wierd OpenGL problem...

I’m running an original 233mhz iMac, and I have the 8MB GameWizard Voodoo2 card installed. It used to work great for playing Quake 2, Quake 3, and other OpenGL based games. After installing the MacOS 9.2.2 update it installed a newer version of OpenGL (1.2.4) and now when I open any OpenGL based game all textures appear completely white. The card still works fine for 3Dfx Glide based games like Unreal, Unreal Tournament, Deus Ex, and Quake 1. I have the 3Dfx OpenGL Renderer version 1.0b11 installed in my extensions folder and the GameWizard RAVE and GameWizard GLIDE extensions all installed. Anyone know how to fix this? I want my OpenGL games to work!
