The systems they are currently using are probably Running Vista/Windows 7. Right off the bat, those two OS's use a heck of a lot of RAM. When you have a game like SOW that requires a lot of RAM, especially for larger maps you have the OS and the Game fighting over who gets the most RAM. Hence the stuttering. Another GB or two would have probably let it run smooth as glass.

The reason they didn't have that option was the people setting up the show made them use their PC's and for some reason they didn't put nearly enough RAM in them to showcase newer game like SOW. Your average FPS or MMORPG probably isn't going to need that much RAM, but a game like SOW will, and they should have known that and made some provisions.
