The extra settings on D3D's render panel is a recent update release by D3D himself.  It can be found here:

Just follow the installation instructions. 

The difference between the Kids4 and Ben renders is due primarily due to the skin textures and shaders used for the default models.  As Laurie mentioned, VSS will correct that as I demonstrated in my renders.
