There is a bug that affects at least some AIW 9xxx cards using OpengL in graphic applications and games.
Rage3D thread
Here's what I did to "fix" the OpenGL bug:
Replaced the ATI opengl driver "atioglxx.dll" dated 9-30 with the Cat 3.8 version dated 9-12.
*rename the atioglxx.dll file in "C:\WINDOWS\system32" to atioglxx.dllOLD
*Find the driver in "C:\ATI\SUPPORT\wxp-w2k-catalyst-7-94-030917m-011434c\Driver\2KXP_INF\B_11252\atioglxx.dl_" (default Cat 3.8 installation folders)
*Use the expand command to decompress (paste this into the "run" command box if you've used the default folders "C:\WINDOWS\system32\expand.exe C:\ATI\SUPPORT\wxp-w2k-catalyst-7-94-030917m-011434c\Driver\2KXP_INF\B_11252\atioglxx.dl_ C:\WINDOWS\system32\atioglxx.dll"
Works fine now. I'm not sure which cards are affected, but my AIW 9700 pro definately is.
