t's difficult to think of a single category of application that's driven the pace of desktop hardware development further and faster than first-person shooters. Maximum PC examined the evolution of FPS engines, looking back at the key technologies that brought games from the early sprite-based days of Doom to the fully 3D-rendered African Savannah as rendered by Far Cry 2's Dunia engine. It's truly amazing how far the state of the art has moved in the last 16 years.
