The IW engine is a game engine developed by Infinity Ward for the Call of Duty series and has recently become the main engine for the James Bond video games. The engine itself is proprietary with inclusion of GtkRadiant by id Software. It has been used by Infinity Ward, Treyarch, Raven Software, and Sledgehammer Games.
The engine was first used for Call of Duty 2 in 2005 under a proprietary license of id Tech 3 created by id Software in 1999, as at this time, the engine was a heavily modified version of the Quake III engine. The engine did not have an official name until IGN was told at the E3 2009 by the studio that Call of Duty: Modern Warfare 2 would run on the "IW 4.0 engine".[1]
Call of Duty 4: Modern Warfare was released using version 3.0 of the engine. Treyarch began using an enhanced version of the IW 3.0 engine for Call of Duty: World at War.[2] Treyarch, however, then modified the engine for their James Bond title, Quantum of Solace.[3]
Call of Duty: Modern Warfare 2 was released using the IW 4.0 engine, the only game to do so. The IW 4.0 engine featured texture streaming technology to create much higher environmental detail. Treyarch then further modified the IW 3.0 engine for Call of Duty: Black Ops. The engine was also modified by Eurocom in a different way for the GoldenEye remake. Call of Duty: Modern Warfare 3 utilizes the IW 5.0 engine, the fifth iteration of the engine and an improved version of the IW 4.0 engine.[4] Improvements on the engine allow better streaming technology which allows larger regions for the game while running at a minimum of 60 frames per second and improvements to the audio of the engine have also been made.
