Hi there, I just sent my first test app to a friend of mine, having a voodoo3. But he get''s a frame rate of 1 or 2 per second... How can I achieve hardware acceleration on Voodoo cards.... I always thought that there are already good gl drivers.... Thanks in advance

Yeah, I can get OGL to run well on Voodoo1s and -2s, but not all -3s. Some work, some don''t...

You prolly know this, but I''ll say it anyhow: try getting the newest drivers.
Also make sure you work in 16bit -that''s the only thing that voodoo likes

Well I always had Nvidia products so never was able to test it on 3dfx cards...... So there are new drives that accelerate OpenGL ? I read somewhere, that I have to avoid certain functions and that I have to load certain dlls myslelf. But I have no idea at all.

i have a voodoo3, and i used to have VERY poor OpenGL fps. all you need to do is update to the newest drivers, you will be amazed at the difference it makes.

Just one quick idea. I''ve seen in halflife an option tio use glminidriver. Perhaps that when using default opengl32.dll it does not enable hardware acceleration.Put an option in the beggining to select the opengl dll.

Go to 3dfx.com and get the latest ICD driver for the card (dont confuse ICD with miniGL...).

OpenGL should use 3dfx driver automatically (either in Fullscreen and Windowed mode) without .dll rename. In other
words the app will search for OpenGL32.dll but it will use the 3dfx(...?).dll.

To be sure that you are using 3dfx driver you should see 3dfx logo when you create GL render context in fullscreen mode.

To develop OpenGL apps you may use GLSetup...

NOTE : Voodoo3 is lightning fast under OpenGL !
