Unigine Heaven Update Coming With OpenGL Tessellation

[Nille]

This seems like a good time to remind that the OpenGL/OpenCL stack in the Linux Catalyst driver (aka fglrx) is the *same* as the one in the Windows Catalyst driver.

No one say that OpenGL is better under Windowns And under Windows the most Apps use D3D.

I believe jrch2k8 was - the post I was responding to seemed to imply a big difference in quality between a feature in fglrx and the same feature (OpenGL 4 in this case) on Windows :

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.

Are you saying the post was really about DX11 vs OpenGL rather than the Windows and fglrx implementations of OpenGL ?

well, has someone tried unigine on windows with opengl on ati?
If yes, and it works, we know that unigine is bullshitting around.

It worked fine last time I tried, which was with Catalyst 10.3 I believe.

well ok unigine demos for now are only eyecandy i give you that, but remember some games from that engine are coming for linux too, so eventually would be peachy to have full support for that engine.

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

I have to ask you this. Do you own an ATI card? Or are you just a nvidia fand bashing ATI?

well, then we have it:

unigine is talking bullshit. Who is surprised?

Not unigine - I've never actually seen any official word from them. Well I'll correct that; someone did ask (I'll have to dig back a while to find a link) and unigine replied that it was not amd's drivers holding things up.

Here we go, post #18:

and how does that fit with the phoronix stories?

[mirv]

A lot of information comes from phoronix - but very few actual links to sources of information. Sometimes it's an opinion of phoronix, not actual current information. So until I read a direct quote from unigine, I will take any phoronix story with a grain of salt (just like semiaccurate articles).
