    I dont know how Michael manages to get so low framerates in OpenArena with nouveau.

    Even my nv47 card is able to do a constant 90fps and I saw no performance regressions there in the last half year. And this 90fps top is likely caused by Xorg host taskswitches, not the card maxing out.
    I sometimes wonder how proficient Michael is at compiling things from source properly

    Was there not an article last year where Michael slammed Intel for driver regressions that were in fact caused by him picking up an old libdrm?

      The difference in tests also varies to great degree.
      Maybe there is a lot of unimplemented hardware features and 1800 is card which arch have got most of attention?..
      r600g driver is not working truly right in performance section: hd3850 is usually performing faster than hd4830 and hd5750. hd4830 has just two times the processing power than a hd3850. hd5750 have more than two times the processing power of a hd3850 and some more memory bandwidth and still performing worse.

        So what? Phoronix can still benchmark them.

          Benchmarking those games without S3TC and direct rendering is pointless, which means you must have a 32-bit linux with libtxc_dxtn.

            There are still a number of features that have yet to be implemented in r600g:
            - fast clears
            - 2D tiling
            - hyper-Z

              Not to be picky, and I know that high-end cards can be extremely expensive and that you only get a few free samples here and there from manufacturers, but:

              What's the possibility of also testing high-end cards in the latest 3 generations? For example, Radeon HD4850 or better, HD5850 or better, HD6950 or better. For the most part I have only seen low-end cards in your tests lately, some of them are even passively cooled because they've had so much of the bulk of the card stripped out.

              I'll use OpenBenchmarking.org (once it's launched) to see how the high end compares, I guess, because that's where I mostly shop. Unless I'm in the market for a low-power mid-sized laptop with a (small) discrete GPU, which I'm currently not, I would never, ever, ever buy a low-end GPU. For my desktops I would at a minimum get the high-end single-GPU solution, but more likely I go for the dual GPU cards out of preference. I just buy them infrequently, and use them until I need to run a program that won't run without the next-gen features

              One other thing: Can you offer incentives to people who run phoronix-test-suite and successfully submit non-outlier data into openbenchmarking.org? For example, you could have a drawing to give away a free HD5850 to one lucky person, randomly selected from the list of people who submitted their results for a given test suite and had their results accepted into openbenchmarking.org. Having events like this occasionally would give you a nice burst of data flooding openbenchmarking.org, and having a large data set is key for people to have confidence in the reliability of the data.

                  Earlier today I actually tried doing a comparison of classic Mesa, Gallium3D, and Catalyst on a Radeon HD 4890, Radeon HD 5770, and Radeon HD 6870. (I finally got a Radeon HD 6870.) But the Linux 2.6.38 Radeon DRM as of this morning fails to light up the display for the HD 6870.

                  We've already been working on a competition and hope to be giving away a complete Linux system from a Linux-friendly vendor as part of the OpenBenchmarking.org launch yet, but that sponsorship isn't finalized yet.

                    Yeah, nobody except Q cares about ta-spring.

                    I forgot r600g still doesn't support ST3C, so you're right that it wouldn't be useful. Still, it would be nice to see that for an r300g test.

                    Michael, can you clarify what Phoronix's position on that is? Are you afraid of getting sued if you publish an article using ST3C? I seem to remember some a long time ago, but perhaps not.

                      Can you explain ? You mean libtxc_dxtn cannot run on 64 bits ? Sorry if I misunderstood.
