Steps for Fixing Windows 10 Mouse Lag

This problem affects all Windows 10 editions, 32-bit and 64-bit.

  1. Firstly, if it’s a wireless mouse, get fresh batteries. Unplug your wired Mouse from your computer and replug it. In case it doesn’t work, go for a spare mouse or a different port on your desktop.

NOTE: Unplugging and replugging your Mouse may sometimes restart the driver and get it functioning again.

Unplugging and replugging
  1. Get Rid of Dust – If your Mouse lags intermittently, dirt may be obscuring the IR sensor beneath your Mouse. A sluggish mouse scrolling indicates a dirty scroll wheel. Cleaning your Mouse is one of the first steps in solving odd mouse scrolling.
  2. Try it on another machine. If you don’t have another PC, try an iPad, PS4, or Xbox. You know the problem is with your computer, not the Mouse, if it works well on another device but lags on Windows 10.
  3. Check another USB port for the Mouse. If you’re using a USB 3.0 port on your processor, shift to a USB 2.0 port. To fix a non-working USB port, you must first troubleshoot the USB port itself.
  1. Install the brand-new mouse operator. There are two methods. Open Device Manager, locate your Mouse and let Microsoft download the latest driver. The easiest way is to go to the operator’s website and download the driver for your Mouse.
Open Device Manager

  1. Examine your mouse speed and sensitivity or DPI. A recent Windows Update may have reverted your mouse settings to default. Default settings may cause mouse latency if you’re used to modifying settings. Touchpad delay and mouse acceleration may also create erratic mouse movements. In this situation, disabling mouse acceleration and updating the touchpad to “No delay” works well.

NOTE: If you think the latest Update is causing your mouse latency in Windows, remove it and reinstall it.

  1. Some users say Cortana causes mouse latency. Turning off Cortana is a brilliant first step. If this works, you should troubleshoot Cortana to figure out what’s wrong.
  2. High-definition audio devices have created mouse latency problems for specific users. Visit the Device Manager. Please turn off the High Definition Audio Device (it is regardless of sound card manufacturer). Reboot your computer before confirming that this fix fixed your mouse problems.

  2. Windows Power Saving Mode may also influence mouse behavior. If your laptop is disconnected, Windows may try to switch off the USB port to conserve battery. Turn off the Power Saving mode to check if that helps.
