    Ah!

    I had OpenArena slow down to the crawl and hang on me too. I guess I'm experiencing the same issue as everyone else then?

    No; as Fran points out, you've described a memory leak. A race condition is (basically) when an error can be caused by related events happening in an unexpected order. It's called a race condition because the outcome depends on which process/signal/event "wins the race". The solution is usually to either explicitly force synchronization or to tweak the system such that the appropriate process is guaranteed to "win" (the latter tends to be used in hardware, where delays/sequencing can be built physically).

    Cooper has pushed a patch which should help with the corruption which previously forced you to run "indirect" (eg openarena). Haven't tried it myself yet though.

    Doesn't help me. See http://bugs.freedesktop.org/show_bug.cgi?id=23469

    I can't believe things are moving so fast Is it Google earth working already?
    Bridgman, I always wanted to ask you something...as you a working in AMD, can your team exchange if not code, but ideas with fglrx team.

    We discuss ideas with the proprietary driver team (not just fglrx) and pick up code snippets for programming specific hardware blocks. What we don't do is pick up million-line code blocks and try to fit them into a 20,000 line driver

    Why is fglrx SO huge?

    Because it covers all the chipsets? Because it implements its own memory manager and half of X Server? Because it implements all of Mesa basically?

    I mean, the new open source 3D drivers are looking mean and lean, other than the spread among Mesa/DDX/KMS/GEM etc, I don't see where the discrepancy comes from.

    Probably because it is full of

    switch (app) {
    case IDTECH3:
    ...
    case IDTECH4:
    ...
    case MAYA3D:
    ...
    case GLXGEARS:
    //uh!
    case BIGKNOWN3DBENCH:
    //100000 line of code
    case ...
    }

    take a peak at nvidia's driver then you'll see that fglrx (the kernel module) isn't too big at all

    I guess it's that big because of what Mickabouille worte - optimization for all different kinds of apps

    @Drago:

    last time I tried (some days ago) there still was massive corruption with it
