How to fix mouse lag on Windows or Mac PC

Almost everyone who uses a computer does so with a mouse and keyboard, but there are times when the first device does not work correctly. Mouse lag occurs when the cursor moves slowly, resulting in delayed response and actions, and feels unintuitive. Lag stops productivity and is very annoying to work with.

Mouse lag can be the result of many problems, but there are clear solutions for them. Continue reading to know all the details if you want to know how to solve the problem.

Fix mouse lag in Windows 11

Mouse lag in Windows 11 is not difficult to fix. The most common causes are broken drivers or Bluetooth mice that are finicky. However, it is not always the fault of the device.

Update mouse drivers

Mouse drivers ensure that your mouse works properly. If they are not updated, problems such as delays may occur. Follow these instructions to renew them.

1. Right click on the Start button.
   
2. Choose “Device Manager.”
   
3. Find “Mice and other pointing devices” and double-click it.
   
4. Click on the “Driver” tab.
   
5. Then click “Update Driver”.
   
6. Select “Search for drivers automatically.”
   
7. If there are new ones, wait for them to install and restart your computer.

However, this method may not work. You may need to download drivers created specifically for your mouse. Find your drivers and follow these steps.

1. Use your browser and search for your mouse model.
   
2. Go to the manufacturer’s website.
   
3. Download the correct driver.
   
4. Follow the installation instructions.

If all goes well, the mouse lag will disappear.

Enable or disable the Windows idle scrolling option

This setting allows users to automatically scroll in inactive windows by simply hovering over the page. But it may introduce mouse lag depending on the computer. Having it on sometimes helps, but others find turning it off is key to fixing mouse lag. Learn how to do it below.

1. Right-click the Start button and select “Settings.”
   
2. Go to “Bluetooth & devices”.
   
3. Scroll down and select “Mouse.”
   
4. Enable or disable “Scroll inactive windows when hovering over them” several times.
   
5. Test and see if the lag still persists.

Fix mouse lag in games

While many of the solutions we will mention also fix mouse lag when playing video games, here are a few steps that generally help a lot. Turning off the Game Bar or disabling mouse acceleration when gaming can make everything run smoother. Doing so conserves system resources.

To turn off the Game Bar, try these instructions.

1. Click the Start button and choose “Settings.”
   
2. Go to the “Games” section.
   
3. Turn off the option to open the Xbox Game Bar.
   
4. Go back to the Settings menu and go to “Applications.”
   
5. Find the “Xbox Game Bar” list and click the 3 dots.
   
6. Select “Advanced Options.”
   
7. Click “Never” in the drop-down menu labeled “Background App Permissions.”
   
8. Scroll down and select “Finish.”
   

The Game Bar is useful for some gamers, but it’s not always the best feature for staying active. Read the following steps to disable mouse acceleration.

1. Open the Start menu and click “Settings.”
   
2. Go to “Bluetooth & devices”.
   
3. Select “Mouse” from the list.
   
4. Open “Additional mouse settings”.
   
5. Uncheck “Improve pointer precision”.
   
6. Apply the settings and click “OK.”
   

Mouse acceleration may conflict with game settings or third-party mouse drivers. By disabling it, you can eliminate an unnecessary cog in the gaming “machine.”

Fix mouse lag in Windows 10

While the fixes for Windows 11 can also be applied to Windows 10 with some slight differences, we will still cover some new fixes for Windows 10.

Modify the PalmCheck threshold

This is a Windows 10-only setting that sometimes causes trackpad lag. Only found on laptops or if you are using an external trackpad.

1. Right click on the Start menu.
   
2. Go to the Settings menu.
   
3. Go to “Devices.”
   
4. Click “Touchpad” and “Settings” under “Synaptics Touchpad.”
   
5. Move the slider under “PalmCheck” to the left as far as it will go.

If it doesn’t eliminate mouse lag, you’ll need to try something else.

Disable High Definition Audio from NVIDIA or Realtek HD Audio Manager

NVIDIA’s High Definition Audio may cause problems for some users, and the same can be said for Realtek HD Audio Manager. Some computers will not have the first option, especially if they have an AMD CPU.

1. Right click anywhere on the taskbar.
   
2. Open Task Manager.
   
3. Click “Details.”
   
4. Scroll down, find one of these two processes and click on the application.
   
5. Select “End Task.”
   

If your mouse is still lagging, it’s probably not the fault of the audio process. It would be best if you tried looking at the mouse.

