    Phoronix: How The ATI Catalyst Driver Has Matured Since The RV770 Launch

    It has been two years since the ATI Radeon HD 4800 (RV770) series launched so we have gone back since that monumental hardware launch and have re-tested each Catalyst driver release since then to see how the performance has changed for the ATI Radeon HD 4850 graphics card. The Catalyst driver has certainly matured over the course of two years in speeding up the OpenGL performance with this hardware along with bringing new features to their proprietary driver, but it is not exactly smooth sailing.

    hard regress.... dont like it. I changed 1 month ago from FGLRX to opensource drivers, 3d is still buggy, but 2d owns, plymouth works ok[with fglrx doesnt] and many good stuff for opensource drivers

    i have 4850

      Thanks Michael for this comparison. It is quite informative :-)

      So there is a noticeable regression on 3D performance for 10.6 hmmm...
      Is this because of the 2D engine change?

        possibly. There's only one way to find out: Michael, can you re-run the 10.6 tests with A2AA disabled? Or did you already wipe the test-rig?

          Very nice comprehensive test. Thanks a lot!

          It was a nice find for ETQW.

            I just can't wait that OSS stack can handle properly any kind of games, to get ride of fglrx.
            What annoys me most in fglrx is video tearing.

              What annoys me most is the way that for the OpenGL beta 10.3/10.5/10.6 versions there's been horrible OpenGL bugs on the Evergreen cards that make certain games segfault on lauch or run slowly on 4 series cards. Even more annoying is that I'm pretty sure the bug was confirmed for 10.5 and announced fixed, but the fix didn't make it into 10.6.

                Sadly, when running linux, buying latest hardware can be deceiving, as manufacturer either don't give any driver and/or any testing device for the kernel devs to develop a driver.
                More deceiving as we should attempt from AMD a premium handling of latest cards as they are particularly friendly with Linux / OSS world.
                Nvidia is no better, as it took ages for their binary blob to drive the 8800 2 or 3 years ago, when those cards were ruling the 3D worlds.

                Let's hope that with OSS stack and more unified code from fglrx side, this bad story won't happen again...

                  Tons of regressions illustrated via those tests. And you expect the Evergreen cards to be 'working' when the older cards aren't performing any better than older drivers (e.g. 10.5)? If you don't mind, poor 3D with FOSS drivers, then get ATI?

                  'Wish I didn't read that article..

                  I've been told by a few ATI *owners*, in particular HD 4xxx owners, not to bother and go with Nvidia. I heard good things with the 10.6 drivers but those aren't evident in those tests.

                    don't waste your time on the past the future will be more successful.

                      Those tests were all at 2560x1600 and still delivered playable frame rates, so I'm not sure what your problem is. Or perhaps you are one of them who gets totally depressed if he don't get 10000fps in glxgears?

                        ++ thats it!....

                        but yes the opensource driver need some more love.

                          That's one thing I do agree with you on Qaridarium, that ATI will at some point in the future be an excellent all round choice for Linux users. For both those who wish to use the FLOSS drivers or fglrx.

                          But, and it's a very big but... What Panix, and I, and others are concerning ourselves with, and what stops us from buying ATI cards at the moment is that we need to live in the world in which we live in at the moment. We can't teleport into the future.

                          We evaluate on what functionality and experience we can expect right now. I'm fairly confident that ATI cards have a very bright future in the consumer graphics card space for Linux users, so much so that I continually find excuses to put off a card purchase on the basis of seeing what new stuff is happening on the ATI front, waiting for fglrx to become water tight. I might be vocal about its flaws as they are now, but you can see that they're putting effort into it and with effort and customer feedback it only stands to reason that things will improve to the point where nVidia have a real fight on their hands.

                          So you may wonder why people aren't prepared to buy on the basis of possible future functionality and performance, but some need their machines to perform right now.

                            you can't ? sorry for that.

                            do you need some help to fix your problem ?

                            To buy hardware is all about the Future because you don'T buy the hardware for the Past and the here and now is the past tomorrow!

                            do you want to be wrong tomorrow? do you want to be wrong in the future with your hardware buyed right now?

                            To buy Nvidia now is the biggest mintage of a investment for the future you can do!

                            do you wana be that stupid?

                              Nuthin stupid about buying stuff that works right now. I did just buy a new graphics card. I hope I didn't do anything silly.
