SC2 is strictly a 2 core software. If you set affinity to more than 2 cores, it will not run on the extra cores other than the 2 main ones. Most of the time, programs like to run on certain cores which in your case would be the third core. When I run SC2 on mine, it perfectly uses 2 cores. Core 0 and 1. I would probably set affinity to cores 0 and 1 if you don't have HT enabled. If you do, it will be 0 and 2.
