Id Tech 6

id Tech 6 is a multiplatform game engine developed by id Software. It is the successor to id Tech 5 and was first used to create the 2016 video game Doom. Internally, the development team also used the codename id Tech 666 to refer to the engine. The PC version of the engine is based on the Vulkan API and the OpenGL API. John Carmack started talking about his vision regarding the engine that would succeed id Tech 5 several years before the latter debuted in Rage, but following his departure from id Software in 2014, Tiago Sousa was hired to replace him as the lead renderer programmer at the company. On June 24, 2009, id Software was acquired by ZeniMax Media. It was later announced in 2010 that id Software's technology would be available only to other companies also belonging to ZeniMax Media. It was followed up by id Tech 7.
