Long shot here but did anyone ever figure out how to stop the stuttering in this game? I recently purchased it and having the 30fps issue as well, even if I disable Vsync the game will run 200-300fps (according to FRAPS) but frequently drops to 30fps out of nowhere which causes the unwelcome stuttering. Other Lego games such as the recent Lego Batman 2 DC don't have this issue. Edit: Forcing triple buffering with D3DOverrider seems to be the best bet, it reduces the symptoms at least. I got it from here.
