In addition, different game threads for the same game (or even functions within the game threads!) may benefit differently. Physics calculations may benefit from cache in a different way from other game calculations. Even if you zoom into the different type of physics calculations, there are ballistics, soft-body physics, hair, clothing, foliage, water, etc. It would be interesting to see what kind of performance could be achieved with PERFECT scheduling. That would probably require the CPU to do process scheduling via specialized circuitry though as opposed to (or in conjunction with) the OS.
