At a loss for how to fix lag/multicore

[slouth]

So I've tried everything I've seen on this site, Dumped Vista for win 7.. Nothing seems to fix the issue.

I can go anywhere from 5-20min before everything is so choppy, does not matter what zone, or what im doing. If I leave it alone for 5-10min it will come back. I'm starting to wonder if installing the Secerts of Fay version might help (not sure what mods would be requried to make it work with project 1999)

Amd Quadcore 9650
