I'm glad this has helped other people but to be honest I expected maybe one other person to have had this issue. I really think this is an isolated issue and a very specialized fix. I would like to hear feedback from more people on this. I expect more performance decreases than fixes but it doesn't hurt to get as much data as we can. After working with this for a while I believe it is related to GTX 2xx series cards under Windows Vista. :thumbsup:
