    Why are there such major bugs in the driver, that an techdemo can't run and will therefore not be released? Why doesn't the target audience of FGLRX (which is not Joe Sixpack, but professional CAD) complain? Or are all those using QuadroFX cards?

    Btw: Tweo days ago I ran the Tropics and Sanctuary demo in fullscreen and windowed mode with compiz enabled under catalyst 9.10 and did not have any problems

      The problems are with the new DX11 features that AMD is creating OpenGL extensions for, not anything that current applications use.

        Thank you for clarification!

          Actually, the FireGL crowd is the very reason we HAVE the drivers in the first place. It's just happy happenstance they do good all over anyhow.

          Having said this, much of the CAD space doesn't even remotely USE the same driver paths as the game-centric type rendering uses. Most CAD programs use immediate mode rendering calls, most modern game engines (but not all...) use vertex-arrray/VBO and shader based rendering. While most modern cards use shaders all the way through, the basics are only really ever used with a CAD program and may not see the same issues something like Unigine will present with a given driver. They're not testing against it as much because AMD still is worrying about their CAD customers that they're providing the drivers for and not so much gaming, etc.- because we're not perceived to be that market segment to them in the large right at the moment. Sort of a chicken and the egg problem- one I hope Gallium3D will come along quick enough to make the problem less of an issue and show there IS a market for them and they need to worry more about the top-end performance while helping the community maintain about 70% or so of the peak as an out of box experience to goad their sales on upward.

            Which wouldn't surprise me. Fortunately, the code-core is identical except for the edges where it ties into Linux, so it will be little time once the issues are sorted out on that end.

              Ratchet and Clank FTW! Oh wait...not on Linux.

                Tesselation info

                Lets get a few tesselation things the way the facts are.
                I've saw quite a few posts that are just plain ignorance regarding tesselation.

                At the moment there is no tesselation for opengl, not even in extensions, that works exactly like the DX11 one.

                However, ATI has had a tesselation extension in his cards for quite a few releases now. They will probably (that's just my guess) update it or provide a new one.

                Nvidia on the other hand is doing something strange. I haven't read it anywhere else except here: http://www.opengl.org/discussion_boa...rue#Post264535 which does seem to indicate that nvidia is indeed making a tesselation shader for OpenGL GL_NV_tessellation_shader. Which "seems" to be present in the 191.00 driver once released (pure 100% speculation on the pointed opengl topic) The person that made the post doesn't seem to making it all up

                So, if this is all true then it's just time to wait till there comes a OpenGL version that requires tesselation to be one of the core modules. (OpenGL 3.3? 3.4? 4.0?) They better be fast otherwise DirectX is indeed (since version 11) better then OpenGL.

                hmm.. i wanted to note down facts and i noted down a lot of speculation.. o well see what you do with it. it's interesting info and i can't wait till the 191.00 nvidia driver comes

                  I believe the ARB is working on approving a proposed unified spec for that...they had a similar spec approved out shortly after DX10 shipped that covered the functionality provided with that version of DirectX.

                  As it stands, it's somewhat debatable that having tesselation like we see on D3Dv11 makes it "better" than OpenGL. I'm fairly sure you can get at something similar doing CUDA or OpenCL as all of this is really little more than stream processing these days- it just won't be as clean as the other way.

                    Any way, looks pretty Unigine, some nice 3D artists you have there.

                    Oddly enough, I though about a Myst style puzzler.

                      Man, I love Ratchet and Clank. R&C runs on a PS3. Linux runs on a PS3. So close. So very close...
