In 1999, id Software released Quake III Arena, a multiplayer FPS shooter. It differed from previous games in the absence of a single-player story mode and in the presence of only a multiplayer part. At the time, many were amazed at how quickly this game rendered graphics, and no one understood how the developers managed to achieve such speed.
1333 FPS – the limit is in the engine, but it can also be removed
After publishing the source code of the game, it was discovered that it contains an unknown algorithm called Fast Inverse Square Root. Former Microsoft software developer David Plummer released a video in which he told the story of this strange algorithm, explained how it works, and also told a little about its possible creator.
David William Plummer is a Canadian-American computer programmer and entrepreneur. He is best known for building the Windows Task Manager, Space Cadet Pinball ports for Windows NT, ZIP support for Windows, HyperCache for the Amiga, and many other software products. He also holds 6 software development patents.
