Since the last update of Xorg stuff, including the

The bad performance also occur with the recommendations made in
ports/UPDATING for driver radeon. Without those recommendated adding
of options even with a working xorg.conf file the performance stays worse.
The recommendations have been removed from UPDATING; with the exception of the
DynamicPM option, all the others are at their default settings and therefore
not necessary.
All right, I already adjusted my xorg.conf towards the initial state ...
Worse means: using vlc (also after recompilation after upgrades made!),
videos are massively bumpy and can not be watched with vlc-screen fully
expanded to 1900x1200 pixel with HD4830 graphics card - this worked
perfectly before.
Check out the logfile '/var/log/Xorg.0.log' if you see anything unusual.
Well, for the untrained eye there seems nothing wrong, except the
non-existent acceleration ... see below.
Moving windows around now looks like having chunks of video content
floating around - as on unaccelerated/slow graphics boards.
When looking at the logfile '/var/log/Xorg.0.log', does it say the following;
(II) RADEON(0): Acceleration enabled
(II) RADEON(0): Set up textured video
I see this:
(II) RADEON(0): MC_FB_LOCATION : 0x00ef00d0 0x001f
(II) RADEON(0): MC_AGP_LOCATION : 0x003f
(==) RADEON(0): Backing store disabled
(WW) RADEON(0): Direct rendering disabled
(EE) RADEON(0): Acceleration initialization failed
(II) RADEON(0): Acceleration disabled
Personally, I have built this port with one of the patches removed. In my case
the patch in question hung my machine every time! (there was quite a large
thread about it on the mailing-list) Try removing the patch
/usr/ports/x11-drivers/xf86-video-ati/files/patch-src-radeon_driver.c and
re-install the driver. If that works you can make the change permanent like
this:
# cd /usr/ports/x11-drivers/xf86-video-ati/files
# truncate -s 0 patch-src-radeon_driver.c
# chflags schg,sunlnk patch-src-radeon_driver.c

Well, yesterday or two days ago there was a change of the port
x11-drivers/xf86-video-ati. The file patch-src-radeon_driver.c has gone.
But the problems still occur (but not that harsh as before). I realize
on all AMD driven graphicsystems this bumpyness, even on those
graphics cards, HD4830, which are supposed to deliver a acceptable
performance for every day's usage, show now a kind of being cut-off and
they are no longer faster than the crappy HD4670 or HD4770 which we also
use in some FBSD 9.0 boxes.
