OpenGL-Next has been under development for about one year as an API designed to better compete with Microsoft Direct3D 12, AMD Mantle, and Apple Metal. While it could take years for the next-gen API to be widely adopted, it's going to be shown off at the Game Developers' Conference in March.
One of the GDC sessions is entitled glNext: The Future of High Performance Graphics. Currently the session is listed as presented by Valve while previously it said presented by Khronos Group. The session will also have developers from EA, Epic Games, Oxide Games, and Unity.
They will be showing off drivers and hardware running glNext. From the schedule, "Join us for the unveiling of Khronos' glNext initiative, the upcoming cross-platform graphics API designed for modern programming techniques and processors. glNext will be the singular choice for developers who demand peak performance in their applications. We will present a technical breakdown of the API, advanced techniques and live demos of real-world applications running on glNext drivers and hardware."
Put 5 March on the calendars!
