    I'm assuming by legacy, he means the hardware which is no longer supported in the latest versions of Catalyst.
    According to the article it would drop support for ALL Catalyst users, even with new hardware (like HD7970), because they use it as OpenGL 1.x for speed reasons. See the quotes in the article.

      And how many tests have been run that actually use the new GL3 code?

        Since the entirity of the Phoronix test suite worked with code that ran under Mesa versions prior to Mesa 8, it is clear that none of the software uses the new OpenGL 3 capabilities of Mesa.

        However, it is entirely possible that some of the software (especially games) could detect that it was running under non-mesa stack (fglrx), and hence automatically switched (when using the proprietary driver) to utilising more advanced OpenGL features.

        It may well be that the Phoronix suite in some cases merely reports on the difference between OpenGL 1.4 versus OpenGL 3 or 4, instead of reporting on the differences between Mesa and fglrx.

          Yes! Remove old crap!

          Stop supporting it and some people will realize they live in the past century.

            And this is the problem with Open Source concepts. There needs to be assigned project deligates, who promote and request movement for the project teams, to say AMD, or to promote more open coders to come in.

              Even though I'm a fglrx user, I can't say I care about that a whole lot, since for me fglrx has been corrupting the screen when KWin compositing is on anyway (black screen areas due to their new Direct2D implementaion)...

                I'm not sure what you think Open Source concepts has to do with fglrx. It's about as closed a project as there is.

                  Not anytime soon

                  On the blog:

                  the current code will stay at least for another year
                  I'm not 100% sure what that means - it's probably just referring to the January 2013 release, since the one for this summer is already branched.

                    This is a bad decision and I don't support it. Thanks for moving backwards.

                    Drop fglrx, and I will drop KDE. hmm yes maybe its time to move on.

                        Obviously I was talking about KWin, even though that propitiatory.

                          This position doesn't make any sense. KDE runs superbly well with the open source Radeon drivers, and it runs very poorly with fglrx.

                          You are, in effect, threating to drop KDE unless it allows you to stick to experiencing abysmal performance.

                          Frankly, I don't get it.

                            Kwin isn't at all proprietary. The open source Radeon drivers aren't proprietary. The Kwin project can hope to have some sway over the open source Radeon drivers.

                            fglrx is proprietary. The Kwin project has no sway over it whatsoever.

                              Stop being a fan boi. The fglrx drivers are the fastest, probably 4x the speed of the open source ones for 3D. Not to mention they are more compatible with Wine. I'm all for the open source drivers improving but they need to get their features rich before people are going to want to use then as a whole solution.

                              Weigh up the situation:

                              * Linux dev should always aim for the fastest speed, the smallest footprint, and the most features.
                              * Will the change to drop 3d OGL1 be a bigger improvement then the lost speed of fglrx drivers.
                              * How long will AMD-ATI users be disadvantaged under KDE.
                              * How many users will KDE lose, considering the people that like AMD-ATI are the same types to like the sophisticated offerings of KDE.
                              * Could Trolltech do a survey to fathom the user base between Nvidia, ATI, Intel.

                                Stop being a fan boi. The extremely minor segment of the Linux user base who are gamers is **NOT** a good reason to want to cripple KDE desktop performance.

                                ATI/AMD users are **NOT** disadvantaged under KDE, in actual fact they are users who enjoy the best value-for-money performance of Linux desktop software under KDE.

                                As for your comment "Linux dev should always aim for the fastest speed, the smallest footprint, and the most features" ... Linux devs do in fact do just exactly that. Their effort so far is the Radeon open source driver, not fglrx.
