    ati-glsl and ati-arb are wine settings.

    just look at the far right for the catalyst results, all the others are r600g.

      What a useless bunch of crap! Why Michael decided to post this is beyond me. He could have at least took the results and reformatted them to make some sense in the graphs

      So far there have been more comments on the terrible graphs than when they're supposed to be displaying

        No, the two points rows in the first page are for the two lines with arb and glsl so just one point of the x axis is the catalyst driver, eg the last one.

          Which boggles my mind completely. Because I don't see how
          What we are looking at is the result on the far right side, which is the fglrx/Catalyst performance while the rest of the results are from Wine on the Radeon Gallium3D open-source driver.
          could've been written any clearer.

            Unless he means, WINE has CPU issues when using AMD drivers, I disagree. WINE had no CPU bottlenecks in all games I played (NOLF2 and stuff).
            Still, even with 800x600 this shows open driver has no resolution-associated CPU issues, which is good.
            Running 1920 parallel would be good though, even if opensource looses.

              I'm surprised that blizzard games aren't in there. I do believe all 3 current blizzard games are the most played ones, if not the world, at least under Linux?

                I think he might be refereing to that Wine it self dosn't do a lot in GPU space so optimizations are focused on CPU and there for his test is also set to mainly stress CPU bound functions.

                  Ha, yeah, I think what you're seeing here is a bunch of people who glanced through at the charts without reading the text beforehand.

                  The charts on their own were a little confusing if you didn't bother reading the explanation.

                    That would explain a lot of the comments on phoronix in general.

                      Then again, it's somewhat understandable that people don't read the text, because it's usually a pageful of filler crap and self-promotion.

                      So in a CPU limited test, the driver with less CPU intensive shader optimizations wins? Surprise.

                        Not exactly true. r600g uses the common shader optimizations, which are part of the glsl compiler. Only the hardware-specific optimizations are missing.

                        Also, if the bottleneck is on the CPU, the speed of the GPU usually doesn't matter.

                          Shader optimizations have nothing to do with this. Shaders are usually NOT compiled in the middle of rendering (if they were, there would be stuttering).
