Well I think overall the tesselation is Crysis 2 was good, but it boggles the mind that like the Unigine demo, they heavily overtesselate surfaces that don't need tesselation (doors with flat panels for instance). I hesistate to think that they collaberated with Nvidia to do that in order to deliberately handicap AMD GPUs for absolutely no reason, but it's hard to keep that thought from popping up.
It's a shame that Crytek didn't wait until the Dx11 path was ready before releasing it. Because that combined with the high res texture pack makes for a radically different looking game than vanilla Crysis 2.
