Input lag in networked arcade game machines can significantly impact gameplay, causing frustration for players. To minimize this issue, several effective methods are commonly employed:

1. Optimized Network Infrastructure: Using high-quality routers and switches with low latency ensures stable connections. Prioritizing gaming traffic through QoS (Quality of Service) settings can also reduce delays.

2. Frame Synchronization: Techniques like VSync or adaptive sync help align frame rates between the game and display, reducing stuttering and input lag.

3. Efficient Input Polling: Increasing the polling rate of input devices (e.g., joysticks, buttons) ensures faster response times, minimizing delay between player actions and on-screen reactions.

4. Local Processing: Offloading some computations to the local machine instead of relying entirely on the network can reduce dependency on latency-prone connections.

5. Low-Latency Displays: Using monitors or screens with high refresh rates and minimal response times further enhances responsiveness.

By implementing these strategies, arcade operators can deliver a seamless gaming experience, keeping players engaged and satisfied.
