    Phoronix: Half-Life 2 On Wine Is Faster On AMD R600g Over Catalyst

    Here's an interesting finding: at least when running under Wine, Half-Life 2 is faster on the open-source AMD Radeon Linux driver than when running on the proprietary Catalyst driver. There are also some other similar results where these Windows games have the advantage when running on the Gallium3D open-source driver.

    Amd catalyst data missing.

    Graphs do not show Catalyst data at all. (PS can you add "report bug" or something to your site?)

      Do you even read that crap before posting? Like the description below each pic? See the nonsense in it?

        Is this to Michael, or przemoli? I see ati-glsl and ati-arb. Which one is r600g. As far as I know Catalyst and Mesa support GLSL and ARB extenstions? Thank you very much for the Doom3 64 bit port. It is awesome

          Well, to Michael of course...
          Just like you mentioned it's not clear what ati-glsl and ati-arb represents. The description for 3dmark2001 implies ati-arb is catalyst, while others like hl2 claim the opposite.
          And then we have the hilarious heaven and clear_d3d benchmarks, where the graphs show almost no difference but the description mentions huge advantages.
          I'm not sure how much more you can get wrong in a benchmark article :P

          Oh, and thx

            800x600 as res used for all tests? Most be a joke or?

              As clearly stated in the article, the Catalyst result is the one at the right end of the graphs. Glsl and arb have nothing to do with the driver. The text makes perfect sense to me...

                I'm sorry, but "clearly" is wrong wording. The labeling is very confusing and also: the last two result seemed to be Catalyst, according to the first page, not only the last one.

                  Yes the two last, as in the blue and the green dot to the fare right. I agree that this isn't the best organised test results, but if you read the artical you will find that Michael wasn't the one who set up this test.

                    Wait, how are these tests CPU-limited? It's a freaking Core i7! With four cores, 2.8GHz each, and hyperthreading!

                      I have noticed this with starcraft2. The open source drivers tend to work better then the catalyst. At least for me.

                      ..

                      I think that part of the deal is that the 'highly optimized' nature of catalyst is often on a per-app basis. In order to look good in benchmarks AMD has spent considerably money profiling and creating optimized code paths for specific applications. If you are not using a particular gaming engine or application that AMD didn't anticipate or put a lot of effort into optimizing then the open source drivers are going to be more competitive.

                        Oh, now I see it. Still confusing though :P

                          I doubt that. r600g doesn't have a shader optimizer, how possibly it can beat Catalyst?

                            I very doubt that, either. In clear_d3d test text below is saying r600g has much better performance than Catalyst, but all see is virtually overlapping grapths. WTF?

                              The two graphs are not r600g vs Catalys, it's two modes in Wine, the Catalyst is the spike at the end of the graph, the rest of it is r600g on different versions of Wine.
