CPU Multithreading please.

It is my understanding that process affinity was originally included in the config but has been removed quite a while ago with subsequent patches.

At some point I added the line back in with a value of 15 and performance was not only not better it was worse on my comp.

I do agree with the game benefitting from increased cpu performance/overclocking, I have the same experience here with a much better fps rate when I run the game with my cpu overclocked ( right now up to 4.1ghz ). At the same time game performance imo is as well influenced by how the ram is configured upon cpu overclocking.
My so far best playability I think I get when I have a mild overclock (3.8ghz) on the cpu just with the fsb while having the ram increased at the same time.
