id Tech 5 is the latest proprietary game engine being developed by id Software, currently still being actively upgraded, and follows its predecessors, id Tech 1, 2, 3 and 4. It is a major advancement over id Tech 4. The engine was first demonstrated at the WWDC 2007 by John D. Carmack on an eight-core computer; however, the demo used only a single core with single-threaded OpenGL implementation running on a 512 MB 7000 class Quadro video card. id Tech 5 was first used in the video game Rage, and the upcoming Doom 4 has also been announced to make use of it.
