Answer 1

Games, almost all, are written, and developed, to run on the LCD (lowest common demoninator) of hardware, to sell to the widest audience possible.

Why spend money developing for multi-processor/multi-core/multi-thread machines?

And what ‘Other Tasks’? For a single player game, the tasks are probably 95% rendering, 5% actual logic. For MMORPG’s, 85% rendoring, 10% dealing with comms, and 5% actual logic.
