Fix: Call of Duty Vanguard Mouse Not Working or Lags Badly

Sledgehammer Games and Activision has done a great job by releasing Call of Duty: Vanguard as one of the first-person shooter video games in 2021. It’s currently available for Windows, PS4, PS5, Xbox One, and Xbox Series X|S platforms. We can consider it one of the best WWII FPS games in the market. However, there seem to be some flaws in the Call of Duty Vanguard game such as Mouse Not Working or Lags Badly issue on the PC.

Now, if you’re also one of the victims of this same issue while playing the COD Vanguard title then you’re not alone. Obviously, there are some possible reasons behind the lag or stutter with the mouse during the gameplay that we’ll try sorting out for you. Well, gaming on a PC is way handier than on a console, but it also brings some unwanted issues. Mostly upgrading the game version or the mouse driver may fix this issue.

But sometimes the mouse not working or lags or an unresponsive issue may appear due to other reasons such as connectivity issues with the input devices (mouse), outdated Windows, corrupted or missing game files, Windows scaling issues, higher graphics settings in the game, etc. Meanwhile, mouse DPI or issues with the overlay apps, etc can ruin your FPS gameplay experience so easily.

1. Update Mouse Driver

It’s always required to update the mouse driver on your Windows system so the in-game mouse lags or stutters may not appear again. To do this:

Right-click on the Start Menu to open up the Quick Access Menu.
Click on Device Manager from the list.
Now, double-click on the Mice and other pointing devices category to expand the list.
Then right-click on the mouse that you’re using.
Select Update driver > Choose Search automatically for drivers.
If there is an update available, it’ll automatically download and install the latest version.
Once done, make sure to reboot your computer to change effects.

2. Run the game as administrator

Make sure to run the game exe file as an administrator to avoid user account control regarding privilege issues. You should also run the Steam client as an administrator on your PC. To do this:

Right-click on the COD Vanguard exe shortcut file on your PC.
Now, select Properties > Click on the Compatibility tab.

Make sure to click on the Run this program as an administrator checkbox to checkmark it.
Click on Apply and select OK to save changes.

3. Update Windows

Updating Windows OS build is always essential for PC users as well as PC gamers to reduce system glitches, compatibility issues, and crashes. Meanwhile, the latest version mostly includes additional features, improvements, security patches, and more. To do that:

Press Windows + I keys to open up the Windows Settings menu.
Next, click on Update & Security > Select Check for updates under the Windows Update section.
If there is a feature update available, select Download and install.
It may take a while to complete the update.
Once done, restart your computer to install the update.

4. Disable Overlay Apps

It seems that a couple of popular apps do have their own overlay program that can eventually run in the background and cause issues with the gaming performance or even launching issues. You should turn them off to fix the issue by following the steps below:

Disable Discord Overlay:

Launch the Discord app > Click on the gear icon at the bottom.
Click on Overlay under App Settings > Turn on the Enable in-game overlay.
Click on the Games tab > Select COD Vanguard.
Finally, turn off the Enable in-game overlay toggle.
Make sure to reboot your PC to apply changes.

Click on Gaming > Go to Game Bar > Turn off Record game clips, screenshots, and broadcast using Game bar option.

If in case, you’re unable to find out the Game Bar option then just search for it from the Windows Settings menu.

Disable Nvidia GeForce Experience Overlay:

Launch the Nvidia GeForce Experience app > Head over to Settings.
Click on the General tab > Disable the In-Game Overlay option.
Finally, restart the PC to apply changes, and launch the game again.

Also do keep in mind that you should disable some other overlay apps like MSI Afterburner, Rivatuner, RGB software, or any other third-party overlay apps that run in the background always.

Launch the Battle.net app on the PC.
Log in with your Battle.net account > Select Call of Duty: Vanguard.
Make sure to follow the on-screen steps to install or update the game. (if available)

7. Disable Windows Scaling

Windows OS has a screen scaling feature that automatically increases and adjusts the text size, apps, and other visuals on the screen to make them easier to watch or read. However, if you’re encountering any kind of visibility glitch then make sure to disable the Windows Scaling feature on the PC. To do this:

Press the Windows + I keys to open Settings.
Click on System > Set the Change the size of text, apps, and other items to 100%.

Click on Change high DPI settings > Ensure to checkmark the Override high DPI scaling behavior checkbox to select it.
Select Application > Click on OK.
Finally, click on Apply to save changes.

9. Lower the in-game graphics

Sometimes using the higher graphics settings in the game may cause game lags or other mouse stutters. So, reducing the in-game graphics settings may fix the lagging or stuttering issue up to some extent. It can help a lot if your PC hardware is on the lower side or becomes outdated. Launch the COD Vanguard game on the PC and then head to the graphics settings menu to adjust the graphical options to low or medium.

10. Try Changing the Mouse DPI

The mouse sensitivity can be measured in DPI (dots per linear inch). It indicates that the higher your DPI level on the mouse, the faster it will move across the screen seamlessly. It particularly helps in FPS games when each and every second or movement is essential. However, the higher DPI settings on the mouse can also cause multiple glitches or performance-related issues whatsoever.

No matter which mouse software you’ve installed or just using the default Windows mouse settings, try changing or lowering the mouse DPI at an optimal level to cross-check the issue. Try creating a new mouse DPI profile for third-party software and check for the issue again.

11. Disconnect Other Peripherals

It’s recommended to disconnect all other useless peripherals connected to the PC except for the mouse and keyboard. Then try checking out the Call of Duty Vanguard Mouse Not Working or Lags issue.

Search for Control Panel and click on it to open.
Now, go to the Mouse section > Click on Pointer Options.
Uncheck the Enhance pointer precision option > Click on OK to save changes.

13. Perform a Clean Boot

Some of the apps and their services may start automatically while booting the system right away.

If you’re also feeling the same, make sure to perform a clean boot on your computer to check for the issue. To do that:
