Gpu usage 0 while gaming

What is the worst thing that can happen to gamers while they are playing? It is a hindrance in the video game due to GPU issues. This is both annoying and takes out all the fun from gaming.

The low performance of a GPU can cause the usage of GPU to drop to 0 during gaming. If you are running any graphics-intensive programs on your system, the usage of the GPU should be at least 99% or even better, 100%. This is the best usage you can get out of your GPU.

Usage below 99% or 100% can cause a low GPU usage problem in your system. This usually happens when the GPU is not working at its highest capacity. Hence, the resources of the GPU are not being utilized completely. Thus, leading to the GPU usage problem or GPU usage drops to 0.

I have dealt with this problem quite a few times and tried various methods to solve it. I will list the causes and fixes of this issue below for your understanding. Hope it helps!

GPU Usage Drops: Understanding the Basics

First lets understand the functions/roles of GPU. What is it and what does it do before we can understand and fix usage drops.

A GPU or the graphics processing unit alters the memory or sometimes manipulates it. This is done to increase the speed of image creation. The images that are created are then sent to the display screen for the users. GPUs are used in mobile systems, gaming consoles, personal computers etc.

The GPU acts and aids the computer system in every task that is being performed. GPU is working continuously from gaming, video streaming, and file editing to simply browsing the internet using an internet browser.

Graphics Processing Unit can work without having to route the data through the CPU to the RAM of the system. GPU does this with the help of VRAM. Due to this reason, the GPU was first named the Graphics Processor Unit in the 1970s. And also owing to its ability to function independently from the RAM.

Causes and Fixes of GPU Usage Dropping to 0

There maybe several reasons for the usage of GPU to drop. Some of these reasons are:

  • Game-related
  • GPU overheating
  • Game Launcher Optimization
  • Exploit Protection
  • An issue with the GPU settings/priorities
  • NVIDIA profile inspector
  • Game settings optimization
  • Power Supply issue
  • Bottleneck
  • SLI/CrossFire Issue
  • Video Driver Issue

1. Game-related issue encountered in Skyrim, Overwatch etc.

It may be hard to believe but sometimes the issue may not lie in the GPU or your system at all. Many games are designed such that they are CPU dependent. Since the optimization etc. takes up a lot of the resources, it leads to low usage of GPU.

To fix this you will have to rely on updates from the game developers or patches designed specifically to fix this issue. These issues are common in video games like Skyrim, Overwatch, Bannerlord, andDragon Age Inquisition to name a few.

2. GPU Overheating

GPU Overheatingis a common issue in many systems. This can happen for many reasons like overclocking, inadequate supply of air or improper ventilation, poorly functional fans etc.

Improper Ventilation

Ventilation is extremely important in the maintenance of a GPU’s temperature. Poor ventilation causes the system to heat up quickly, thus dropping performance.

For this purpose, you have to make sure that there is no friction or extra hindrance in the ventilation system of the GPU. As this may be blocking the proper movement of the fans.


Sometimes people tend to increase the clocking speed to increase the performance of their system. However, what they do not realize is that it may damage the GPU in the longer run.

It is better to keep the clocking rate in check. Do not increase it. Increased clock rate for prolonged period of time will definitely affect GPUs usage.

Fans Issue

If the fans are not functional in the GPU, it is very likely that your GPU will overheat pretty quickly. Fans are quite essential in the GPU to maintain its temperature and it is a better practice to check the fans regularly.

Make sure that they are fully functional and replace the faulty fans as soon as possible.

3. Game Launcher Optimization

The game launcher optimization for full screen is a feature that is available in most GPUs. When enabled the feature forces GPU to optimize the game further based on the full screen. This may be causing the GPU to work more than it normally does.

Most issues with stuttering and GPU usage involve the display settings and resolution of the system. So, disable this feature by going to the settings in the game launcher. You can also fix it by right-clicking on the game shortcut on the folder you have your game.

4. Exploit protection

Exploit protection is a Windows feature that helps in protecting the windows against certain malware. The malware that uses exploits to spread and infect the system or certain apps.

If the feature of control flow guard is not active for an app or game that is causing the GPU usage to drop, it may get difficult for the GPU to maintain its usage. For this purpose, do the following steps,

  • Go to search.
  • Search for exploit protection in the windows search bar.
  • Then, click on the program settings.
  • Click on the add button.
GPU usage drops to 0
  • Click on the choose exact file path option.
  • Choose the launcher of the game.
  • In its settings, turn on the control flow guard.
fix for GPU usage drops to 0
  • Apply the settings and refresh your screen.

5. An issue with the GPU settings/priorities

The graphics card come with some default settings and priorities set for them. These settings are set by your vendor. Unless you have deep knowledge of your system and the things you are doing, it is suggested to not play with these settings.

Some people may change the settings and priorities for performance etc., which may disrupt the balance of the GPU. To make sure that this does not happen, do not change the settings and if done, it is good to change them back to default.

6. NVIDIA Profile Inspector

You can download the NVIDIA profile Inspectorand change the settings for multiple profiles of the NVIDIA display drivers. It is an open source third-party app.

