Firstly, I always suggest you update the graphic drivers of your system as with the new update you will always get the bug fixes while gaming.

Once downloaded go ahead and install the drivers to update your graphic card to fix the Call of Duty Warzone 2.0 Stuttering PC problem.

End Background Apps

So if you are into gaming, you are well known about the effect of background apps such as Google Chrome. If the apps are running in the background, your system will consume more RAM and in turn lower the performance of your Game.

The same happened with Warzone 2. If apps are running in the background, it is one of the major causes of Warzone 2 lagging PC.

To disable background apps, right-click on the start menu and choose “Task manager”

Now, in the processes tab, whatever apps are running instead of Warzone 2, go ahead right-click on each app and choose the option “End task” to close the unnecessary apps running in the background.
