Hi,
for posterity and the future frustrated, here is what had to be done
make the FirePro believe it can do OpenGL.
Specs again:
Dell Precision M6600
AMD (ATI) FirePro M8900 (FireGL) Mobility Pro Graphics
Driver version: 2011/05/31 8.851.0.0
Windows 7 64-bit
Grep the OSG source code for "Radeon" and everywhere add "FirePro" for
the existing workarounds. They have the same Pro-ness.
Short circuit State::computeVertexBufferObjectSupported() to return
false no matter what.
Make the databasepager use display lists:
pager->setDrawablePolicy(osgDB::DatabasePager::USE_DISPLAY_LISTS);
After all this, OSG at least does not crash, but an annoying +-1s pause
was occurring every now and then. This appears to be happening in other
OpenGL apps too.
To get rid of the pauses we had to disable all eye-candy on Windows 7,
i.e. switch to the "classic" theme.
I've now wasted enough time on this.
If you got this far, let it be a reminder to spend a bit more and get
the NVidia GeForce/Quadro next time.

PS. Wish I could find an AMD support email address to copy this too, but
they're hiding behind web forms with lots of "required fields". Bah.

Hi Luc,
thanks for the feedback. I'm going to try disable VBO wherever possible
and see what happens. I'll probably have to make a visitor for all other
loaded objects or somehow convince OSG that the ATI does not support VBO.
I've been spared the ATI madness till now, so I'll check the list for
older VBO workarounds too.
It's sad that ATI/AMD misuses their advantage of being the underdog [1]
to keep churning out crap OpenGL support.

[1] People like competition and always seem to give ATI/AMD another
chance, only to be disappointed again.

I work on a Dell M6400 with a FirePro M7740 on Windows 7 64-bit.
Same issue.
Hours of installation/desinstallation of different drivers did nothing.
The only workaround I've found is to disable VBO :
pager->setDrawablePolicy(osgDB::DatabasePager::USE_DISPLAY_LISTS);
There is also an Env setting to do that I think.
It put an end to Geometric nightmare and random crashes.
I really don't know what's pro in Ati FirePro...

Hi all,
we've got users with shiny new Dell Precision M6600 laptops with the
FirePro M8900 ATI chips on Windows 7 64-bit. Terrain databases that work
perfectly well almost everywhere produce artistic but not quite pleasing
results in osgviewer, see attached.
Any ideas on how to work around ATI's OpenGL uselessness? We've already
suggested buying NVidia cards :/
Help on installing other driver versions, other than those blessed by
Dell with AMD shrugging their shoulders [1], would also be welcome.
cheers
