PrBoom

PrBoom, short for Proff Boom, is a source port for Windows and Linux based on LxDoom and MBF. It was first started and developed by Florian "Proff" Schulze and is currently maintained by Colin "cph" Phipps.

PrBoom's flagship feature is its accurate compatibility with vanilla Doom recorded demos. Currently it plays back almost every vanilla demo flawlessly.

In addition to the official PrBoom versions Andrey Budko has further developed PrBoom on his own and released his work as an unofficial version of it. His version features, among other things, an uncapped framerate and a togglable walkcam view for demo playbacks.
