Manually adjusting this CVar is no longer needed as of 3.3.2 unless you're trying to run the game on specific cores. It is now uncapped so it will run on whatever core your OS deems as fit. If however, you want to specify which cores wow runs on, continue reading.

This cvar determines which cores of your processor wow will load & run on.

Changing this setting requires a restart of wow.

To make this change, you need to open your Config.wtf file, and then make the changes.


Customizing your settings for multi-core processors:

To customize which cores WoW uses place SET processAffinityMask "x" in your Config.wtf where x is the corresponding value in the following table.
