    Phoronix: Unigine Engine Advances, But No Linux Heaven Yet

    We reported a month ago that Unigine Heaven on Linux is still trash with the ATI driver so Unigine Corp is continuing to hold off on releasing the Unigine Heaven tech demo with the OpenGL renderer that supports hardware tessellation until there is a good Catalyst release. Unigine Heaven was released for Windows 7 back in October on this operating system's launch day using a DirectX 11.0 renderer, but buggy Linux drivers have held back the public Linux-OpenGL build...

    I hope when Fermi comes out they still won't be waiting for ATI to fix their drivers to release the linux version.

      Surely just releasing it and adding a check for nvidia drivers would pressure ATI into fixing their driver faster than not releasing it?

        Actually, last month it was stated that a "hardware vendor" was holding things up but failed to mention which one. At least that was from Unigine - phoronix has been filling in the rest all on its own. Is there any confirmation that it is currently ATI holding things up?
        I'm all for speculation, so I'm sure ATI's drivers are still holding it up, but I'd just like something a bit more official.

          Given that Phoronix and unigine are on pretty good ground dialog wise and phoronix also has a unreleased version of it I would say that the info that ATI is holding up the release is pretty good. Especially since ATI is the only vendor out there that currently has hardware that supports hardware tessellation.

            Well, again that's all speculation. I'm not completely up to speed on the opengl tessellation side of things, and it's also rational to assume that nvidia would like the demo to be released along with Fermi (they have after all been using it quite heavily to show off Fermi).

              Well not really,

              Unigine Corp's CEO, Denis Shergin, told Phoronix this afternoon that Heaven for Linux should be available in one to two months. According to Denis, the Linux build of Unigine Heaven is done, but they are waiting for new drivers to be released before pushing out this impressive tech demo. OpenGL on the AMD side is "way too broken" so it looks like Unigine will be waiting for the Catalyst 9.11 or 9.12 driver releases before pushing out Heaven. The Unigine Heaven Linux version will carry full tessellation support enabled, we're told.
              Notice the "way to broken" quote from Denis?

                Nvidia has been releasing videos of The Fermi with what appears to be a "1.1" Heaven build, so it's obvious that they do have the hardware and software to run it. Really, there is no indication that at this point it's AMD that's holding back the demo. Could be, but as long as someone at Unigine comes out saying just that, it's all speculation.

                  Did you not read the "way to broken" quote from Denis?

                    Don't get me wrong - I'm sure that's what's going on still, but the developers from Unigine delaying because they feel AMD's drivers aren't stable enough and AMD asking Unigine to delay it are completely different. It's the the whole being asked by a hardware vendor thing that's put some confusion into the matter, and I'm wondering if the article isn't more a conclusion reached by Michael from trying the demo out with AMD's drivers than by talks with Unigine.

                      Were are on 10.2 and on to 10.3. The guy was talking about 9.11/9.12 (and most likely referring to support found on earlier releases still). The drivers could have gotten better by now, or not. Point is that the quote is old and you really can't use it now; a lot in the driver has been fixed and even broken since those releases. I want a statement from either AMD or Unigine that says that as of now the drivers are too broken so Heaven on Linux has been delayed until further notice.

                        Considering that Phoronix is running the engine internally, makes mention of "Unigine Heaven on Linux internally and it's a beautiful tech demo / benchmark to say the least even without a bug-free tessellation experience. " and the only hardware out there right now is ATI's offerings then the mention of "We don't yet know whether the Linux build will make its public debut at that time or whether ATI Catalyst 10.3 for Linux will finally be the golden egg for Unigine Corp, but the Unigine Engine does continue picking up new features. " It doesn't take a rocket scientist to figure out what the delay is. To conclude anything but ATI holding up the release is wishful blind thinking.

                          But that's just the point - all of that information comes from Phoronix, not from Unigine.
                          I actually find it strange that AMD would try to hold up releasing the demo based on that they are the ones with a hardware tesselator out right now - and are the ones with an OpenGL extension for it. This particular extension has been around for some time now, and I find it also strange that Unigine are having issues with it - maybe they don't use it, as then it becomes more of an AMD specific demo (geometry shaders could be used instead). Or maybe they really are working with nvidia to have both AMD and nvidia code paths (for however nvidia are going to do things).
                          I remark upon the tesselator as it would appear that the demo would otherwise be ok to be released - but again information there is vague at best, so who knows.
                          AMD could well be holding it up for a future driver release, but I wouldn't blindly take the phoronix article's word for it. I'd rather draw my own conclusion from something a bit more official.

                            So what happens when you read a newspaper? Do you believe it's all rubbish until the first party admits it first hand?

                            Given AMD/ATI's openGL history there really isn't anything surprising here at all. If you need another example take a look how long it took them to show off UVD in linux.

                              Newspapers often do quote people first hand. Newspapers also have hot gossip sections where they make stuff up or just like to push their own opinion.

                              Actually AMD's history with OpenGL is pretty good (since the catalyst program started up) - as long as you stick to spec. And they've been getting remarkably better for when you don't. Which has absolutely nothing to do with UVD.

                              Really, I'm all for things pointing at AMD's drivers, but the article was an opinion dressed up as news; if that's the new direction of Phoronix, I'd suggest looking a bit more at how semiaccurate presents such things.
