From What I can Understand with My Upgrade From a Intel Penitum D(Dual-Core) @ 2.80GHz Into The Intel Core2 Duo @ 2.80GHz.....Even With The Updated Video Card And RAM I Got FPSC Still Runs And Loads About 2-4 times Faster And Better Then Before....I've Tested It With My Old 2GB Ram and ATI Raedon HD 2600 XT and It Ran Almost The Same (Almost Being as It Was a big Map)...So I Guess It Does Suport Dual-Core Somewhat....Altho...I May Be Wrong...
