How to Fix GPU Usage Spike to 100% on Windows

Does your GPU usage spike to 100% even when you're running less resource-intensive processes on your device? Does your game lag, stutter, and sometimes freeze despite your top-notch hardware? When Task Manager or third-party graphics software shows that your GPU is overloaded, it could be due to a software or hardware issue.

In this article, we'll explore the reasons why your GPU might be throttling to its maximum limit and what you can do to fix it.

Why does GPU usage spike to 100%?

Several factors can cause your GPU usage to spike up to 100%, such as:

• GPU is not connected properly.
• Hardware failure has reduced the performance of the graphics card.
• You are overloading your GPU by running more resource-intensive tasks than it can handle.
• The game's resolution and frame rate are set too high.
• The GPU manufacturer recently released a driver update that you have not installed.
• Malware is silently draining your GPU resources.

With these causes in mind, let's take a closer look at how you can keep your GPU usage to a minimum.

6 Ways to Reduce GPU Usage When It Spikes

You can apply the following fixes to prevent GPU usage from reaching the maximum limit:

1. Check for hardware problems

First, make sure the problem isn't with your GPU hardware. To do that, boot into Safe Mode on Windows 11 ( or Windows 10 ), which loads only the necessary files and drivers. If your GPU usage spikes in Safe Mode as well, the problem could be hardware-related. So:

• Make sure the GPU is properly seated in the PCI slot.
• The power connections are plugged in correctly.
• Other connections are not loose.
• GPU doesn't overheat.

Once you’ve checked everything above and nothing seems to be the culprit, have your GPU checked by a qualified technician. But before you do that, you can try the other solutions listed in the article; they may be able to help you troubleshoot the issue.

On the contrary, if booting your device into Safe Mode completely resolves the issue; then it means that there is a software issue and not a hardware issue. Therefore, start performing the remaining fixes.

2. Stop overloading the GPU

You may be straining your GPU to the maximum possible extent, resulting in 100% GPU utilization in Task Manager. How to determine if this is true in your case? Easy; just check the GPU requests of the process that is consuming the most GPU resources in Task Manager.

For example, if your GPU usage spikes to 100% when playing a particular game, check the recommended or required system requirements for that game. If the GPU power required by the game is higher than what your graphics card can provide, the game may be using up all the processing power available. As a result, GPU usage may reach its limit.

To reduce GPU usage, simply closing such a task is enough. Here are the steps you need to follow to do this:

1. Right-click the Windows Start button and select Task Manager .

2. Sort processes by GPU usage by clicking on the GPU column.

3. Right-click the process at the top of the list and select End Task.

If the issue is specific to a specific process, such as playing a video game, you should optimize the game settings to get the best performance without overloading your GPU. Reduce the game resolution and adjust the frame rate to achieve a balanced result. Also, turn off unnecessary settings like overlays and instant replay.

3. Make sure your device is not infected with malware

The presence of malware can also put a strain on the GPU, which is one of the most overlooked causes of excessive resource usage. Malware like crypto hijackers infect devices with one goal in mind: to use system resources for mining and other purposes. But how can you tell if your device has been hacked? It’s easy!

In the Task Manager of the compromised device, you will find one or more shady processes using a lot of system resources. Therefore, you should follow the steps outlined above and filter out such shady processes. Once located, search for them on the web to see if they are problematic processes.

If so, perform a Microsoft Defender offline scan or use a third-party antivirus program to locate and remove them.

4. Update graphics card driver

Your hardware’s graphics processing can also be affected by outdated graphics drivers. So, if you haven’t updated your graphics drivers in a while, now is the time to do it. Not sure how to do it?

5. Disable hardware acceleration

Another lesser-known cause of GPU resource consumption is hardware acceleration. This process involves offloading graphics-intensive tasks to dedicated hardware, such as the GPU, to reduce the workload on the CPU. While this improves CPU performance, it puts a strain on the GPU.

Many programs, including web browsers, games, graphic design software, and countless others, come with this feature, so if you find an application that is consuming too many resources and has this feature enabled, you should turn it off.

6. GPU Overclocking

Is your GPU running at overclocked settings? If so, that could be the cause of the problem.

When done incorrectly, overclocking can severely degrade a GPU's performance. GPUs that are overloaded, don't have enough airflow through them, or are running at the wrong voltage are susceptible to instability. Worse yet, using a GPU in such situations can cause physical damage to the hardware.

So if you’re running your GPU at overclocked settings, now is the time to change it back to default. You should overclock your GPU if possible. While you won’t get the same performance as before, the overall efficiency boost will prevent GPU usage from spiking.
