I'm changing this to compiz as I no longer think it's a scheduling issue - setting the up_threshold to 40 masked the problem, but as soon as I changed it back to 95, the problem reappeared.
When I reproduce the problem, turning off compiz restores performance to CoD4 - normally it makes no difference whether compiz is running or not. The last time I reproduced the problem, I turned off compiz then turned it back on again while CoD4 was running. On quitting CoD4, the screen refresh became awful - I could actually see the screen being redrawn pixel line by pixel line. Switching to a console (ctrl-alt-f1) and back fixed it.
