    Its been said before, but man, we have really got to get some non-FPS, and some non-video game 3d benchmarks.

    Not that the results of a few different game engines aren't interesting, but the story that we get from these data is pretty narrow.

    My recollection was that one of the attractions of the 300g driver was that it could support a number of apps which did not run on the 300 classic mesa driver. I understand that's hard to show on benchmarks (unless 300c gets a flatline) but worth mentioning.

    Weird how only OA regressed from playable to not. Is this the 50% drop that we also see in glxgears, from the extra copy of DRI2?

    Beside not doing better than the tradional mesa stack, as I have told earlier the Gallium 3D is still really unstable, causing lots of freezes (almost daily) with my Mobility Radeon x700 (RV410). Since I rolled back to mesa 7.7, no freezes at all for the last 15 days (uptime). To me, it seems quite obvious which one to use right now...

    Phoronix: ATI R300 Mesa, Gallium3D Compared To Catalyst

    Last quarter we compared the Catalyst and Mesa driver performance using an ATI Radeon HD 4830 graphics card, compared the Gallium3D and classic Mesa drivers for ATI Radeon X1000 series hardware, and ultimately found that even with the ATI R500 class graphics cards the open-source driver is still playing catch-up to AMD's proprietary Catalyst Linux driver. In this article we have similar tests to show the performance disparity with ATI's much older R300 class hardware. Even with Radeon hardware that has had open-source support much longer, their drivers are not nearly as mature as an outdated Catalyst driver in the same configuration.
