FPS solution that's worked for me.

[PotNoodles]

I was getting really quite frustrated with this game because I have a good specs computer, but tonight with the help of some good Samaritans on here, I have finally fixed my FPS issues. The solution for me was to turn off Hyper-threading in the Bios and I disabled turbo boost. I also run Gamebooster that stop background programs you don't want running. Before I did this I was getting bad stuttering and my frames were a constant 30 - 60 FPS up and down. Now with the new setting I get 55 -60 FPS most of the time and far less stuttering. My system spec is listed below, I hope this helps someone else because I'm pleased that some people helped me out with this.

Quadcore i7 930, overclocked 4.0ghz
