OpenGL is a graphics standard released in mid 1992. OpenGL is simpler than the popular Vulkan API, but consequently will on average perform slightly worse than Vulkan. The latest version of OpenGL is version 4.6, released in 2017. Since version 4.6, active development of OpenGL has been dropped in favor of Vulkan.


OpenGL is an API standard, and not a an actual library in it of itself. OpenGL was designed for most if not all of its API to be hardware accelerated, but OpenGL rendering can also be implemented entirely on the CPU. The OpenGL core API is smaller than Vulkan, but OpenGL also as plenty of extensions that can add more functionality.
