np everyone does that.

Anyway I think I know why quake4 doesn't work: from your log -

/opt/quake4/q4base/paklibGL error: failed to load driver: r600
libGL error: Try again with LIBGL_DEBUG=verbose for more details.
libGL error: failed to load driver: swrast
libGL error: Try again with LIBGL_DEBUG=verbose for more details.

I suspect if you did run -

LIBGL_DEBUG=verbose quake4-demo 

That you would see something like -

.... ./libstdc++.so.6: version `GLIBCXX_3.4.9' not found ....

This is caused by there being libstdc++.so.6 in the quake4 demo dir that is too
old for mesa (well llvm to be precise).

Solution is to rename libstdc++.so.6 and libgcc_s.so.1 that are in  
/opt/quake4/ I guess, to something else which will make q4 use your system
libs.

             Bug #: 50450
           Summary: OpenGL does not work or works very slowly on Radeon
                    HD3850
    Classification: Unclassified
           Product: Mesa
           Version: git

        OS/Version: All
            Status: NEW

lspci

I have ATI Radeon HD3850 on AGP bus with Pentium-4 PC. I observe very strange
behavior of OpenGL applications:
KWin, qudos, doomsday run slowly even not with high quality settings;
Quake4 demo from ID site crashes right after map loading, just when rendering
starts i suppose, and X server crashes with it.
I attach my glxinfo, kernel config and lspci. Versions of used software are:
mesa, libdrm and xf86-video-ati from git, linux kernel kernel 3.3.5, X.org
server 1.12.1.
I think this is bug in mesa or xf86-video-ati related to my video card. Please
help me.

dmesg output and /var/log/Xorg.0.log would add more info.

If you use mime type text/plain for them it's easier for people to read the
contents in their browser.

I've got an AGP 3850, but it's not in a PC at the moment, when I get time I'll
put it back in an see if anything has regressed in the last few months.

With AGP it's quite possible that what works for me with the same card will
give you problems just because we are not using the same mobo.

quake4 console log

I attached Xorg log, dmesg and log of quake4, which crashes like i said.
Sorry for mimetype, i thought bugzilla auto-detect would work.

Thank you, it worked.
But still i can't understand why doomsday runs so slow, I think it must run
smoothly on my card. I also get weird screen artefacts in xonotic.

I haven't tested those with a 3850, IIRC nexuiz was a bit slow - but then that
was at 1920x1080 and reducing res/effects could make it playable.

I also never had the complication of a compositing desktop - maybe there is
something there to be tweaked - maybe not.

I don't know gentoo, or any distro (using ancient LFS). Are you compiling mesa
git or is gentoo - what options are being used?

I always used to test with vsync off, I can see from your xorg log that
swapbuffers wait is on. I don't know how/where you would add the xorg.conf
option in gentoo but in 

Section "Device"
Option          "SwapbuffersWait" "off"

will disable that.

In addition you need to run the app with the env

vblank_mode=0 

compositing desktop allowing that should disable vsync and gain a few fps

You could avoid using the env everytime by making/editing .drirc in your home
dir to look like -

<driconf>
    <device screen="0" driver="dri2">
        <application name="Default">
            <option name="vblank_mode" value="0" />
        </application>
    </device>
</driconf>

Another thing you could check is whether gentoo does anything with gpu power
settings.

cat /sys/class/drm/card0/device/power_method
cat /sys/class/drm/card0/device/power_profile

The only difference gpu wise between your logs and what I remember mine to be
is that your GTT is 64M. I used to use 256 - I have no idea if that will help
anything at all, but you could try in bios settings increasing AGP Aperture
size if you wanted to change it.

Does passing radeon.agpmode=-1 on the kernel command line help?
