I have noticed that at some points during the game things stutter - as far as i can tell its is when the DVD is being accessed. My other theory was that it was GFX related but with all settings turned down low my 8800GT should be able to handle it i reckon. So... i tried making an image from the DVD and mounting it using Daemon Tools as i have done for other games i buy to stop me having to find the CD/DVD all the time. However Bioshock doesnt seem to like this and is telling me to insert the original. My question is - is there a way around this? Thanks Cyp.
