Quad-core Processing?
CoH can utilize two cores. It cannot utilize all four (or more if you have more).
However, that does mean you have two (or more) cores that can be used for other programs' needs (like Photoshop, etc.)

The setting you are referring to is obsolete. The -renderthread command that enables use of another core has been enabled by default for some time now.
On a side note, CoH can use 4 cores, but only if you have 2 clients open and running at the same time. haha */joke*
Somewhere in this mess, a while back i stumbled on a thread that talked about setting the client to use both processors on a dual-core to increase framerate. I have since forgotten how, and cannot find it anywhere. My question mainly is, is there a way to tell it to use all 4 on a quad-core? If so, how do I do this?
