If the engine is thinking, it is hitting the CPU hard and probably hitting memory pretty hard. Most engines you can set so they don't think if it's not their turn to move. This is not really how they are meant to be used, so I'd do single-computer tests with caution. It's also possible that some programs can use CPU even when idling, so if you have a performance monitor you might wish to check that. bruce
