People posted screenshots at neogaf that showed texture blurryness/distortion with tessellation. Looks like we're in for a new set of artifacts with this tech to add to our blocky shadows and shader aliasing.

It is becouse the surfaces originally are flat. So when this techdemo that exaggerates the 3D bumping the textures get distorted along the edges (stretching). Though it would still get with less bumping. Should not be very visible and it is and was already present in games that use parallax mapping and parallax occlusion mapping. So I dont get the worries. I didn't hear anyone complain about this in Crysis for example...
Q9550 stock, ATI 5850 stock
1920X1080 2XAA DX10 no Tesselation 41 fps
1920X1080 2XAA DX11 no Tesselation 42 fps
1920X1080 2XAA DX11 + Tesselation 26 fps
I'll take Parallax Mapping anyday, it was one of the aspects of CE2 I thought was the most visually impressive. Though of course this next step, Tessellation, is a much bigger improvement still. Obviously it was very exaggerated in this demo in parts where it shouldn't be (boulder path). Would Parallax be better used in those circumstances where you don't need such extensive differences? Better performance?
IMO, no. Not even close after having seen both in action. There's places in the demo you can see much less exaggerated use of tessellation, and it's still quite impressive.

And there's quite simple reasons for it too; DX10 required complete rewrite of "everything", it wasn't compatible in any way with DX9 so there was a lot of work to be done.It looks like DX11 is being pushed much faster (and more successfully) in game development than DX10 was, so perhaps there is hope. I may be buying a card sooner than I think.
DX11, tesselation, 4xAA, 8xAniso: 15.8 fps, score 399
DX10, (obviously no tesselation), no AA, 4xAniso: 33.2 fps, score 837
IMO, no. Not even close after having seen both in action. There's places in the demo you can see much less exaggerated use of tessellation, and it's still quite impressive.
