Howdy 
Currently playing through Prototype, and I often get drops to ~25 fps where I have visible chug.
The funny thing is, whilst the game is using both cores of my 4870X2, both cores are only at ~40% load, so I've no idea why it's not using both cores to their potential in order to gain FPS.
Surely my Q6600 at 3.2 isn't bottlenecking the game?
Playing at 1920x1200, max settings, 4xAA.
