Re: Attention: Dual Core Performance/\"Random Crash
I would like to add to this as I have spent the last several days unable to play many games (including Sin:E) with this exact problem. I had tried doing everthing mentioned in the above link with absolutely no success. After hours of work I finally sorted the problem, the answer was surprisingly simple.
If you have an ASUS A8R32-MVP Deluxe motherboard as well as a dual core processor, update your bios to solve the problem.
