Khronos Group ha annunciato il rilascio delle specifiche OpenGL 4.2. Le specifiche complete sono disponibili a questa pagina.

New functionality in the OpenGL 4.2 specification includes:
  • enabling shaders with atomic counters and load/store/atomic read-modify-write operations to a single level of a texture.  These capabilities can be combined, for example, to maintain a counter at each pixel in a buffer object for single-rendering-pass order-independent transparency;
  • capturing GPU-tessellated geometry and drawing multiple instances of the result of a transform feedback to enable complex objects to be efficiently repositioned and replicated;
  • modifying an arbitrary subset of a compressed texture, without having to re-download the whole texture to the GPU for significant performance improvements;
  • packing multiple 8 and 16 bit values into a single 32-bit value for efficient shader processing with significantly reduced  memory storage and bandwidth, especially useful when transferring data between shader stages.
