Description Tomasz Jarzynka 2005-01-14 09:25:39 UTC 
Hi,

3D video rendered with my Radeon Mobility is very slow.
I've come across another similar report on the net, but found no solution.

I own an IBM Thinkpad T40, my friend does as well. The only difference between
the two is apparently the graphics card - I have Radeon M6 LY
and he has M7 LW if I recall correctly. We both have a similar
Linux configuration, with 2.6 kernels, X.org 6.8.x (6.8.1-6mdk for me) and agpgart
(both cards get initialized at 4x mode).

There are no errors reported by dmesg or syslog that I could relate
to this issue, still I get ~300fps in glxgears, and my friend gets ~1000fps.
A triple boost can't be caused by a minor design enhancement...

I also seem to have all the proper modules loaded (see the
output of glxinfo attached).

What is going on here? Why is 3d performance so sluggish under X?
The card works well with Windows.
Is this issue known at all? If this report is a duplicate please
excuse me, but I searched the db and found no similar reports.

Ummmmmmm... what?
Comment 2 Tomasz Jarzynka 2005-01-14 14:01:24 UTC 
Okay, 
to be sure I downloaded the latest CVS head. 
Everything loads OK, but I still get 275fps. 
Please, shed some light on this issue, please...

Comment 4 Christian Kellner 2005-07-22 09:04:14 UTC 
I also have this bug here. It is very annoying, if I can do something to help
here please let me know. Thanks!
Comment 5 James Le Cuirot 2006-01-12 20:43:08 UTC 
Not sure if your card supports it but try putting this in /etc/drirc.

<driconf>
    <device screen="0" driver="radeon">
        <application name="all">
            <option name="hyperz" value="true" />
        </application>
    </device>
</driconf>
Comment 6 Roland Scheidegger 2006-05-07 05:19:05 UTC 
I am not exactly sure what the bug here is? M6 is a low-end device. You can
boost performance if you enable color tiling (enabled by default with xorg
6.9/7.0), enable page flip (in xorg.conf) and hyperz with driconf. (16bit depth
would also help.)
As for the M6-M7 comparison, this is NOT a "minor design enhancement". M6
corresponds to a radeon 7000, M7 to a radeon 7500. M7 has (depending on the
exact clocks, I believe they can vary a bit for the mobile parts) twice the
memory bandwidth, roughly 3 times the raw rendering performance (2 pipes instead
of 1 and clocked higher), not to mention hardware tcl (doesn't matter for
glxgears, though).
Apart from the things mentioned above, I don't think there is really that much
more performance to gain for that chip.
Comment 7 Erik Andren 2006-05-10 06:27:29 UTC 
As Roland stated, performance is what to be expected for a R6 chipset.

> As Roland stated, performance is what to be expected for a R6 chipset. 

I've also got an Radeon 7000 (aka Radeon LY M6) in my Sony Z1RMP notebook and I get 568 FPS with glxgears (default window size) using the opensource radeon driver under openSUSE 10.2.

My config is:

  Driver       "radeon"
  Identifier   "Device[0]"

Not that much, but I guess much more FPS won't be possible with this gfx card. Please correct me if I'm wrong! *g*

HTH,
Jochen
Comment 9 Jochen 2007-02-15 14:03:01 UTC 
Sorry, 

I forgot to mention that Xorg's version is 7.2 and I'm using a color depth of 16 bits at a resolution of 1400x1050. You can't use a higher color depth with this resolution for the gfx card has only 16 MB of RAM installed while having DRI available (see [1]).

Keep on rockin'
