    No doubt about it. _But_ I will never be running crysis on my Radeon 9700 anyhow.
    try the no backfill patch for the xserver
    it will increase your composited desktop performacne drastically.
    Say where do I find this patch and how do I apply it, some sort of guide is appriciated.

      if you are using ubuntu karmic, just add this ppa and update:
      https://launchpad.net/~launchpad-wey...ver-nobackfill

      if you are using debian, or lucid, or for some reason you want to compile it yourself:
      https://bugs.launchpad.net/ubuntu/+s...6/comments/256
      just change the xserver version numbers accordingly.

      i dont know how to do this in other distros, but im positive somebody else in this forum will help you out with that

        Thank you for the help, I will try it out once I get home.
        Interesting, this may result in Gnome-Shell actually working on my newer computer. Not that it works on the 9700 really, a lot of graphical defects.

          just to make sure we talk about the same thing.
          this will increase your desktop performance with fglrx drivers.

            Yes pardon me for my inconsistency.
            Gnome Shell is currently not working correctly on either of my ATi powered computers. The one older with a Radeon 9700 and the newer with an HD4850.
            This patch will as you say hopefully bring up performance on my fglrx powered HD4850, possibly to such a state so that even Gnome Shell runs smoothly.

              The patch did not seem to work a whole lot.
              Well well, it was worth a try atleast.

                compare latest gallium3D and proprietary drivers

                hi,

                it would be great to see a side-to-side comparison of the latest gallium3D enhanced open-source ATI drivers against the proprietary ATI drivers on something like an ATI Mobility Radeon™ HD 5470.

                cheers

                  There is no such thing called "gallium3D open-source ATI driver for Evergreen" So it won't be possible...

                  In detail:
                  R300-R500: classic dri driver and gallium driver
                  R600-R700: classic dri driver; work in progress for gallium driver
                  Evergreen: nothing (I guess it's being worked on also)

                      evergreen support is included in the r600 classic and r600 gallium drivers.
