Everyone seems to have their own opinion regarding what makes Supreme Commander work best and unlike many games available today, Supreme Commander is dependent on just about everything. The more processing power you throw at this system the better, though I do not agree that multi-core processors ensure excellent performance. I ran a few tests using Core 2 Quad and Duo processors and noticed that the second, third or fourth cores did very little when compared to the first. In the most intense battles the first core would operate at around 90 ~ 100% where as additional cores worked between 20 ~ 50%. Of course this helps, but evidently Supreme Commander is not designed to fully utilize multi-core processors, or at least we have not seen it do so.
