windows 8/Server 2012 and above leaving WDDM as the only available option. I guess Microsoft wanted to correctly transition towards the new model. Even though WDDM was the new model, Windows Vista/Windows 7/Server 2008R2 OS could still make use of XDDM/XPDM. Since the Windows XP/Server 2000 days the XDDM/XPDM (Windows XP Driver Model) display driver model was used right up until Windows Vista/Windows 7/Server 2008R2 which saw a new model called WDDM (Windows Display Driver Model) introduced. Let’s talk about how Citrix evolved from having one mode to the now current five different types of graphics modes: If clients did not support the default H.264 codec that is used with setting Use video codec for compression, then a fallback to ThinWire+ (ThinWire compatibility mode) occurred. In previous versions of XenDesktop 7.x DCR was enabled by default for Desktop OS machines but is now disabled by default in the latest versions. In XenApp and XenDesktop 7.6 FP3+ Use video codec for compression was made the default setting for client devices that supported it.
Citrix XenApp and XenDesktop 7.x provide by default policy settings that will fit most graphical experience use cases without the need for additional configuration. ThinWire is always evolving to keep up with hardware, operating systems, networks and other components that make up XenApp/XenDesktop. This will help you make decisions going forward and re-evaluate decisions with new deployments. Note: When upgrading Sites, benchmark current performance metrics to get an idea of what experience users currently get. Upgrading Citrix deployments and not sure what to choose?.Do you want to improve the user experience?.Which HDX display mode should you be using? There’s no quick and easy answer as the real question is which mode will fit in to your infrastructure and business/user requirements.
