ATI's OpenGL SDK

Someone gives this link in the OpenGL-GameDev email list.
I think I didn’t see it announced at www.opengl.org.
The SDK (http://www.ati.com/developer/sdk/radeonsdk/Gl_sdk.zip) contains an interesting document titled: “Radeon 9500/9600/9700/9800 OpenGL Programming and Optimization Guide”

There are other resources in the page.

Hope you find it interesting.
