But, bottlenecking isn’t always the reason for the strange usage discrepancy between CPU and GPU. High CPU usage and low GPU usage might occur for various reasons. This will, of course, lead to FPS drops, CPU overheating, and all kinds of issues. In order to help you resolve it, we put everything we can think of in the list below.
Why is my CPU high and GPU low?
Your GPU is probably being underutilized for one of the following reasons: you are making use of the integrated graphics on your computer, there is a problem with the graphics driver, you are experiencing a bottleneck caused by your CPU, or the game you are playing isn’t optimized. As our readers reported facing the high CPU and low GPU situation in Warzone, FiveM, Fortnite, and CyberPunk, we found out that if you don’t have the latest version of the game installed, it can cause such discrepancies. Moreover, you can check out our guide on how to reduce CPU usage while gaming if updating the game doesn’t do the trick. The issue is present on all versions and users reported high CPU in Windows 11 as well. To fix it, you just need to disable all background applications that aren’t essential. It’s important to pay attention to high CPU temperature because it will damage your hardware if not addressed properly.
How do I fix high CPU and low GPU usage?
1. Check GPU drivers
These symptoms usually mean that your CPU is bottlenecking your GPU, which is quite common if you have powerful graphics and an outdated CPU. However, there are so many variables that, even though highly likely, we can’t say with certainty bottlenecking is the reason for high CPU and low GPU occurrence. After you’ve removed a current driver, navigate to the Nvidia/AMD website. Under the download section, find an appropriate driver fitting your GPU model and system architecture. You can perform a good and fast driver management if you try out a reliable third-party software. This way, you will not have to manually search for the latest graphic card drivers. Use professional software that will improve your computer’s performance. It is based on a simple, fast and secure technology for your graphic card.
2. Tweak in-game setting
The likes of Overwatch, Battlefield 5, Black Ops 4, and PUBG are dominating the list. The funny thing is that affected users haven’t experienced strange CPU/GPU behavior on other titles, some even more demanding. Disclaimer: this program needs to be upgraded from the free version in order to perform some specific actions. This means that something concerning that exact game is causing issues. And, in this case, we would suggest disabling all CPU-depending graphical features and enabling GPU ones. Moreover, you should refer to our dedicated guide on how to lower CPU usage in games. Some even say that most games should be run on high or ultra graphics settings 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 the graphics-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 a CPU throttling a GPU.
4. Disable third-party apps active in the background
In the Windows Search bar, type msconfig and click on the first result to open System Configuration.
Navigate to the Services tab.
Check the Hide all Microsoft services box, then click Disable all to disable all active third-party services.
Now, select the Startup tab and go to Task Manager.
Click any startup program you think might be interfering then select Disable. We recommend that you disable all of them which are not essential.
Exit Task Manager, click OK in 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. SPONSORED
5. Disable all power-preserving modes
Power-preserving modes are a big no-no if your CPU is falling behind the GPU in terms of processing power. Especially if you’re an avid gamer dealing with demanding AAA titles. This means that both system and motherboard settings regarding less power consumption should 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 high CPU/low GPU issues but it has its part in it. Bottlenecking is a common problem, as all parts (mainly CPU) of configuration don’t function well together. This option allows for the faster-than-standard speeds of RAM and possibly will improve the overall PC performance a little bit. If your PC doesn’t have a strong configuration, you can use software to improve its performance. Whether that will be enough to overcome the CPU bottleneck or not, we can say with certainty.
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. Some GPU-CPU combos, regardless of how capable, just won’t work as intended. This might be the case here. If you’re running a multi-thread CPU, 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 your CPU by upping the clock speeds, we highly suggest to do it. Just keep in mind that this requires some general knowledge about overclocking and software to keep track about temperatures, voltage, and performance. 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 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 of the best PC games without errors. Removing everything and 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 breaks 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. Make sure to use several process managers to make sure that the CPU is indeed hitting high rates while GPU is almost idle.
9. Reinstall Windows
The system might be at fault as well, so that’s another thing you can do to reduce high CPU usage. If you’re running Windows 7, consider disabling Windows Update as its service is known for skyrocketing CPU usage. Most recent titles require Windows 10 in order to work and, all annoyances aside, this system proved to be the best for gaming. Therefore, consider upgrading to Windows 10 or, if you’re already running Windows 10 on a 64-bit architecture, try reinstalling it and running the game again. This will take some time but it helped some users normalize CPU/GPU performance. An efficient solution you should try in this case is to reinstall Windows 10.
10. Replace or add some fresh hardware
And finally, we came through with this Captain Obvious suggestion. But sometimes your CPU is just not enough. Combining an older CPU with a GTX 1070 won’t do you any good. This is because the CPU will always try to keep up with the top-notch graphics processor. And it will fail every time. That’s why minimum requirements might be misleading and often are. For the majority of games where users reported the high CPU and low GPU usage, a powerful gaming processor is a must. Basically, if you want top performance, buy top CPU. As simple as that. Add some RAM along with the new CPU and the bottlenecking will be a thing of the past. Alternatively, clean and optimize your current memory in order to avoid purchasing additional ones.
