Editing WoW:CVar timingMethod (section)

== Details ==

When the game starts up without this variable or if timingMethod is set to 0, it checks to see if your processor cores can all work at the same speed. If it passes, it gets a 2. If it fails, it gets a 1. It's best to not edit this cvar due to the following:

If you force the game to use 1 but you have a multicore system and the cores sync up, you'll be using a lower resolution timer of around 64 times a second. The game won't run as well if you're capable of more.

If you force the game to use 2 but your multicore system do not have cores that can sync up, you will experience significant timing issues like your cooldown timers and the actual spell cooldown being way off, or spell/projectile speed issues.