You can also set the desired frequency and speed of the fans in the GPU by using this tool. Users might feel that the drop in usage maybe because of the irregular fan speed or frequency. You can alter that by using this tool.

7. Optimize the game settings

As I have mentioned before, sometimes the issue lies in incorrect optimization of the game or features. Like the screen resolution that may be causing a drop in the usage of your GPU.

The game’s settings account for its performance like any other software or device. To fix this issue,

  • Go to settings of the game and then go to the display settings.
  • Set the display settings as either windowed mode or windowed borderless.
  • This will allow you to set the graphics according to your preference.
  • Set the settings such that the game is optimized according to your GPU’s capability, capacity, build, and other features.

8. Power Supply Can be Underpowered for Your System

A low powered or underpowered PSU can lead to a drop in the usage of your GPU. This happens because the power supply does not have enough power to transmit to the GPU and the CPU. Hence, both of these components will face difficulty in functioning properly.

Adequate and efficient power supply is extremely important for your gaming system. Also, check the connectors of the PSU by using a multi-meter.

9. Bottleneck

At times, the issue does not lie with the game or the GPU at all. The real problem is with the CPU. This means that the CPU does not have enough power to support a strong GPU.

Pairing a strong state of the art GPU with an old or relatively weaker CPU will result in a bottleneck system. Similarly if you pair a very strong CPU with an older GPU, this will result in a CPU bottleneck. Bottleneck can cause CPU usage drop to 0.

You really want to avoid both situations. To do that, it is best to pair compatible CPU and GPU in terms of their strength. For CPUs 60 to 70 Percent of usage is acceptable while for GPUs it should be 99 to 100 percent.

A tool to check the usage of these components is MSI afterburner. You can use it to check for the usages of your respective devices.

10. SLI/CrossFire Issue

SLI and crossfire both are used for the same purpose. They both can distribute the graphics load between multiple graphics cards.

The SLI is NVIDIA‘s solution for multiple graphics card while the CrossFire is the solution for multiple graphics cards by AMD.

11. Video Driver Issue

The drivers that are being used in the GPUs account for the software functionality and capability of the GPU. Using outdated or faulty drivers can affect the working of your system.

However, having the latest drivers is not the solution to every problem. This means that latest drivers cannot guarantee a problem free environment. Sometimes having a new driver can become the reason for the droppage of your GPU’s usage.

If this happens, go back to the previously functional drivers. Make sure that you completely uninstall the previous drivers. You can do it by installing DDU. It is the uninstaller for drivers of the GPU.

Use this tool and revert back to the drivers that acted normally on your system.


GPU is an integral part of your computing and gaming experience so it is important that you look after it. Its health and life can be assessed by checking for its temperature and the usage.

In case the usage of your system drops to 0, know that the GPU is not working properly. To fix this issue, first understand the cause of your problem then move on to the solution. Once you diagnose the problem with your GPU, one of the above fixes will surely and hopefully treat the problem.


Is it fine if GPU usage is 0

GPU usage should not be 0. It means that the resources of the GPU are not being utilized. This results in an fps drop and stuttering in games and other programs that are GPU-dependent. This issue should be solved first hand.

Why does my GPU usage fluctuate?

GPU usage may go from 0 to 100 and vice versa. This may happen due to the faulty delivery of the CPU. This means that due to the CPUs inability to completely deliver to the GPU, its usage fluctuates. As it goes up and down the fps also drops. The problem here is the CPU.

How to force high GPU usage?

This can be done by going to the settings of your GPU system. For instance, in the NVIDIA’s GPU, you have to go to NVIDIA control panel on desktop and choose settings. There in the power usage setting, choose maximum power.

Low GPU usage in games is one of the most common problems that trouble many gamers worldwide. Low GPU usage directly translates to low performance or low FPS in games, because GPU is not operating at its maximum capacity as it is not fully utilized. To get the maximum performance out of your graphics card and in games, your GPU usage should be around 99% or even 100%. If you are getting less than this then you are suffering from low GPU usage problem, which ultimately means less FPS and lower performance in games.

There are many factors that can cause low GPU usage, depending upon the system configuration and drivers you have. It also means that there are both hardware and software factors involved in lower GPU utilization of your graphics card. So, here in this post, I am going to list all the causes and it fixes for low GPU usage. Let’s get started now!

How to check your CPU & GPU Usage

You can easily check your CPU and GPU usage by using a free graphics card monitoring and an overclocking utility called MSI Afterburner. Using its OSD or On Screen Display monitoring function, you can get all the GPU and CPU related information and game FPS in real-time at the corner of your screen while gaming. It can show your GPU usage, CPU usage, RAM usage, CPU & GPU temperature, Frame Rate or FPS and much more.


Below is the complete guide on how to monitor your GPU usage, CPU usage, and other parameters in real-time.

Low GPU Usage in Games [Causes & Solutions]

Here are the top software and hardware related problems for low GPU usage with their appropriate fix.

