Here’s a fun way to make a lag switch, it allows you to “cheat” on online games by disrupting the Rx (receiving) channel while the Tx (sending) channels keep working. The other users get a lag while you shoot them basically.
Great idea, but if you need to cheat that bad, you should just keep practicing more instead.
By attaching a physical device (called a lag switch) to a standard Ethernet cable, a player is able to disrupt updates/communication from the server with the intent of tricking the game server into continuing to accept client-side updates (which remain unimpeded). Since the client game-player is impeding the reception of information download, on the client game-player’s side the opponents will slow down or stop moving, allowing the client game-player to more easily shoot them, block them, out-race them, etc. From the other players’ perspectives, the person using the lag switch may appear to be teleporting, invincible, having delayed animations or fast-forwarded game play, or the player may simply find themselves losing to an invisible opponent.
