@solarnoise: try disabling your sound card in device manager and then run the game and see if it plays the same. if the lag / stutters are gone, check out this thread for the fix: http://www.sevenforums.com/gaming/31980-lag-online-games-windows-7-a.html#post331641

Dont touch the registry, it wont fix anything for TF2.
That and the fact that by the sounds of it you are unfamiliar with the registry, I wouldnt go near it
