Warzone 2 High CPU Usage and Low GPU Usage Fix

The Call of Duty franchise has a long history of producing successful titles, making it a popular choice among action FPS gamers. The newest addition to the franchise is the Warzone 2.0 online battle royale game, which is part of the Modern Warfare II (2022) edition. However, despite being a successor to the previous Warzone title, Warzone 2.0 has several bugs and errors that cannot be overlooked. One of the issues faced by players on PC is the Warzone 2 High CPU Usage and Low GPU Usage, which can be frustrating to deal with.

The game has low system requirements for playing on a Windows computer, but many players are experiencing high CPU usage and low GPU usage at the same time, which is causing a lot of frustration. This issue is making it difficult for affected players to get into the game or continue playing multiplayer sessions online. Additionally, many players are encountering in-game stutters, glitches, lags, and other common issues.

Fix: Warzone 2 High CPU Usage and Low GPU Usage

Fix: Warzone 2 High CPU Usage and Low GPU Usage

Some unfortunate Warzone 2 players have claimed that almost 80% or higher CPU usage is getting consumed on the machine while running the same. Meantime, the GPU usage becomes low enough which indicates there is some issue with the compatibility or the proper usage of system resources. As a result, the game starts showing hiccups and crashes quite often which becomes hard to handle.

Luckily, there are a couple of workarounds mentioned below to fix this issue. Now, if you’re also one of the victims encountering such an issue then make sure to follow all methods one by one until the problem gets fixed. So, without further ado, let’s jump into it.

1. Run the game as Administrator

Make sure to run the game app file on your PC as administrator access to allow the User Account Control (UAC) access to the system. In some cases, your system requires the UAC access permission to run a program which is quite important. By following the steps below you’ll have to allow the admin access for once and it won’t ask you for the same again. To do so:

  • Go to the installed Call of Duty: Warzone 2 game directory.
  • Right-click on the game application file on your PC.
  • Click on Properties > Click on the Compatibility tab.

  • Click on the Run this program as an administrator checkbox to enable it.
  • Once done, click on Apply and then OK to save changes.
  • Finally, run the game to check for the issue.

Please Note: If you’re using the Steam or Battle.net client on the PC, then perform the same steps for the respective launcher to grant the admin access.

2. Use a Dedicated Graphics Card

It’s highly recommended to use the dedicated graphics card on the PC to run graphics-intensive games like COD MWII smoothly. It’ll reduce game stutters, lags, and frame drops apart from GPU not using 100% issues. If you don’t know which settings you need to adjust, then follow the steps below.

For Nvidia GPU:

  • Right-click on the blank desktop screen > Open Nvidia Control Panel.
  • Go to 3D Settings > Click on Manage 3D Settings.
  • Open Program Settings > Select Call of Duty: Warzone 2 from the list.
  • Select Preferred graphics processor for this program from the list.
  • Once done, you can see it as High-Performance Nvidia Processor.
  • Make sure to save changes and reboot the PC.

For AMD GPU:

  • Right-click on the blank desktop screen > Open AMD Radeon Settings.
  • Head over to Additional Settings > Go to Preferences.
  • Click on Power > Click on Switchable Graphics Application Settings.
  • Select Call of Duty: Warzone 2 from the list.
    • If the game is not visible, select Add Application to include the game.
  • Once done, select High Performance from Graphics Settings.
  • Finally, reboot the PC to apply changes.

3. Update GPU Drivers

An outdated or corrupted graphics card driver can trigger multiple issues with the games or system performance while running programs. It’s highly recommended to check the graphics driver update. To do so:

  • Press the Win+X keys to open the Quick Link Menu.
  • Click on Device Manager from the list > Double-click on Display adapters.
  • Right-click on the dedicated graphics card that you’re currently using.

Device Manager Update Display Adapter

  • Click on Update driver > Choose Search automatically for drivers.
  • If there is the latest update available, it’ll automatically download & install the latest version.
  • Once done, restart the computer to apply changes immediately.

Alternatively, you can manually download the latest version of the graphics driver and install it on the PC via the official website. Make sure to download the graphics driver file respective to your graphics card model and manufacturer. Nvidia graphics card users can update the GeForce Experience app via the Nvidia official site and AMD graphics card users can visit the AMD website for the same. While Intel graphics users can visit here.

4. Disable fullscreen optimizations

Sometimes turning off the fullscreen optimizations by the Windows system for your specific game application file should fix the compatibility issues for some PCs. Though it comes disabled by default, you should cross-check it to ensure that the fullscreen optimization isn’t enabled. To do this:

  • Open the Steam client > Click on Library.
  • Right-click on Call of Duty: Warzone 2 > Click on Manage.
  • Click on Browse local files > Head over to the Call of Duty: Warzone 2 installed folder.
  • Right-click on CallofDutyWarzone2.exe > Click on Properties.
  • Go to the Compatibility tab > Ensure to click on Disable fullscreen optimizations to checkmark it.
  • Once done, click on Apply and then OK to save changes.

5. Close Background Running Tasks

Unnecessary background running tasks or programs can eat up a lot of system resources like CPU or Memory usage literally reducing system performance. Hence, the startup crashing, lagging, and not loading issues appear quite often. Simply, close all the unnecessary background running tasks completely. To do this:

  • Press the Ctrl+Shift+Esc keys to open up Task Manager.
  • Now, click on the Processes tab > Click to select tasks that are unnecessarily running in the background and consuming enough system resources.
  • Click on End Task to close them one by one.
  • Once done, restart your system.

6. Use the Best Performance Power Plan

It’s also highly recommended to change the power plan on the computer because the Windows system basically uses the Balanced power plan by default. But it reduces performance which can be improved by changing the power plan. Keep in mind that the performance plan can consume higher power. To do so:

  • Press the Win+R keys to open the Run dialog box.
  • Type Control Panel in the field and click on OK from the search result to open it.
  • Now, search for Power Options (Power & battery) and open it.

  • Click on Best Performance > Reboot your PC to save changes immediately.

7. Tweak In-Game Graphics Settings

You can also change the in-game graphics settings to check if the problem is still appearing or not. Some of the in-game graphics settings may help you to play the game better and achieve a higher framerates count.

11. Try Disabling Overlay Apps

Sometimes a couple of applications may come with an additional overlay app that basically helps the streamers or gamers a lot. However, these overlay apps can eventually conflict with the game files to run smoothly and may cause several issues like FPS drops, black screen issues, lags, glitches, etc. You should try disabling the overlay apps manually before launching the game again to cross-check whether the crashing issue has been fixed or not.

If in case, you’re using any other antivirus program on your PC then make sure to turn it off.

13. Perform a Clean Boot

Multiple users claimed that performing a clean boot on the PC did fix the system boot-up issue because some apps or tasks start at the very beginning. These tasks run all the time and consume a lot of system resources. You should follow the steps below to do so:

  • Press the Win+R keys to open the Run dialog box.
  • Type msconfig and hit Enter to open System Configuration.

Sometimes overclocked CPU or GPU on the PC might cause conflicts with the other hardware which may trigger a bottleneck issue. It’s better to temporarily disable or restore the overclocked CPU/GPU to the factory default so that you can check out the potential reason behind the crashing issue. There are multiple tools available online to adjust overclocked CPU or GPU on the PC such as MSI Afterburner, Riva Tuner, AMD Ryzen Master, EVGA Precision X, etc.
