Flanker with Processor affinity you can set everyone to run one one core and the game on the other. This is a breakthrough in gaming as the other core handles all background and the other "gaming core" is not burdened. The origanal Xbox can produce some pretty impressive games for being a Pentium 3 and using a card that is not as good as a 6800GS even but it doesn't have background services to run like an OS, music, firewall, webserver, or any of that. The same is applied when you use processor affinity an unburdened system can do alot with little to work with.
