TV/Capture functionality is qualified to function with Snapstream’s
BeyondTV 4.6 for Windows Vista. Other third party solutions (such as
Arcsoft’s Total Media 3) may support TV/Capture with the ATI All-in-
Wonder™, but these applications have not been fully tested by AMD.

New Features:

This section provides information on new features found in this release of the Radeon™
Display Driver. These include the following:

OpenGL™ 3.1 extension support

This release of ATI Catalyst™ provides OpenGL™ 3.1 extension support. The
following is a list of OpenGL™ 3.1 features and extensions added in Catalyst 9.8:

* Support for OpenGL Shading Language 1.30 and 1.40
* Instanced rendering with a per-instance counter accessible to vertex shaders (GL
ARB 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
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
