The war rages on with the open source OpenGL and Microsoft’s DirectX. OpenGL is working on version 4.0 to bring its features up to par with the newest DirectX 11. The battle has been going on since the start of DirectX, with both sides having advantages.
OpenGL 4.0 adds more support for using a graphics processing unit (GPU) for other computing chores and for tesselation, which subdivides a region on a graphics object into many smaller patches for more detailed imagery. The technology got its start as a graphics library at pioneering Silicon Graphics but has grown into a standard that works on many different computer systems and overseen by the Khronos Group.
