    I personally encountered X freezing using the Heaven benchmark, so hopefully that was fixed. I have a crossfire setup though so maybe there was something there they didn't test.

    I experience freeezing/hangs and image corruption right at the login screen, and then if I'm lucky after running any 3d app like glx gears on Ubuntu 12.04 with my 7950.

    Default still the same ...

    Still the same mistakes as in 13.8 beta1

    1. Problems with access to /proc/ati - I made a patch from diff `s colleague Kolasa [publish below], and manifested that, of course, just like before - lack of access to resources by other non-root user:

    so before applying the patch:

    catalyst-13.8-beta2-broken

    as well as the application patch:

    catalyst-13.8-beta3-ok

    2. Still slower - the last working perfectly 13.3 beta3 [my build 4 provided by our NeteXt'73 - working together with kernels 3.11.x]. Here the AMD APU E-350 lost productivity from 10 to 17%. Tested on Xonotic, LFS [running under Wine] CS: S, L4D2 - this native games.

    3. The issue of memory leaks - so far not noticed but I am researching.

    4. The rest is running fine.

    5. Here the link to the patch - fglrx-13.8-root_proc-fix.patch

    Further tests and see that L4D2 works better ... but I do not know if it's "fault" of the last update the game or drivers as ... and I have not noticed so far also memory leaks ... but unfortunately there are still freeezing/hangs example during animation KDE ... or in the game - of course I have turned off vsync. At 13.3 beta3 that you will not find that.

    Default OpenGL

    What about OpenGL 4.4?
    They just added OpenGL 4.3 support now?
