100 GPU Usage

100% GPU Usage: Should I Worry?

Many gamers freak out when they find out their favorite game uses 100% of their GPU. They think it is a bad thing and need to do something to fix it.

But the truth is that 100% GPU usage is not a bad thing per se, as it totally depends on the conditions under which that 100% is being reached.

If you want to know why your graphics card is running at 100%, when you should worry about it, and what to do if it happens, just keep reading.

What does 100% GPU usage mean?

The percentage of your GPU usage basically tells you how much of its processing power is being used at any given time.

So, when your graphics card runs at 100%, it means that it’s being maxed out. This means your system is well optimized, and no component is bottlenecking it, which is a good thing.

However, 100% GPU usage is not always a good thing. If you’re getting 100% GPU usage when idle, it means something is wrong.

This brings us to the next section.

Should I worry about 100% GPU usage?

As I told you, it depends on the conditions, and this is what we are going to discuss now.

Games tend to be very demanding, especially if they are graphically intensive. So, it is totally fine if your GPU usage is 100% when playing demanding games.

2. 100% GPU Usage When Playing A Less Demanding Game

Now, if you are playing a less demanding game and still getting 100% GPU usage, then probably something is wrong.

This means that your system is using 100% of your GPU to run a game when it doesn’t need that much processing power to run properly.

There can be several reasons for this. It could be a driver issue, a bottleneck in your system, or simply because the game is not optimized.

There is also the possibility that your GPU is old and is actually using 100% of its processing power to run a not demanding game.

How to fix high GPU usage?

1. Monitor Your GPU Usage

The first thing to do if you think your GPU is being used too much is to monitor it.

There are several ways to do this, but the most popular and easiest way is to use Windows Task Manager.

To do this, simply open the Task Manager and go to the “Performance” tab. There you can see if it is reporting high GPU usage.

If you want to monitor GPU usage while playing a game, you can download a third-party tool like MSI Afterburner. This will allow you to see your GPU usage in real-time while playing games.

To do that with Afterburner, download it and then open it. Once you have opened it, go to the settings and then to “Monitoring.” Here you will see all the options that you can enable to monitor your GPU usage.

Click “Display On-Screen Display” and click apply.

Now, you will see your GPU usage in real-time while playing games.

After monitoring your GPU usage for a few hours, you will know for sure if you have a GPU usage problem.

2. Reinstall Your GPU Drivers

A corrupted GPU driver is the most common cause of high GPU usage. But the good news is that it is a very easy problem to fix. All you need to do is uninstall the old drivers and install the latest ones.

To do this, go to “Device Manager,” right-click on “Display Adapters,” and then select “Uninstall Device.”

Once you have uninstalled the drivers, restart your PC and then install the latest drivers from the manufacturer’s website.

3. Disable Background Apps

Another common reason for 100% GPU usage is background apps.

There are several programs that can use up your GPU resources without you knowing. To fix this, type MSConfig in the search bar and open it.

Once you have opened it, go to the “Services” tab, click on the option to “Hide all Microsoft services,” and then click on the “Disable all” button.

Now, restart your PC and check if the problem is fixed. What you did by doing this is you disabled all the programs that run in the background but the ones that are essential for Windows to run (Microsoft services).

Then re-enable them one by one to see which one is causing the problem.

4. Use A Malware Cleaning Tool To Scan And Remove Viruses

Another possible cause of 100% GPU usage is a virus or malware infection. If you have a virus or malware on your system, it can use up your resources without you knowing.

Over the last years, a lot of mining malware has been released. These viruses use your GPU to mine cryptocurrency without your permission, and the attackers get all the rewards.

The malware cleaning tool I recommend is Malwarebytes. This very effective free tool will remove any malware from your system.

To use this tool, simply download it and then run it. Once you have opened it, click on the “Scan” button to start scanning your system for malware.

Once the scan is finished, you will see a list of all the malware that has been found on your system.

Click on the “Quarantine” button to remove all the malware from your system.

After you have quarantined all the malware, restart your PC and monitor your GPU usage again to see if the problem is fixed.
