(Get the code!)
I noticed an odd but possibly related behaviour:
1. I had set up_threshold to 40 instead of 95, and everything was running fine even after hours of running the kernel.
2. I changed it back to 95, and the frame rate slowed.
3. I tried changing ignore_nice_levels to 1, but it had no effect on frame rate.
4. I tried changing up_threshold back to 40 and then changing the CPUs to performance instead of on-demand, but neither had an effect on frame rate.
5. I ran glxgears. This normally gets 3500 fps, but could only manage 1.5 fps this time. However, in the wine CoD4 app, the frame rate increased back to normal while glxgears was running. Stopping glxgears made it drop again.
