XXHighEnd

A Core Appointment Scheme (4 being available) denotes how the multi core processor devides the tasks in the Operating System, with XXHighEnd and its applicable Audio Engine as the spider in the web.
No real rule exists and thefeore it is not important to know which scheme does what exactly; for this SQ parameter it is known that people undoubtedly perceive the difference in SQ at varying it, but that no best setting came from this (so far). It thus depends per PC what the best setting is.

There's also no rule to be found (again, so far) that any other setting depicts a certain Scheme.
Lastly it can be seen that once someone has chosen "his" setting, it is hard to step away from it. And otherwise it will be very rare (this is just statistics).

While the Schemes have been developed for sheer SQ reasons, in the mean time they (kind of obviously) also help in glitchless playback. Thus, when no glitchless playback can be achieved easily, chosing another Core Appointment Scheme sure may help (also for the worse).
It is also oto be noted that "how" it helps in glitchless playback is related to the OS used. There is logic in this because it is exactly this (how processor cores deal with various OS tasks) what changes per OS version and sub version (Service Packs). As an example of this counts that ijn Vista the Schemes were not necessary at all (to help glitchless playback) while in Windows 7 (no Service Pack) about all had to be changed (in XXHighEnd) to the Schemes could help out, in W7 SP1 all is fairly back to normal but still very different than in Vista.

All 'n all, no rules, but sure relevant to SQ.
Also : the better the PC is up to the tasks, the more the Schemes can be used for what they were intended for : SQ (because then all Schemes produce glitchless playback to begin with).

New for version 1.186 and beyond :

5 Core Appointment Schemes exist now, and each of them is extensively described in the ToolTip concerned;
The previously mentioned "no rules" is obsolete now and as of now rules sure exist.

Notice that the Schemes explicitly support 1, 2, 3, 4, 6, 8, 12, 16 and 20 cores and that each number of available cores is dealt with differently; the ToolTip explains is all.

For the Demo Version of XXHighEnd only one Scheme is available, with the notice that this is just the Scheme which has been used to develop the whole revamped setup of the Schemes, hence it should be a (or the) better one. It's just that Demo users cannot vary Schemes and find out the better SQ settings for that matter (which better SQ is always to be found by all of you out there, as you will know).
