Yeah, saw your post a couple of minutes before, I haven't tried the shadows yet but I will, although I dont think that it would make much of a difference to the 5fps :( About the hyperthreading, that's a whole other story and I have had nasty experiences in the past fiddling with it. For the rest of your twicks, I have allready changed everything from high to ultra-low in a desperate attempt, and I experienced no change with fps. Pretty much means the flow is within the code.
