Many gamers found that there are certain CPU demanding games that are particularly affected by performance issues when enabling fullscreen optimizations.

3. Update your graphics driver

Your graphics driver is an essential piece of software that lets your system communicate with the graphics card. If it is outdated, it would cause noticeable performance problems. Therefore, when you experience random freezes when playing Warzone, you should make sure your graphics card is up-to-date. You’ll likely won’t be able to fix or prevent every single freeze, but updating graphics driver can help you keep them down. Moreover, driver updates include the latest patches for security flaws, fix problems, and sometimes even provide you with completely new features, all for free.

To update your graphics driver, you can either do it manually via the Device Manager or head to the manufacturer’s driver download page (NVIDIA / AMD) to download and install the exact driver for your system. This requires a certain level of computer knowledge and can be a headache if you aren’t tech-savvy. Therefore, we would like to recommend you use an automatic driver updater such as Driver Easy. With Driver Easy, you don’t need to waste your time hunting for driver updates as it will take care of the busy work for you.

Here’s how to update drivers with Driver Easy:

4. Turn off Windows 10 Game Mode

Game Mode is a feature introduced to Windows 10 to make gaming a much better experience. But there have been quite a few reports that Windows 10’s Game Mode has been causing a lot of problems with some major titles, including Call of Duty: Warzone. To reduce the chances of game freezes occurring, you’re supposed to disable Windows 10 Game Mode. Below are the instructions on how to do this.

1) On your keyboard, press the Windows + I keys simultaneously to open Settings.

2) Click Gaming.

3) Select Game Mode. Then click the toggle to turn Game Mode Off.

If that didn’t seem to mitigate the problem, move on to the next solution.

5. Turn off background apps

You may not know that many apps run in the background at all times – even the ones you never use! They use a portion of your system resources, making your machine run a little bit slower. And this may result in poorer programs performance. To avoid game interruptions, you can attempt to disable background apps while playing Warzone:

1) On your keyboard, press the Windows + I keys simultaneously to open Settings.

2) Click Privacy.

turn off background apps

3) Click Background apps. Under the section Let apps run in the background, toggle the button to turn it Off.

If you want to let certain apps run in the background, you can manually choose them by toggling the buttons and turning them On.

After you’ve done this, play Warzone and you should be able to have an enjoyable gaming experience without encountering random freezes.
