What is Mouse Latency?

Mouse latency (or input lag) is the time it takes for your physical mouse click to be registered by your computer and the application (like a game). High latency can lead to delays and is a critical issue for competitive gamers and professionals who need precise timing.

What is a Good Mouse Latency?

Understanding your latency score is important. Here’s a general guide:

How to Reduce Mouse Input Lag?

If your score seems high, here are a few simple steps you can take to fix mouse delay:

  1. Use a Wired Mouse: A wired connection is almost always faster than wireless (Bluetooth or 2.4Ghz).
  2. Update Drivers: Ensure your mouse drivers and graphics drivers are up to date.
  3. Change USB Port: Try plugging your mouse into a different USB port, preferably one directly on the motherboard (at the back of your PC).
  4. Close Background Apps: High CPU usage can cause input delays. Close unnecessary browser tabs and applications.

Wired vs. Wireless Mouse: Latency Comparison

Historically, wired mice have always had lower latency. However, modern wireless technology (like Logitech's Lightspeed or Razer's HyperSpeed) has closed the gap significantly, offering latencies that are practically identical to their wired counterparts.

However, cheaper Bluetooth mice often have high and variable latency, which is not ideal for gaming. This tool can help you test if your wireless mouse is performing well.

Frequently Asked Questions

Accuracy depends on your device and browser performance, but it provides a good estimate of input delay by measuring the time between the 'mousedown' event and the 'click' event using the browser's high-resolution timer (`performance.now()`).

Yes. Wired or wireless, any mouse can be tested as long as your browser registers the input events.

No, this is a fully browser-based tool.
