I'm claiming that at this level hardware power, the hardware power isn't the limiting factor in realism, the animations are.
Realistic visuals needs realistic walk cycle. But since realistic walking isn't a perfect stable cycle (it is disturbed by head/hand motions, surface variations, etc), there can be no realistic walk cycle because real walking isn't a cycle. AFAIK current videogame animation all involves walk cycles. Realism at this level of detail needs some new form of animation, not the love and care of a person that is so present in this demo.
