High CPU usage with low GPU usage can occur due to usingbuilt-in graphicsinstead of a dedicated GPU, outdated drivers, CPU bottlenecking, or poorly optimized games.

This will lead toFPS drops,CPUoverheating, and all kinds of issues. In order to help you resolve it, we put everything we can think of below.

How do I fix high CPU and low GPU usage?

1. Check GPU drivers

These symptoms usually mean that yourCPUis bottlenecking yourGPU, which is quite common if you have powerfulgraphicsand an outdatedCPU.

However, there are so many variables that, even though highly likely, we can’t say with certainty bottlenecking is the reason for highCPUand lowGPUoccurrence.

After you’ve removed a current driver, navigate to theNvidia/AMDwebsite. Under the download section, find an appropriate driver fitting yourGPUmodel and system architecture.

Alternatively, you can always rely on specialized software such asPC HelpSoft Driver Updaterto identify and update all your drivers in just a few minutes.

2. Tweak in-game setting

If you experiencehigh CPU while gaming, particularly on select games while others work fine, consider adjusting settings.

Most games should be run on high or ultragraphicssettings to avoid CPU burden. We can advise you to disable VSync and Antialiasing.

Also, increasing the resolution, and the details plus enabling Future Frame Rendering should make GPU work more instead of the CPU doing the majority of the work.

Some games will work much smoother on the DX12 option, so switch to it if possible. This might or might not affect FPS, but it’s worth a try.

3. Patch the affected games

This step is the continuation of the previous one. Some games, like Overwatch, suddenly started exhibiting this kind of behavior even though players have more than enough processing power to run it.

Seemingly, issues started suddenly in the third quartal of 2018 and we can blame thegraphics-improving patch for that.

This might or might not be the case for other games, but whether it’s a Battle.net, Origin, or Steam game, make sure it’s up to date.

Some issues got patched and the majority of players are enjoying seamless gameplay without aCPUthrottling aGPU.

4. Disable third-party apps active in the background

1.In theWindows Searchbar, typemsconfigand click on the first result to openSystem Configuration.

Navigate to theServicestab.
Check theHide all Microsoft servicesbox, then clickDisable allto disable all active third-party services.

4.Now, select theStartuptab and go toTask Manager.

5.Click any startup program you think might be interfering then selectDisable. We recommend that you disable all of them which are not essential.

6.ExitTask Manager, clickOKin the System Configuration window, and restart your PC.

When you’re experiencing high CPU usage but low GPU usage, it is a good idea to get rid of unused background apps. They can free up a lot of CPU memory, so that your PC will run better.

You can remove unwanted processes via Task Manager. Simply filter the active processes by CPU usage and end those which take up a lot of resources and you have no use for.

5. Disable all power-preserving modes

Power-preserving modes are a big no-no if yourCPUis falling behind theGPUin terms of processing power. Especially if you’re an avid gamer dealing with demanding AAA titles.

This means that both system and motherboard settings regardingless power consumptionshould be disabled.

6. Enable XMP in BIOS/UEFI

Enabling XMP or Extreme Memory Profile in BIOS will, at least slightly,improve RAM performance.

We know that RAM isn’t in a direct connection with the highCPU/lowGPUissues but it has its part in it.

This option allows for the faster-than-standard speeds of RAM and possibly will improve the overall PCperformancea little bit.

If your PC doesn’t have a strong configuration, you can usesoftware to improve its performance.

7. Use 4 cores if possible and try overclocking

To optimize the game for the general public, developers have to deal with thousands of different configurations. SomeGPU–CPUcombos, regardless of how capable, just won’t work as intended.

This might be the case here. If you’re running a multi-threadCPU, double-check the in-game settings and try switching to 4-thread option if available. For example, Battlefield 5 might do better on a 4-thread option.

In addition, if you can take more from yourCPUbyupping the clock speeds, we highly suggest doing it.

Just keep in mind that this requires some general knowledge about overclocking and software tokeep track about temperatures, voltage, andperformance.

The manufacturer speeds are usually much lower than the CPU is capable of meeting. Firstly, inform about your CPU online and then move to overclock.

This should, in the right circumstances, be quite a boost and a possible resolution for the problem at hand.

8. Reinstall the game

If none of the previous steps helped you with that one game that refuses to work as intended, consider reinstalling it. This process allows you to enjoy some ofthe best PC gameswithout errors.

Removing everythingand starting from scratch can be a painful and lengthy experience. Especially if you need to wait for hours for a game to download again.

However,PC games, like any other piece of software out there, can get broken. Configuration files can get corrupt (if you’ve made some hardware changes) or a bad update can break the game for you.

That’s why reinstallation isn’t such a bad idea after all. Just make sure you’ve backed up your saves and reinstall the game. After that, reboot your PC and give it another try.

Use several process managers to ensure that theCPUis indeed hitting high rates whileGPUis almost idle.

The issue is present on all versions and users reportedhigh CPU in Windows 11as well.

It’s important to pay attention tohigh CPU temperaturebecause it will damage your hardware if not addressed properly.