Check the mouse

These tips work on all devices and operating systems. While the exact steps may vary, it is best to test them in detail.

Users who prefer a Bluetooth mouse may experience delays if the mouse is too far from the computer or if there are objects causing interference. The only solution for this is to get closer and remove the obstacles so that the signal can be transmitted to the computer without being blocked.

If your mouse is designed for USB 2.0, do not connect it to a USB 3.0 port. It can cause problems such as delays. Save the 3.0 port for newer devices, as they will benefit the most from the update.

All devices eventually fail, and sometimes it’s time to buy a new mouse. While your current one may have served you well over the years, you want to play games or use your computer without mouse lag. Consider purchasing a higher-end model that will last longer.

Fix mouse lag in Windows 7

Windows 7 remains surprisingly prevalent in recent years due to its stability. However, mouse issues can still occur even on this legacy operating system.

Disable fast startup

Fast boot is also sometimes known as fastboot or quickboot, and is an option designed to speed up boot times. But there are times when it causes more harm than good. Disabling it should eliminate some performance issues, such as mouse lag or freezing.

Windows 7 users must enter the BIOS to disable fast startup. Because every computer is different, follow the exact steps to access the BIOS.

When using the BIOS menu, be careful not to modify settings that you are unsure of. You may cause problems this way and need to enter the BIOS again.

1. Restart your computer.
   
2. Enter the BIOS or you can access the BIOS by clicking “Control Panel” in the Start menu.
   
3. Look for the Quick Startup option.
   
4. Click the “Disable all” button.
   
5. Test your mouse after exiting the BIOS menu and letting the computer boot.

Move your wireless router and other devices

Wireless mice transmit signals and interference can occur if there are too many wireless devices in a room. In these cases, you can move your router to a different location. The wireless mouse should have no objects or other signals between it and the dongle or computer.

Likewise, avoid having radios or other signals active when using a wireless mouse. Interference is very possible but avoidable.

Fix mouse lag on a Mac

Macs are generally reliable computers, but mouse lags can also occur. Check out the tips below to learn how to get rid of it.

Turn Bluetooth on and off again

Bluetooth problems can be resolved by turning Bluetooth off and on again. It is only valid for wireless mice since wired mice do not use Bluetooth at all.

1. Click the Bluetooth icon at the top of your screen.
   
2. Turn off Bluetooth.
   
3. Wait a moment and turn it back on.
4. Check if your mouse is still lagging.

Replace mouse batteries

Low battery levels are a cause of mouse malfunctions. Remove the old batteries, replace them with new ones, and try connecting the mouse to your Mac again.

Fresh batteries are often an excellent cure for strange mouse behavior and lag. You’ll want to monitor your power to keep charge levels high at all times.

Consider using a USB dongle

There are cases where Macs experience Bluetooth connections that don’t work properly and one way to fix it is by getting a Bluetooth USB dongle. These devices tend to be more stable.

However, the opposite can also occur. If a dongle is broken, try connecting the mouse to the computer directly (with a cable) and see if the lag goes away.

Free up RAM

An overloaded Mac can lag, meaning there are too many active processes running simultaneously. You’ll want to free up your CPU and RAM by closing programs. Is that how it works.

1. On your Mac, press Command + Alt + Escape to open the Mac Task Manager.
   
2. Look for applications that consume a lot of resources.
   
3. Select an application.
   
4. Click “Force Quit” to finish them.
   

You may notice something similar when playing. If your game settings are too high, you may experience frame drops, which is another result of lag. Your mouse and everything else will lag if your Mac doesn’t have resources to spare.

Fix Mouse Lag on MacBook on External Monitor

Mac users with an external monitor connected to their device may sometimes wonder why the external display is slower than usual. The resolution may be the cause.

Here’s how to adjust the resolution.

1. Open the System Preferences menu.
   
2. Go to “Displays.”
   
3. Click “Scaling.”
   
4. Change the resolution to something you prefer.

While in this setting, you can also adjust the refresh rate to ensure that both displays have the same rate. That usually eliminates the delay. Other times, it’s a hardware problem.

If the HDMI cable or other devices are the culprit, you will need to replace or remove them. There is no other way to solve this problem.

Smooth operation

When using a computer, there should not be any mouse lag as it will interfere with productivity. While the reason may not be apparent initially, trying the solutions one by one should resolve the issue. Sometimes unplugging and reconnecting the mouse is enough.
