Direct X 10/11 Question - Answer (Translated)

[viion]

Tesselation actually can make the game run faster. The GPU has a seperate tesselation unit. They could reduce the default polygon count of all objects in the world and by applying tesselation near objects would still have more detail than they have now. You could even display more players at the same time.

I never knew that, quite interesting, im tempted to redownload Crysis 2 to see how it'll handle with Tess on.
