One interesting thing about brains is that they are rarely found by themselves foraging in the wild. Usually they are attached to things. In fact, they are involved in many feedback loops involving sensory input and various effectors. As well as being directly attached to peripheral nervous systems and encased in massive bodies with various physical constraints, circulating hormones, social contexts...
It is hard to imagine raising a baby brain to chess-playing maturity without tons of informational input acquired by interaction with the world. (Even just keeping normal children in the basement is a profound intervention, and they still actually experience quite a bit). So I suppose you will have to speed up your realistic world simulation as well.
The brain is not a personal computer and its development is not a matter of factory production because it is not a piece of technology designed by people.
