    Default OT - 4770 performance?

    About two years ago I bought a Sapphire 4770, it looked really good on paper (still does) but the stock Fedora sw doesn't impress me particularly, are you able to say what is the state of open drivers for this card?

    ps will dress in black if it helps...

    and the amazing stuff is that my integrated 4250hd card hit 30 fps in ultra on nexuiz at 1440x900x32 lol and my 4850 is always closing the 90 ish fps at 1680x1050x32

    i think there is something nerfing the fps on the phoromatic test cuz the difference is too big

    my 4250 run standard xorg edgers packages with color tiling and swap buffer off

    my 4850 run hand compiled stack with custom cflags including -Ofast (yeap i have gcc 4.6 o_O)

    in both machines i have 2.6.39 kernel hand compiled for preemtive desktop and 1000hz + some goddies that the ubuntu kernel disable by default

    Is there anywhere documentation about how to enable/disable those things??

    It is so hard to find useful documentation on all the radeon settings/configuration/features.

    Something is off.. Quick comparison with my 5750, AMD X2-545, natty with gnome classic (unity disabled), using 2.6.39, with git of mesa/ati/libdrm..

    Perhaps someone could benchmark numerous configurations with different non-standard options (Unity on/off, vsync on/off, etc.) to determine how much each helps/hurts and what the real best-case framerate is?

    Emphasis mine.

    Thanks for posting that -- I just got a 5770 but can't test it yet, and those benchmarks had me a bit worried.
    Your framerates seem to be increasing with the resolution -- is that usual, or a sign of an error? Your screen resolution is listed as 1280x1024 -- if that's the monitor's limit, would it cause inaccurate results from the higher-resolution tests?

    If the results are all right, though -- 58% of Catalyst* at 2560x1600 in OpenArena!

    *on the Phoronix system. I'm assuming Catalyst is doing some AA and anisotropy too.

    No. OA doesn't even have an option for AA IIRC, and AF is not the default.

    This comparison seems about right to me. I have this laptop that has both Intel Core i5-450M CPU/GPU and Radeon HD 5650 GPU. I have been using the latest git kernel/libdrm/mesa/ddx code ever since Evergreen support was initially released.

    So here is my sad comparison:

    With Intel GPU when Radeon has been soft switched off I get:
    + Usable desktop and video performance
    + Acceptable 3d performance (for a low end card)
    + Usually stable (but not always)
    + Computer is cool, fans hardly spin
    - HDMI output is not supported (due to laptop HW limitation?)
    - Some minor glitches

    Instead with r600g when Intel has been switched off I get:
    + Usable desktop and video performance
    + HDMI works
    - Always horrible 3d performance, worse than Intel (I test glxgears in fullscreen 1920x1200 and use Blender, usually not games)
    - 3d is often too unstable for work (Kernel or Xorg crashes while using Blender), but I have seen nearly stable setups too. Mesa 7.10.x could be more stable.
    - Computer runs hot and fans usually spin loudly (This probably happens on Win7 too. I sometimes try tweaking power_method and power_profile but they don't make enough difference)

    Obviously most of the time I end up using Intel. But often after git pull I test r600g. Unfortunately I haven't seen it beat Intel yet.

    Well compiz is atleast on, i just can't deal with the unity desktop..

    [/i]
    Usually when testing, 1280x1024 always seems to be greater fps then 800x600 in openarena, but something changed in mesa this last week..

    I can't test the 2560x1600, but i tried an older crt monitor, same results:

    (gateway/samsung vx900 1600x1200 max..)
