Want to increase you're in-game FPS?

I also am curious why you think disabling the page file would help performance. If you are actually using the page file, meaning you are swapping, and you disable it, things are going to start crashing, no? I think a better solution is to have the swap file and the wow directory (or any other disk intensive application directory, actually) on separate disks.

This. Like Bob said, if you're paging, you need the page file or worse things happen to your computer. If you're having trouble with framerates due to paging, upgrade your RAM.
