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
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 theě 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
