Why does a human brain consume so much less energy than something like a gaming PC? How is the human brain so much more efficient? Or am I asking the wrong question here? Pic unrelated

You could imagine playing Crysis in your head with decent accuracy, so in a sense yes

Maybe not but I can imagine things in almost perfect resolution and operate in physical space better than most robots for less energy. Will qualify the robot statement by admitting that a robot arm can always assemble a panel faster than me, for longer too.

Nuh uh. I don't believe you can imagine accurate soft shadows for a complex model in real time.

No, but I can imagine what they look like. I'm just skipping the calculations and imaging the shadows just being there. Is that the difference? And if so, how is the brain able to just come to a conclusion without any calculation being done?

Does this mean it's just calling up precomputed libraries to solve?

You've never imagined a ball of light going around a post and the shadow moving? You've never dreamed a sunset and saw shadows playing across the landscape?
