In traditional NVIDIA fashion, they already have beta OpenGL 4.3 proprietary drivers (Linux support included) at. New functionality provided by the OpenGL 4.3 specification includes: compute shaders leveraging GPU parallelism within the context of the graphics pipeline, shader storage buffer objects, texture parameter queries, high-quality ETC2/EAC texture compression as a standard feature, debug capabilities to receive debugging messages during application development, texture views for interpreting textures in different ways without data replication, increased memory security, and a multi-application robustness extension. It's been twenty years since the release of the original OpenGL specification and this royalty-free multi-platform graphics specification keeps moving forward.
Just as I reported last week would happen at SIGGRAPH and in late May first talked about OpenGL ES 3.0, today at the first day of SIGGRAPH LA 2012 the Khronos Group announced the release of the OpenGL 4.3 and OpenGL ES 3.0 graphics API specifications.
