    we also ran this latest driver stack (Linux 3.0 + Mesa 7.11-devel) when disabling Swapbufferswait and enabling color-tiling


    No, seriously. I agree that you should run more demanding benchmarks because when everything is 60+ or even 100+ fps nobody really cares how fast it really is.

    It would be interesting to know if the issues that bring the fps down so extremely as in nexuiz go away if you run it without compositing. But in earlier benchmarks the performance was slower when not using compositing with open source radeon...

      Provide extensive documentation in an easy to access form and more users might do just that.

        Like Doom 3, ETQW, etc? Don't be silly, they very much run well...

          i just searched for documentation of profiles or at least some profiles to understand them
          but i just found "~./phoronix-test-suite/pts-core/definitions/test-profile.xml"

          is there some kind of tutorial?

            Nice colors for the charts... blue, green... blue... and green!

              Within PTS 1.x/2.x or PTS 3.0 (it's temporarily gone in Git) within documentations/ there should be a "writing your first test profile" HTML guide. But it literally is quite simple, the most effective guide is just looking at an existing test profile such as that for padman or doom3. From there you can simply copy and paste and then alter a bash script or XML file. I'm also always in IRC and more than happy to guide any motivated individuals... About 5 minutes of teaching and you can easily write your own test profile for almost any app.

                xorg.conf

                Dear Phoronix, can you share your xorg.conf for Ati R600 drivers and other tweaks in config files if need it, pleas? I'd like to try it myselft on non-production PC with Xorg edgers PPA and linux 3 kernel debs from Ubuntu PPA.

                Thank you

                  don't use Xorg edgers PPA or ubuntu PPA if possible, compile your own kernel to get rt functions online (it helps a bit) and compile mesa/drm/ddx from sources with -O3 (it helps a bit more in some scenarios). Beside compiling mesa from sources you can get st3c and float textures + other goodies missing in xorg edgers

                    The options used are just "SwapbuffersWait" "false" and "ColorTiling" "true" in xorg.conf. And you can add S3TC support with any release/repositry of Mesa. (Float textures does need a recompile. Dunno if any of the Ubuntu repos enable it.)

                    As for adding optimisations or using anything other than the default kernel your distro provides, I think a [citation needed] should be used...

                      https://bugs.freedesktop.org/show_bug.cgi?id=37168 is fixed, so now I can use r600g full-time Awesome!
