Explicit thread control and closer to the metal, but OpenGL not dead yet. Khronos has released Vulkan 1.0, the next generation open graphics API, and a Vulkan SDK for Windows and Linux is now available from LunarG.
Khronos is an industry consortium which creates open graphics standards, including OpenGL and WebGL. Vulkan was announced in March 2015 and represents the next generation after OpenGL, though Khronos is keen to emphasise that OpenGL, and the cut-down OpenGL ES designed for mobile and embedded use, remain in active development.
