    Phoronix: 13-Way AMD Open Linux GPU Drivers On The Source Engine

    For your viewing pleasure today is a 13-way AMD Radeon graphics card comparison when testing out the open-source Radeon Gallium3D drivers on the wide spectrum of ATI/AMD GPUs while looking at the performance for Valve's Source Engine with Counter-Strike: Source and Team Fortress 2. Given the imminent arrival of Steam Machines and SteamOS to push Linux gaming into its long-awaited spotlight, is AMD's open-source Linux graphics driver capable of delivering a reasonable level of performance?

    That's quite strange. I am happily using radeonsi on those games (as well as other Source games such as L4D2 and Dota2) with a HD 7870, although it is true that I have my mesa recompiled with llvm-3.4 (which solves quite a bunch of bugs).

    Source needs OpenGL 3, LLVM 3.3 only supports 2.1 with RadeonSI, OpenGL 3 support is in LLVM 3.4

    How do you update the LLVM?

    Depends on your distribution. On Slackware it is: Download the source, adapt the version number in the SlackBuild script, run it and install the generated package.
    On other distributions you will do that different, for example on Debian or Ubuntu just do a web search for "how to backport" or something similar.

    Why is 5830 magically performing better than 4890? I believe 4890 has more horse power than that cheap card.

    Its even easier in times of the build service. Go here:

    http://software.opensuse.org/search?...upported=false

    Choose your distro from the drop-down-menu (click on the wrench). Currently selected is opensuse 13.1. Then search for llvm or for whatever this package is called on your distro. Then download the package and install it (normaly by just klicking on it). For suse you even have these 1-click-install buttons online.
