Everyone seems to be going bananas over GL3, does it bring any noticeable change?
I'm just a hobbyist OpenGL developer who can't wait playing with it . It has some nice abilities like new texture types and arrays of textures which are quite nice from developing point of view. Besides that, if AMD has OpenGL 3.0 support, they MUST implement all functionality that is included in OpenGL 3.0. Problem with OpenGL 2.1 was that some functionality which you would like to use is only available in extensions. The vendors (AMD, nVidia, Intel, etc.) are not forced to implement the extensions. For AMD this has often meant: they were just not implemented.
