Tessellation is really nothing but glorified LOD, also there is no way you could even tell that from the video, that has to do with preformance, not necessarily graphics
Dude! the difference between hardware tessellation and not, is poly count on screen can potentially be
orders of magnitudes greater and rendered on the GFX card and cheaply for what it is. It's like the difference of N64 poly count and oblivion poly counts. LOD is a huge bonus. You make it sound like tessellation isn't THE [censored] or something. Once you have run a tech demo of it I don't know how you can go back to seeing polygonal silhouette ever again or cheap parallax shaders as a total substitute
While I am all for discussing skyrims graphics, and being honest about the level of detail it actually has, shaders, polycounts, texture resolutions, + modern graphics features and all that jazz, I don't think holding a picture of Crysis up is very smart, it's just not realistic to think that can ever be the case. It just makes me groan when I see an image of a crysis head in all it's glory in its fancy over the top renderer, and even for a second get your hopes up.
