    I love the CGA color scheme of these graphs. Very appropriate!

      HD4890 with both pcie_gen2 and ColorTiling2D enabled

      All running very nicely with my 3.3.6 kernel and radeon_drv from git. Can't tell if it's any faster, though.

        "and setting ColorTiling and ColorTiling2D to true within the xorg.conf."

        isn't a xorg.conf obsolete ?

        is there a commando for the .pam_environment file ?

        anyway just a explain how to activate this feature?

          It would be but certain people freak out when others are allowed to use their computer how they want. Freedom and all that rot obviously doesn't apply to using certain software.

            xorg.conf isn't and has never been obsolete. You use xorg.conf.d now, but the idea is the same. You only need to include the Device section for the graphics driver. Everything else is autodetected (unless you want to customize those things too and then you can include those in xorg.conf.d).

              True, but i use much more slower cpu, pcie_gen2=1, vblank_mode=0, "SwapbuffersWait" "0" and have more FPS. Must be a reason.

              Lightsmark 62 vs 128
              Openarena 0.8.8 22 vs 44
              Nexuiz 51 vs 76

                Can you test with openbenchmarking and upload link to your results please?

                  Why?

                  May be someone know: Why so big difference between propriatiry and opensource drivers? Something was not implemented or only not fully optimized...

                    The few developers are too busy writing the drivers to even think about optimization. 30%-60% speed is the maximum we can expect I guess.

                      PTS run from my livecd, so anyone can reproduce the results.
