Now, I'm not sure if it takes advantage of Dual Cores or not. I had to run in and edit files in regards to the engine and basically rework the inner codes of the game.
Several sites that I've been investigating this on claim that it does accept Dual Cores, others that it doesn't (so all that time I spent may have been for nothing).
I'll look more into this and also check to see if I've preformed "illegal activities"...
