OpenGL 3.1 Support
- 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.
