This took me a whole day to make, damn.

So yeah. I'll be downloading this the day it releases now. To be honest, I was a bit wary because of the very vanilla looking way of the textures (in terms of style), but that pic right there is enough to convince me.
would it actually be possible to implement dx11 features like tesselation in skyrim, once the creation kit is released?
Contrary to what Todd Howard said (shocking, I know), the game does not utilize DX11 in any shape or form. There are libraries for DX10, but even they are not utilized to my knowledge, as the game is full DX9.
Maybe SKGE (it it exists at some point) might be able to do to Skyrim what MGE did to Morrowind (basically change it from a DX8 game to a sort of DX9 game), but even then you'd have to consider the nightmare of creating tessellation maps for each texture that almost every texture modder (who would wish there textures to be compatible) would have to do. And as far as I know, creating a tessellation map is more complicated than creating a standard normal map.
