A wrote a blog a while ago (read it here) about how although the Citrix Studio Console interface shows every policy for every graphics mode, most modern graphics modes need very little configuration and are affected by a few policies only. The majority of policies are actually associated with the Legacy Graphics mode (designed for use with Legacy OSs such as win7 and 2018 R2 and earlier), so in the future on modern OSs there is far little to configure.
Long term, it would be ideal if the Studio interface was redesigned to make this more transparent, I think it was assumed that because each policy is self-documenting users would read the legacy ones and realise they were not applicable, I’m not convinced this is the case. Many of the policies “sound” useful.
A few weeks ago I read a blog by a Dutch user trying out the new “Thinwire Compatibility” mode (read about it here), since writing about this I noticed that many of the policies he set were inapplicable to that mode. It’s very common to see this is customer deployments, admins fiddle and if they see no ill-effects often leave policies, or policies from old deployments get transferred to new deployments without review.
Use Templates to make it simple
To make it simple, XenDesktop / XenApp 7.3 FP3 introduced templates which provide collections of policies administrators can load to obtain a deployment tuned for various use cases, we would always advise users consider using a template before fiddling with individual policies. You can find out more about templates, here: https://www.citrix.com/blogs/2015/10/28/simplify-hdx-policy-administration-to-amplify-the-user-experience/
New whitepaper – which policies apply to which graphics mode
A new article, CTX202687 – HDX Graphics Modes – Which Policies Apply to DCR/Thinwire/H.264 – An Overview for XenDesktop/XenApp 7.6 FP3, has just been published which covers which policies apply to which graphics modes as well as the precedence hierarchy and receiver dependencies for those graphics modes. If you read this paper you’ll realise that most modes have 5 or less tuneable parameters (some have just 2!).
Please read the CTX if you are unsure on which policies to set!
