Rockstar Advanced Game Engine

Rockstar Advanced Game Engine (RAGE) is a game engine developed by the RAGE Technology Group at Rockstar San Diego with contributions by other Rockstar studios. The engine has been used on several different platforms such as Microsoft Windows, Nintendo Wii, PlayStation 3, PlayStation 4, Xbox 360 and the Xbox One. RAGE initially evolved from the Angel Game Engine originally developed by Angel Studios for Midtown Madness and later the sixth generation console era versions of the Midnight Club series and other Rockstar San Diego games.

Rockstar has integrated a few third party middleware components into RAGE like the proprietary Euphoria character animation engine and the open-source Bullet physics engine. Prior to RAGE, Rockstar mostly used Criterion Games' RenderWare engine to develop various game titles, including the PlayStation 2, Xbox, and Microsoft Windows installments of the Grand Theft Auto franchise. Since the release of Max Payne 3, the engine supports DirectX 11 and stereoscopic 3D rendering on the PC platform.
