Kompletní Release notes - Catalyst™ Software Suite Version 9.8 Release NotesNew 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:Performance Improvements
- 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 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
