    Am I the only who is HAPPY with the Mesa/Gallium/ATI stack? power management works here (with the echo power_profile stuff), all of my games work at over 60fps mostly 100+ (Using a XFX 6670 on a 4Ghz Phenom II x6), No crashes, where's Crapalyst crashed DAILY. So sure its fast but you have to put up with your system locking every so often (never happened here with the free stack)
    No, I'm also quite happy. Gallium runs stable, no more strange crashes etc. Only my laptop is a lot hotter with the current power management... But they are definitely on the right track forward!

      Gallium is stable as hell. The last time I tried Catalyst it caused constant crashes. One of my work machines has the Nvidia blob, and despite what some people say, it's not much better. I can be guaranteed of at least one crash a day, but usually more.

      If the Radeon driver can manage 30fps on the Valve games, I'll settle for that rather than dealing with the shitty blob. I don't have any issues playing 1080p video without acceleration on my machine, although that would be awesome for my media center. At this point the only thing I'd consider lacking for my own needs is better power management.

        I bought an AMD Vision laptop on march 2011. (VGA: HD4200 + HD5470)
        Nerds suggested me to buy AMD because open source drivers availability, wayland, etc etc (I studied Energy/Mechanical Engineering, not Computer Science or Electronic Engineering).

        I was an arch user and I'm stuck with windows:
        open-source drivers don't permit me to use laptop: it fries.
        catalyst drivers are buggy, don't work with latest xorg server versions, no hd decoding, hdmi not working.
        Bah... crapware.

          I don't know what you guys do with your machines. I run Catalyst 12.8 on my HD6870 and Catalyst 12.6 Legacy Beta on my laptop with HD3200 without any problems. No crashes, hibernate/suspend working, no problems at all.
          If I run the radeon drivers on my laptop I not only get 15-20C higher temperatures, but battery is also draining really quick, even on the low power profile. Unusable for me and other people with similar laptops).

            I'm quite happy with Gallium, it's annoying to have to manually switch profiles for power management, but other than that it is stable and great.
            I've written a "service script" so that I can simply "sudo /etc/init.d/ati {low, mid, high}".

            Though I'd like to improve the performance; Does anyone have info about improving performance, to get the most out of my card? or is there already a thread with such information?
            I've also read something about "floating point textures" or something like that, how would I enable it?

            I use OpenSUSE.

            I'd also like to add my thanks to the Gallium/Radeon/Mesa teams, you guys have done a great job!

              Well, when it comes to performance, here are my Xorg.conf options:
              Option "ColorTiling" "true"
              Option "SwapbuffersWait" "off"
              Option "EnablePageFlip" "on"
              Though I do agree a proper performance guide would be nice.

                FWIW, I'm completely satisfied with the current feature level.

                It's power management and performance I personally find lacking - in recent tests, the low-end cards were 2x-5x lower perf vs catalyst.

                  I dream of the day that bridgman will anounce in the forums that they will release the PM or an article by Michael confirming this.

                    hey already did and michael did too not 2 months ago but it missed the 3.6 timeframe so will probably land in 3.7 series or 3.8 if some bug is found.

                    use the article search and read the article since it will fix many issues with pm

                      Please don't be waiting for us to "release PM". There's a lot of PM info out there already, enough to make major improvements in the existing code.

                        Am i supposed to read this as "We reviewd the code and we can't release it" ???

                        As for the info sadly i am no coder and i cannot help.

                          Correct. Still working on it though.

                          Again, there's a lot of PM info out there now. This is just a couple of additional blocks.

                          PM seems to be an exception to the rest of the driver stack -- everyone seems to want it but hardly anyone seems to be willing to work on it. For most of the other bits it seems that every N'th user is willing to roll up their sleeves and make the code better but it's not happening here.

                              What other possible answer is there ?

                                I have no idea TBH. And i can't think of anything else right now after the day long struggle with my motherboard which still refuses to work as designed.

                                Anyway. Don't mind me. I just had high hopes for that.
