That's not how it works, because...

World of Warcraft is going to launch off of the monitor that it's being told to launch from in its settings. If you open the game, and drag it from one monitor to the other it does not start rendering off of the second GPU, and it will, from what I understand, begin to render via software while still producing some sort of load on both GPUs. This is not ideal, and unless HKN has some built-in support to intelligently choose which display adapter to launch from, then what I just described is most likely what's happening.

If whatever you changed in your setup is working for you, then that's good, but you should really be monitoring your hardware at a time like this.
