Editing WoW:CVar processAffinityMask (section)

== Optimal settings for multi-core processors (pre-3.3.2) ==
Originally pre-2010, the general idea was to not only enable wow for all cores, but to also limit each physical core to one logical core, in an attempt to avoid letting WoW use HT or Hyper-Threading. Even though the original issues no longer exist post-3.3.2, the affinity mask itself is well documented, and still a hot topic in general inside and outside of WoW. Limiting the number of wow cores can still be a useful tool as a form of throttling WoW, or dealing with WoW specific performance/cooling, animation, or GPU issues, or for running VMs, or can even help in running multiple games at the same time.

Here are the original pre-2010 optimal settings for reference:
* Dual-cores (both of the 2 logical):
    SET processAffinityMask "3"
* Tri-cores & i5s (all 3 logical):
    SET processAffinityMask "7"
* Quad-cores no HT (all 4 logical):
    SET processAffinityMask "15"
* I7s with HT enabled (primary logical of every physical core, 4 total, bits 01010101):
    SET processAffinityMask "85"
* 16-core/8-core hyper-threaded (primary logical of every physical core, 8 total, bits 0101010101010101):
    SET processAffinityMask "21845"
