Citrix Thin. Wire HDX Graphics Modes what is right for you JGSpiers. Desktop Composition Redirecton DCR, Thin. Wire Legacy, Thin. Wire, Framehawk. Which HDX display mode should you be using Theres no quick answer as the real question is which mode will fit in to your infrastructure and businessuser requirements. Do you want to improve the user experience Stuck for bandwidth Increase user density on servers Upgrading farms and not sure what to chooseNote When upgrading farms, benchmark current performance metrics to get an idea of what experience users currently get. This will help you make decisions going forward. Thin. Wire is always evolving to keep up with hardware, operating systems, networks and other components that make up Xen. AppXen. Desktop. Citrix Xen. App and Xen. Desktop 7. In 7. 6 FP3 Usevideo codec for compression is now the default setting for client devices that support it. This applies to both Xen. App and Xen. Desktop. In previous versions of Xen. Desktop 7. x DCR was enabled by default for Desktop OS machines but is now disabled by default in the latest versions. If clients do not support the default H. Thin. Wire Thin. Wire compatibility mode is used. Lets talk about how Citrix evolved from having one mode to the now current five. Since the Windows XPServer 2. XDDMXPDM Windows XP Driver Model display driver model was used right up until Windows VistaWindows 7Server 2. R2 which saw a new model called WDDM Windows Display Driver Model introduced. Even though WDDM was the new model Windows VistaWindows 7Server 2. R2 OS could still make use of XDDMXPDM. I guess Microsoft wanted to correctly transition towards the new model. XDDMXPDM was eventually excluded from Windows 8Server 2. WDDM as the only available option. WDDM benefits WDDM partly runs in user mode. This means that if a WDDM driver fails at most the affected application will quit unexpectedly. Previously with XDDMXPDM the whole system would crash with a blue screen error as it ran within the kernel. Graphics command scheduling so more critical tasks can run in priority to improve user experience. Better performance and more reliable than previous models. Alows Windows to use features provided by Desktop Window Manager such as Aero effects like Aero Glass, Aero Peek, Aero Flip and more. Note Desktop Window Manager was introduced in Windows Vista. Prior to DWM using old display model each program was reponsible for updating its own window in the display mode. Now DWM is the one reponsible. WDDM version timeline WDDM 1. Windows Vista. WDDM 1. Windows 7. WDDM 1. Windows 8. WDDM 1. Windows 8. 1. WDDM 2. Windows 1. 0Specific enhancements introduced in each version are explained at https en. WindowsDisplayDriverModel. So with these changes to the driver stack within Windows, Citrix had to rewrite their graphics driver to be compatible with WDDM. The driver we are interested in is called CTXGFX. EXE. This user mode graphics driver works closely with WDDM and is responsible for encoding what you see with your eyes, on the screen, when connected to a VDA and passing that data to Receiver which runs on your client device, which is then decoded and displayed. Now what are the five HDX display modes I mentioned Desktop Composition Redirection DCR Deprecated in Xen. App and Xen. Desktop 7. H. 2. 64 Also known as Thin. Wire Advanced and Super. Codec, labelled as Deep. Compression. V2. Encoder within Director etc. Uses CPU on VDA and user device to encodedecode. The first version of this codec used the n. Vidia GPU with HDX 3. D Pro. The same codec that is used by many video sites to deliver high quality video across the internet which is compressed using H. Recommended to be used for server VDAs, WAN and mobile. Not really beneficial in a LAN environment as bandwidth is generally not an issue and enabling H. CPU consumption on the VDA. Video is mainly the biggest consumer of bandwidth so needs to be delivered efficiently which is why H. Provides a high definition user experience. Users on LANhigh WAN bandwidth connection to backend VDAs is advised. Minimum 2v. CPU4. GB RAM recommended on VDA. Heavy encoding means CPU is needed to compress the data to be sent over the wire. The encoding and decoding procedure results in extra CPU processing on VDA and end user device so keep this in mind as it will affect server scalability. Windows 7Server 2. R2 VDA or newer recommended. Will work so long as DCR and Framehawk are not enabled. Receiver 3. 4 for Windows, 1. Mac, 1. 3. 0 for Linux, 5. OS, 3. 4 for Android and HTML5 Store. Front 2. 1 required at a minimum. Note Receiver for Mac uses FFMPEG to decode H. Receiver for Mac 1. Video Toolbox Hardware Accelerated H. Video Toolbox H. 2. FFMPEG due to be removed in future versions. This mode is currently the default mode in Xen. AppXen. Desktop however in v. Sonic Before The Sequel Play. H. 2. 64 will be used when preferred by default meaning when it is unpreferred you will be using Thin. Wire. Personally, Ive not been able to get a scenario where H. If it was me, I would either change this setting to Use video codec when available if you want H. If policy Desktop Composition Redirection Disabled is set by default it is H. Also Framehawk needs to be disabled so that it does not take precedence over H. Xen. App Xen. Desktop 7. In 7. 9 the default was Use video codec when preferred which meant if using video codec compression wasnt preferred then Thin. Wire is used. Now in 7. Thin. Wire with selective H. When configuring the Use video codec for compression policy setting now in 7. Use when preferred The default, the system chooses when to use codec compression based on various factors. For the entire screen Use compression for the entire screen. For situations where heavy use of server rendered video and 3. D graphics are in use. Do not use video codec Simply disable video codec compression. This will degrade sessions that use multimedia content heavily. In an environement that does not often use multimedia you can select this option to disable the use of video codec compression. Doing so will increase server density. For actively changing regions Forces the dynamic use of compression for actively changing content on the screen and not for static or slowly changing content such as text or static images. This is a best of both worlds scenario as it helps maintain server scalability whilst compressing changing content to save on bandwidth and provide a good experience to users who need it. Receiver 4. 5 for Windows and Receiver 1. Linux is required for selective H. Older Receiver clients will fallback to Thin. Wire. Xen. Desktop 7. H. 2. 64 hardware encoding which offloads H. GPU for machines using supported NVIDIA GPU with HDX 3. D Pro. This is enabled by default. This frees up the CPU potentially increasing host scalability by 3. NVIDIA in a recent scalability test. This encoding is not supported on HDX 3. D Pro VDAs using selective H. Full screen H. 2. HDX 3. D Pro VMs when performing hardware encoding. The policy to control H. Use video codec for compression and the default setting is Use video codec when available in 7. FP3 and Use video codec when preferred in 7. If maximum user density is desired, Citrix recommend you disable Show window contents while dragging.
