funny how unigine blows the nvidia horn. Fermi sucks at everything but tesselation - so they release 2.0 which increases the tesselation load. And now this. Smells fishy.
"Smells fishy. " yes but Death fish.. because nvidia is a Death fish ;-)

i don't care about a benchmark or demo like unigin!
i care about real apps like "wine" !
and wine don't support dx11/OpenGL4 right now!
I'm not demanding it or anything, just curious, how hard would it be to get this into the radeon driver? Sounds tricky.
Err? Direct2D is only available under Vista SP2 and Windows7 and there is no foss driver for those. Under Windows AMD drivers have/had? only problems with GDI accel. not with Direct2D accel.

Maybe not promise but more advertise. AMD/ATI say we support OpenGL but now we have an Company that say the OPenGL Implementation from AMD/ATI is buggy and not usable ( There are some more companies that say that ).

yeah, well remember catalyst receive 99% of the love from amd, fglrx on the other side is heavily bugged to begin with, and 1 thing have fglrx proved in all this years, if it works at least decently on windows already on fglrx will take a hell of releases to even get close. so if direct2d follow the same path that 2d accel, xvba, stream/opencl, wine, etc have follow, well the first releases woud be havoc if you activate "direct2d" until several releases later

well wine working fine with fglrx is not going to happen any time soon, even the foss drivers are more compliant now than fglrx(ok slower, but the stuff render as it should or at least load the apps without sigsegv's, r700 still miss gl 2.1 support for now)
well remember opengl4 is not a different library or something else, opengl unlike directx doesnt need to have different library or api every version. aka
opengl4 use a lot if not most of opengl 3.3 and opengl2.1 and opengl 2.0 and ok you get the point.
so opengl4 is only a subset of additional functions that call a certain number of registries supported only in a specific set of hardware, in fact you can run tessalation on a non evergreen hardware for example having an opencl fallback (ok wouldnt be that cool as the supported hardware but it can improve the image quality in previous generation if you wanna bother in doing it). so even if you claim wine doesnt support opengl4(wich is only a limited set of function inside the gl library btw) , wine support gl3.3, so ok you miss the goodies of evergreen and some new shaders functions in glsl, but you are using most the gl implementation in fglrx wich is proved again and again to be buggy not only in wine.
so even if you had wine+gl4 support today probably all your games would be equally bugged as they are today
dunno i would just prefered that fglrx team forget for a time gl4 and focus on debug the most of their current libgl implementation, so they can later focus on get a superb gl4 now with a working 3d system, but well
