That and the other problem im having is how laggy the game gets when 1-2 NPC's are on the screen, using the toggleemotions command in the consol tho really helps with that and i only starts to lagg when i have like 15 npc's on the screen now.. I also get the occasional jerking in the game where the fps goes from 60 and spikes down and then go back up.
Im on Windows 7 64bit, i havent tried it on windows xp or Vista, and i dont care too. I just want to play the game, and asside from the bugging out music i just ignore the jerks and the toggleemotions fixes the npc lag
