Skyrim does not make use of DirectX 11's Tesselation, Multi-threaded Rendering or DirectCompute. (From what I understand)
For all intents and purposes, It's a DirectX 9 game.
Bethesda said themselves they went out of their way to make sure the game looks and plays the same on all platforms and the PS3 and X360 are DX9 capped consoles.
Better Anti-Aliasing and Further Draw Distance are the only things you'll get on the PC version over the console versions.
But the lighting effects and textures are most likely the same as the consoles, just with support for higher resolutions on different monitor settings.
