How to fix Call of Duty: Modern Warfare II and Warzone 2.0 input lag issues on Xbox

You may experience noticeable input delay when playing Call of Duty: Modern Warfare II and Call of Duty: Warzone 2.0 on your Xbox console.  

To see how you can reduce latency for these Xbox One, Xbox One S, Xbox One X, Xbox Series S and Xbox Series X games, you can follow the steps laid out in this tutorial at Seeking Tech. 

1. The first step you can try is to make sure that your television set has a Game Mode, Game Optimizer Mode or similarly named mode activated.  

This is the best picture setting for playing games as it will lower the input lag. 

2. You should also make sure that you aren’t using any A.I. processing on your TV screen as these features may add latency. 

3. You are able to play Modern Warfare 2 and Warzone 2 at 120 frames per second on the Xbox Series S and Xbox Series X. By doing so, you will get a much smoother experience that should also result in lower input lag.  

To enable this mode, make sure that your television set or monitor supports a 120 Hz refresh rate. Afterwards, you need to go to the Settings menu of your Series S or Series X and then go to General > TV & display options. From the General – TV & display options menu, make sure you change the Refresh Rate setting to 120 Hz. 

While enabling 120 Hz will lead to less sharpness and visual fidelity, you should end up getting a faster input response. 

4. To further reduce input lag, you should also enable Variable Refresh Rate on your Xbox Series S or Xbox Series X. If your TV or monitor supports this feature, then make sure you turn it on from the screen’s settings menus.  

On your Series S or Series X, you then need to go to General > TV & display options > Video modes.

From there, you need to check the “Allow variable refresh rate” box.  

5. If you are using a wireless Xbox controller to play Call of Duty: Modern Warfare II and Call of Duty: Warzone 2.0 than we recommend that you plug the gamepad directly into one of the USB ports of your Xbox One, Xbox One S, Xbox One X, Xbox Series S or Xbox Series X console.  

This is because a wired connection should lead to a faster response when compared to wireless. 

6. The same logic should also apply to the internet connection. So, if possible, we recommend using a wired Ethernet cable to connect your Xbox online instead of using Wi-Fi.  

7. It is a good idea that you update the games, your console, your screen, as well as your controller. The new versions may come with improvements when it comes to reducing the input latency. 

8. If you are still experiencing a lot of lag, then you can try switching to another television screen or monitor. Some screens are better equipped at reducing latency when compared to others.
