"ATI Catalyst drivers versions 10.5 & 10.6 are bugged & cause graphical anomalies; revert to 10.4 or try a workaround (at your own risk)
This is a problem with the current ATI drivers. The original thead about it is in Technical Support: http://www.quakelive.com/forum/showthread.php?t=50581

Update, June 19th: A workaround has been discovered. This is a completely unofficial solution and if you are not an advanced computer user, you are highly recommended to roll back to version 10.4 instead of trying the workaround--do so at your own risk.

Since Catalyst 10.5 and now amazingly 10.6 (you would think they'd fix it in the next release.. sigh) are currently bugged with most if not ALL opengl games including QL, we must urge you to stay with Catalyst version 10.4.

it is the latest release that does not effect opengl support and cause visual errors (white color models etc).

The issue has been brought to the devteam's attention since 10.5 but as it's an actual ATI issue effecting most opengl games, there is no magical fix the QL Devteam can do. We must sadly sit and wait for good ol' ATI to fix their horrible driver mess."


The second one is the main fix that most will need.

If you don't want to mess around with the copy of atioglxx.dll in the System32 or SysWOW64 directory just paste the file into the folder your broken application is installed in. It fixed Anachronox for me :]

*sigh* I thought ATI was past their crappy OGL support...

Eh, it's not that big of a deal. They'll fix it. Besides, DirectX is better anyway.
