• Lag Switch (Windows, macOS, Linux): A simple, open-source tool that allows you to configure a delay.
• Network Delay (Windows): A free tool that allows you to introduce a delay in your network connection.
• tc (Traffic Control) (Linux, macOS): A command-line tool for configuring network traffic control, including adding delays.

• Network condition simulators: clumsy, Clumsy, Network Link Conditioner (macOS), dummynet.
• Learn game netcode – Read Source Engine’s lag compensation articles, GDC talks on rollback netcode.
• Practice ethical hacking – Use lab environments (e.g., your own game server + client).

• Virtual lag switches do work in some peer-to-peer or poorly secured games, but modern anti-cheat detects irregular timing patterns.
• Result = permanent ban, lost progress, and public shaming (Overwatch, CoD, R6 Siege, Valorant have banned thousands for network manipulation).
• Worse: Some “free lag switch” downloads contain keyloggers or crypto miners.
