    Default The Major Open-Source ATI Improvements Over Two Years

    Phoronix: The Major Open-Source ATI Improvements Over Two Years

    The open-source ATI/AMD Radeon Linux driver stack has made a lot of improvements in recent times with their Gallium3D drivers becoming mature across all generations and support for new features (such as DRI2 page-flipping) landing in the mainline code and beginning to make its way to users. The time required to bring up support for new generations has also been reduced greatly and with the Radeon HD 8000 series there should be a turning point for their open-source strategy. In this article, we are providing an updated look at the course of the open-source driver's performance for the past two years.

    This would be so much better if there were screenshots from each benchmark.

    Because now we don't see whether these "regressions" really were regressions or if they just rendered more details etc.

    It also would be nice to see whether or not some commercial games like UT2004, QuakeWars or Heroes of Newerth are working and if yes, with what quality of image.

    We have never any feedback on the few commercial title that exists on Linux. I'm waiting for those title to work with opensource drivers to swap from catalyst to open-source.

    Could it be possible to have such review?

    I don't have the games you are referring to, but there has been lots of feedback on the commercial titles, just check http://wiki.x.org/wiki/RadeonProgram

    Personally, I have played the following commercial titles using r600g:

    Doom3 + RoE
    World of Goo
    Aquaria
    Penumbra trilogy
    LugaruHD
    Gish
    QuakeLive

    Stuff like Doom3 is playable, even on low-end hardware, but obviously much slower than with Catalyst.

    Quake4, QuakeWars and Heroes of Newerth are all reported to work. The only commercial "games" currently not working seems to be the Unigine benchmarks, which have just started working on r300g, but not r600g yet.

    I find it amazing that r300g is consistently above 3/4 of the Catalyst performance now, often even faster. That's all anyone can ask for, and a huge success for the open source community.

    Mind-blowing. We are just a step from throwing those ugly blobs away.

    So true. However, there are some flaws like the lack of out of the box s3tc texture compression in Open Source drivers. I'd also like to see performance comparison in more demanding games like UT2k4, Quake 4. If OS drivers will keep performing well, then blobs can go home.

    Quakewars doesn't work with git r600 (HD4650), even though s3tc support has been installed.

    Heroes of newerth works really well, with no artifacts and medium graphic settings. The game is as playable as it is with catalyst (just with a bit lower graphic settings)

    Today, there is only one blocking bug to play etqw with r600g. And of course a lot of performance improvement needed.

    Thanks to pingufunkybeat and tball for those answers.
    However, I really like Michael to write (and keep updated) something giving the comparison between open-source and catalyst, so the end-user that I am can see what areas are supported and what others needs to be improved on open-source side.

    I'll visit the link given by pingufunkybeat though, this should partially answer the point.

    Thanks.
