ATI Catalyst 9.4: One New OpenGL Extension



ATI Catalyst Graphics Drivers

OpenGL 3.0



Here is the list of OpenGL extensions exposed by the graphics driver Catalyst 9.4 for a Radeon HD 4850 under Windows XP SP3 32-bit.

Compared to Catalyst 9.3, Catalyst 9.4 introduces one new OpenGL extension:

  • GL_EXT_copy_buffer: not really sure, but this extension seems to be used to copy data between buffer objects. We have to wait an official extension description for that.

Update (2009.04.11)
GL_EXT_copy_buffer is actually the same extension than GL_ARB_copy_buffer. Here is the official description:

This extension provides a mechanism to do an accelerated copy from one buffer object to another. This may be useful to load buffer objects in a “loading thread” while minimizing cost and synchronization effort in the “rendering thread.”
