Many users have reported that their mouse pointer lags after they have updated to Windows 10. At first, it seems a Windows 10 issue. However, not all Windows 10 users are facing this issue. So, we can be confident that this issue is caused by some hardware or software interfering with the Mouse.
Like many other Windows issues, there is no single solution for this issue. However, you can try different methods one by one to rule out some common causes of mouse pointer lag in Windows 10.
Here are some common reasons for mouse lag in Windows 10 ordered by importance.
Method 1: Check Mouse Settings
Before you try other solutions, it is wise to rule out the issues with your mouse. The best option is to try another mouse. If your mouse pointer works smoothly with the other mouse, it is certainly a problem with your mouse hardware or mouse driver. To uninstall and reinstall the mouse driver, follow these steps.
Right-click on Start button and choose Device Manager.
Double-click on the Mouse and other pointing devices to expand the group.
Right-click on the name of your mouse and click Uninstall.
Go to the toolbar in Device Manager and click Scan for hardware changes (using the Alt Key and the Arrow Keys on the Keyboard). Windows will reinstall the drivers for your mouse, if it doesn’t reboot the PC/Laptop by holding the power button for a couple of seconds.
If this does not solve the issue or you have a mouse with additional features, go to the manufacturer’s website and download the mouse driver compatible with Windows 10.
Method 2: Update your Graphic’s Driver
When you upgrade your Windows, driver compatibility is often a major issue. Check your graphics card manufacturer if they have released an updated driver for Windows 10 (they usually have). If it has released, install the latest drivers for your graphics card by all means.
Check your mouse after installing the latest drivers.
Note: If your mouse is still lagging, change resolution and refresh rate in the graphics card utility provided by your graphics card manufacturer instead of the standard Windows 10 Settings.
If none of these methods works, move to the next solution.
Method 3: Check Cortana
Some users reported that their mouse worked smoothly after they disabled Cortana, Microsoft’s intelligent personal assistant. To disable Cortana, follow these steps.
- Open Cortana.
- Click the notebook icon in the Options pane on the left side of Cortana.
- Select Settings from the list.
- A number of options will appear. Turn off “Cortana can give you suggestions, ideas, reminders, alerts and more.”
Check if your mouse works smoothly. If not, try the following solution.
Method 4: Check Local Area Network Settings
Some users reported that they got rid of mouse lag in Windows 10 after they disabled LAN and used the wireless card to connect to the internet. To do this, follow these steps.
Right-click on the Start button and choose Control Panel.
Click on View by dropdown menu and choose Large icons or Small icons.
Click on Network and Sharing Center.
Click Change adapter settings in the left pane.
Network Connections window will appear. Right-click on the name of your LAN card and choose Disable.
In the same Network Connections window, right-click on the name of your Wi-Fi card and choose Enable.
If you have a Realtek sound card, try the following.
Method 4: Check Realtek Card Settings (If Applicable)
Some users solved the mouse lag issue by disabling a program related to Realtek audio driver. To disable automatic startup of this program, follow these steps.
Right-click on an empty area on your taskbar and click Task Manager.
Find and click on exe, right-click on it and choose End Task.
If this solves the issue, click Disable button at the bottom right corner of the Task Manager window to stop automatic start of this program.
Note: The users didn’t report any issues with sound after disabling this program.
As I have already mentioned above, several things can cause the mouse lag issue. If the above methods do not work, you can try disabling suspected drivers. Additionally, open the Task Manager and look at the CPU, memory, and disk usage of different apps. If an app is excessively using any of these resources, it may be a cause of mouse lag. Try closing such app. You can close an app within the Task Manager window. Just right-click on the app and choose End task. A Little experimentation will most probably solve the mouse pointer lag issue.
