I assume you've tested this and confirmed it to work on Windows?
I thought that I could assume that such hardware demanding game allows to use more than one core. I couldn't even think that it could be otherwise.
Although I haven't tested this myself on MS Windows but you can take comment #123 from bug #16328 as a proof.
