Enemy Territory: QUAKE Wars (ETQW) is the latest game using the DOOM 3 engine, or as id Software rechristened it, the id Tech 4 engine. Although the normal map, stencil shadow heritage is still present many things have changed both under the hood and in end-user effects and you could arguably call this version 1.5 of the engine.
Last year we published a small interview with Splash Damage's Technical Director, Arnout van Meer, touching on many different subjects. Now that the game is in stores it's time to delve a little deeper into the new features on the improved DOOM 3 engine that powers QUAKE Wars and see how it compares to other current and upcoming engines. Throughout this article you'll find quotes from Arnout as well as Mike Armstrong, Senior Graphics Programmer at Splash Damage, providing some of the reasoning behind a few technical aspects of the engine.
