Reducing input polling latency in arcade controls is crucial for competitive gaming and smooth gameplay. Here are the most effective methods to achieve lower latency:

1. Use High-Quality Hardware: Opt for arcade sticks and buttons with low input delay, such as those with mechanical switches or optical sensors.

2. Optimize Polling Rate: Ensure your controller or interface supports a high polling rate (e.g., 1000Hz) to minimize delay between input and response.

3. Direct Input Connection: Avoid USB hubs or extensions; connect controls directly to the PC or console to reduce signal interference.

4. Firmware Updates: Keep your arcade control firmware updated to benefit from latency-reducing optimizations.

5. Software Tweaks: Disable unnecessary background processes and use gaming modes in operating systems to prioritize input responsiveness.

By implementing these strategies, you can significantly reduce input polling latency and enhance your arcade gaming experience.
