- Try to determine which 3dfx card we are using
- Use GL_CLAMP for 3dfx instead, fixes dynamic lights/skyboxes/etc. (GL_CLAMP_TO_EDGE becomes GL_REPEAT on older 3dfx drivers)
- Support for 3dfx gamma control and overbrights restored
- Indexed w/ alpha color is now forced GL_RGBA on Voodoo Graphics (v1)
- attempt at silencing the 3dfx splash
