Do we need a game forum or what? :)

For the pausing ( when another process is running ) what about just suspending the thread that does all the calculations instead of terminating it. This will drop its CPU use to 0.

Also lowering the priority of the other thread to 1 ( idle ) and having it sleep for 7 seconds or so between checks of active tasks.

I guess an alternative is to put a long sleep (60 seconds) in the calculation thread and have it repeat the sleep as long as needed. Some variable holding the state. if sleeping = 1 { sleep 60sec }

When the process that initiated the pause is no longer running resume the suspended thread and restore the priority of the other thread. ( I guess this part is obvious, just stating to be complete. )

I've had a problem like that after installing a servicepack on a dual P3. In task manager the performace tab only showed one cpu.

Turned out to be an option in task manager. View/CPU History/...
