Well I think that maybe that could play an important part for the realistic simulation, but notice the huge detail on the characters for a second:


The game FarCray 2 require a powerful computer to be played in high level of details, but still really tricky to me how they make it.
All the opinions are acceptable. I'm just looking for and answer that light my ideas of how to create something with the high visual detail as that game.

Thank you in advanced.
