Summary
Headless clients on an Arma 3 server are additional instances of the game that run without a graphical interface, focusing solely on processing AI and other simulation tasks. These headless clients offload computational work from the server's central instance, improving performance and reducing player latency. By distributing the workload across headless clients, Arma 3 servers can handle larger-scale battles and complex scenarios more efficiently, enhancing the overall gameplay experience.
