The rest of us would love to know how you've pulled that off. Quake 3 and Return to Castle Wolfenstein crash instantly on every AMD system I have, and many others in various threads have confirmed the issue.
All I can figure (and this is a blind guess) is there's a bug in AMD's driver installer that causes it to fail overwriting atioglxx.dll when updating. The old DLL stays in place, no issues with OpenGL games.
Edit: Here's a log dump from Return to Castle Wolfenstein. The log file simply cuts off in the middle of loading OpenGL extensions (there are too many for the engine to handle). An extension limit would fix things right up.
I just found something while researching this.
Do you have a file in your C:\Windows called atiogl.xml? Here is what I have and its contents.
Code:
<!-- Return To Castle Wolfenstein -->
<rtcw>
<OpenGLCaps>0x00008000</OpenGLCaps>
<OpenGLCapsEx>0x00000000</OpenGLCapsEx>
</rtcw>
<!-- Quake 3 -->
<quake3>
<OpenGLCaps>0x00008000</OpenGLCaps>
<OpenGLCapsEx>0x00000020</OpenGLCapsEx>
<OpenGLCapsEx2>0x00020000</OpenGLCapsEx2>
</quake3>
Here is a screenshot of my gfx info.
