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 has arguably been distinct from the id Tech 3 engine on which it is based since Call of Duty 2 in 2005. The engine's name was not publicized 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". Development of the engine and the COD games has balanced maintenance of 60 frames per second with implementing advanced graphical features.
Call of Duty 4: Modern Warfare was released using version 3.0 of the engine. This game included features such as bullet penetration, improved AI, lighting engine upgrades, particle system enhancements and many more improvements. Treyarch began using an enhanced version of the IW 3.0 engine for Call of Duty: World at War.Improvements were made to the physics model and dismemberment was added. Environments also featured more destructibility and could be set alight using the flamethrower. The flamethrower featured propagating fire and it was able to burn skin and clothes realistically. Treyarch, however, then modified the engine for their James Bond title, Quantum of Solace.
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 without sacrificing performance. Call of Duty: Black Ops was not based on IW 4.0; rather, Treyarch further enhanced the version of IW 3.0 they had used in their previous game. This version of the engine also featured streaming technology, lighting enhancements, and support for 3-D imaging. Call of Duty: Modern Warfare 3 utilizes an improved version of the IW 4.0 engine. 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. Further improvements to the audio and lighting engines have been made in this version.
Call of Duty: Black Ops II was developed using a further iteration of the IW engine. Texture blending has been improved due to a new technology called "reveal mapping" which compares tones between two textures and then blends them together. Also, there have been upgrades to the lighting engine which include HDR lighting, bounce lighting, self-shadowing, intersecting shadows and various other improvements. Call of Duty: Black Ops II takes advantage of DirectX 11 video cards on the PC version of the game. The "zombie" mode has been moved to the multiplayer portion of the engine which will allow for much more variety within this part of the game. Black Ops II was released on the 13th November 2012.
