all of these things don't really add anything new, we had tessellation on GPGPU before, but it was all third party and more convoluted, so its more about ease of development than new stuff. if anything its probably better for developers production times than it is for the end user! no complex art pipelines or engines, automatic performance scaling (the card knows how fast it is and can dynamically allocate the right proportion of triangles to every object in order to reach an exact total frame poly budget). which is something that devs already do manually, and painfully in dx9 games. this is just a software thing too, so its not really hardware dependant (you don't need dx11 hardware to benefit) the other really useful feature added is tessellation. also, dx11 doesn't really add much, it just kinda improves on dx10 and adds a couple of really useful things that should actually make life easier for everyone (kinda like win7 compared to vista I suppose) it adds proper multi threading in the drivers and allows the rendering engines to be multi threaded now. as people flock to win7 with dx11 built in, that won't be such a big problem.

The biggest thing with DX10 was that it was vista only, no XP. We're not going to see much of a jump until DX9 is dropped completely, and especially with consoles running around DX9-ish, it's not going to happen till they upgrade, probably. I have seen some absolutely amazing things done with DirectX 10, but only because the engine was purely for DirectX 10, and to my knowledge, no one has even attempted that with DirectX 11 yet anyway.To reach the broader audience, games are coded with DirectX 9 in mind then have DX10/11 tacked on with a few features.

KelavarusThe thing is, same with DirectX 10, you aren't going to see considerable difference unless it's coded specifically for that API.
