    The Mesa state tracker and Mesa core slow things down. Some state tracker optimizations are being worked on and that should make the performance a little better. The whole thing could be made faster if the classic driver interface was dropped and both the core and the state tracker were merged together and simplified. This won't happen until Intel jump over to Gallium. Intel are still doing the majority of work on Mesa, so we can't just ignore them.
    What great news! Go X.Org!

      No, that won't cut it. Compiz *can* do what you suggest, but this 'feature' is extremely userunfriendly and is thankfully disabled by default. If you disable compositing for fullscreen windows and a notification pops up, you are in for a flicker-fest.

      This is 2011 after all, even IGPs have more than enough horsepower to compose a 2 or 3MP desktop.
      It works fine in KWin

        KWin also flickers when enabling compositing. Curiously though, it does not flicker the other way around (disabling compositing.)

        If that could be somehow fixed, it would be a huge improvement.

          I bought a Radeon 9800 SE (The saphire atlantis one) and put it in my dual [email protected] ... AGP 2x

          It run compiz quite well... but games appear severly CPU limited lol dunno if its in the game or the driver though.

            i remember reading that they were not keen on making the jump
            Intel appear to be in love with their GLSL compiler and they want to generate code directly from the GLSL IR. I think they don't want to exchange that for TGSI, it would be like a step backwards for them.

              What problem? DXVA works like an charm for my HD3850 under Windows 7. I use MPC-HC and XBMC. Please node that the HD2 and HD3 Series can only decompress 1 Stream.
              PS: I Update my driver each month.

              --------------

              It's only a matter of Manpower. So great job to all OpenSource Driver Devs.

                Maybe if someone replaced Gallium TGSI with their compiler IR they might take another look. I guess at this point we're down to hoping VMWare might do that, since the OSS devs are busy working on drivers and Intel isn't showing any interest.

                  Wow, so r600g is usable? The Gallium feature matrix indicates otherwise, but it hasn't been updated in a few months. http://xorg.freedesktop.org/wiki/GalliumStatus

                  Good work, graphics-stack programmers!

                    I'm not sure about the r300 driver, but the r600+ drivers are quite CPU limited, and I think that r300g is too, at least at some things.

                      r600g is better at some things and worse at some things than r600c now, and most of the current effort is going into r600g.

                      r600g is faster, but less stable than r600c for me. I switch back and forth.
