i think this is the case w/ anycomputer on any game. if your machine is dirty then of course its gona run slower than somebody else. Thats proly the reason my computer runs so great on games because i dont have hardly anything on it.
The only way it'd run slower is if you had a bunch of crap running as well...you can have a machine filled with crap but not necessarily running anything....multiple installs and uninstalls and crap like that....it's not a matter of the game running smooth or not in some instances....it's the game simply not wanting to run at all, or basically nowhere near what it should
