Meh. Most people don't really care what something looks like in wireframe...
"Look at how many more triangles and wires and whatever you want to call them" Pfft.
But sure, the DX11 example did look better than the DX10 example.
As one person on that video commented:
i bet you can do this on dx10 they just dont want to do it
- I think that's true, to a certain degree.
