ATI Catalyst Drivers 9.8 XP 64

New Features:

* OpenGLâ„¢ 3.1 extension support

OpenGLâ„¢ 3.1 extension support:

* Support for OpenGL Shading Language 1.30 and 1.40
* Instanced rendering with a per-instance counter accessible to vertex shaders (GLARB draw instanced)
* Data copying between buffer objects (GL EXT copy buffer)
* Primitive restart (NV primitive restart). Because client enable/disable no longer exists in OpenGL 3.1, the PRIMITIVE RESTART state has become server state, unlike the NV extension where it is client state. As a result, the numeric values assigned to PRIMITIVE RESTART and PRIMITIVE RESTART INDEX differ from the NV versions of those tokens
* At least 16 texture image units must be accessible to vertex shaders, in addition to the 16 already guaranteed to be accessible to fragment shaders
* Texture buffer objects (GL ARB texture buffer object)
* Rectangular textures (GL ARB texture rectangle)
* Uniform buffer objects (GL ARB uniform buffer object)
* SNORM texture component formats
