Let’s find out if there’s a fix.


Modern Warfare/Warzone High CPU Usage – Is there a fix?

Update: Here’s how you can fix the issue

Use Process Lasso to limit CPU usage

For some reason, the game’s priority is set to high or above normal by default due to which the CPU usage is spiking. This is also leading to lags in other apps such as discord.

Process Lasso is a software that helps you in limiting the CPU usage of a particular app. Download the software and use it accordingly, I was able to drop my CPU usage by almost 20% after using the software. Also, try switching between hyperthreading on/off, this also has a considerable improvement.

You can also turn the priority down by the steps given below.

Turn Down Game Priority

  • Press CTLR + Shift + ESC to open task manager
  • Find The Call of Duty: Modern Warfare and right-click > go to details
  • Now right-click on the process’s .exe file and set priority to “normal”.

Turn off The Second Monitor

Anyone who is trying to run the game with two monitor setups is getting dev errors and constant crashes. Turn the second monitor off while playing the game until the developer fixes it.

The article has been updated with inputs from Reddit user Im_Baggy.

There is no known culprit which is leading to the spike in CPU usage. Only a few users are reporting about this. I myself had no CPU usage problem. You can try toning the game settings by using this guide. Since the culprit is unknown finding a fix or troubleshooting it becomes difficult. Activision is recommending all users to submit reports using their client, so that is what I recommend you do.

I am actively looking for solutions to this problem and will be updating this article. Stay tuned!
