The program allows a server to predict the movement of an object based on its present speed and trajectory. In other words, the server does not need to receive information from the client for every second of a player's movement. The server can fill in some of the gaps created by lag and allow the player to move at a normal rate. This is a great aid for the majority of Quake players that connect to the internet through a 33.6k or slower modem. With QW, clans can now create their own custom characters and use these skins in multi-player games.
Players can select any of the hundreds of available skins to wear during a game.
While this may not seem like a great tactical advancement, it certainly does allow clans a great way to showcase their creativity. These commands are different than the hundreds for regular Quake, and perform different function. A complete list of commands can be found at QuakeWorld Central . Pushlatency informs your computer how much it should compensate for lag. The command should be entered into the console with an appropriate parameter.