CPU Bottleneck

One of the main causes of low GPU usage is due to CPU bottleneck. It means that you have an under-powered CPU that is not able to keep up with your graphics card performance. For example, if you pair a GTX 1080 Ti graphics card with an Intel Pentium G4400 processor then you are bound to have a serious CPU bottleneck and your GPU will remain underutilized for most of the time.

If you have 100% CPU usage in games and low GPU usage i.e. (well below 99%) then you have a CPU bottleneck, and you need to get a better and powerful processor for your gaming PC. For an ideal situation, your CPU usage should remain in the 60% to 80% range (up to 90%), and GPU usage at 99% or 100%. You can check the CPU usage along with the GPU usage in real-time using the MSI Afterburner software, which I have already mentioned above. If you have a powerful CPU and still the GPU usage is also not at maximum then you have other issues, which you can check out below.


P.S. – A temporary workaround for this problem is to raise your game resolution to highest if you haven’t done it already. This will cause your GPU to work more and it will have much higher utilization than before.

Note:  Sometimes you may have to look for the individual core usage as not all games use all the CPU cores. It can be possible that you are getting high usage on two cores only, and others are just not used at all.

Video Driver Issue

Video drivers also contribute a lot to this low GPU usage problem. It is also important to note that the latest drivers are not always better, as I have experienced this many times with my graphics card in the latest games. So, if you have the latest graphics card drivers installed and getting low GPU usage then you can roll back to previous drivers, and see if the problem goes away or not. Also, if you have older drivers installed then you can install the latest ones and monitor the GPU usage.

Here I would also like to add that if a particular driver works best for your GPU then it is not certain that it will also deliver the best performance for other GPUs. For example, I get the best performance in games with Forceware 388.71 drivers on Windows 10 64-bit for my GeForce GTX 1050 Ti graphics card. If I install the latest drivers then I do notice lower performance and stuttering, even in the latest games. One another thing you should always keep in mind before installing video drivers, you have to completely uninstall previous drivers using DDU or Display Driver Uninstaller, which is the best video card driver uninstaller utility that removes every trace of the older video driver including its registry. DDU works with both Nvidia and AMD graphics cards

GPU Overheating

If the GPU of your graphics card is overheating then it may throttle down to lower GPU clock speeds, and it results in a major drop in FPS in games. The most common causes of GPU heating are:

Overclocking – If you have overclocked your graphics card beyond its limit, then most likely the GPU cooler is not able to keep up with the temperature. Eventually, the GPU will definitely get overheated and throttle down to lower clock speeds to avoid any kind of damage to itself. So, reduce or disable the overclock and keep the temperature under safe working levels, as specified by the GPU manufacturer.

Bad Contact / Thermal Paste – Improper contact between the GPU and heatsink also results in overheating of the GPU. Also, bad or worn out thermal paste does result in overheating too. So, here you have to take out the heatsink and apply good quality thermal paste, and then securely tighten the heatsink over the GPU.

Higher Case Temperature – If your case has bad airflow then you have higher case temperature and thus higher temperature of other components including graphics card. So, my advice here is to install at least one intake fan and one exhaust case fan to improve airflow. Good airflow will decrease the temperature of your graphics card and prevents it from overheating.

Check out:Guide to Decrease GPU temperature

GPU Fan Issue – Sometimes a faulty and damaged fan can also be a cause for GPU overheating. The only way to fix this issue to replace the graphics card fan with a new one.  You can check out the guide below on how to find a replacement fan for your graphics card model.

Check out:Graphics Card Fan Replacement Guide

Graphics Card VRM Overheating

VRM or Voltage Regulator Module is one of the most important parts of a graphics card. Its main job is to provide the right specified voltage to the GPU and VRAM. VRM mainly consists of MOSFETs, Capacitor, Inductor, and PWM controller. MOSFETs are the major component of a VRM and they heat up pretty quickly, and if they get overheated then they will not be able to provide sufficient power to the GPU, which can force it to throttle down, and thus may cause low GPU usage and lower frame rates. Sometimes, the contact between the VRM MOSFETs and the heatsink of the graphics card is not proper because of crappy thermal pads used in the manufacturing process. So, to fix this you can get good thermal pads of appropriate thickness and replace the older ones with them.

Game Related Issue

Some of the games are more dependent on the CPU due to their bad optimization. So, here GPU usage bound to be lower and you cannot do anything about it rather than installing the patches or fixes released by the game developer to fix this problem. You can upgrade to a much powerful CPU but if the issue is only with a couple of poorly optimized games then you don’t upgrade your processor for these crappy CPU intensive games.

Power Supply Issue

An underpowered PSU or a faulty 6-pin/8-pin PCIe connector can also contribute to this problem. This is because then the power supply will not be able to supply sufficient power to your graphics card and CPU, and due to this they will not operate at their maximum potential. So, make sure you have a good power supply for your gaming rig, and also check that all of its connectors are working properly. You can use a multi-meter to check the PSU connectors.

Power Management Settings

Windows Power Management Setting for PCI Express is one of the most common causes of low GPU usage, and this has been reported by many gamers. If this setting (Link State Power Management) is set to maximum power saving mode then it will cause the PCI Express interface to operate at lower clock speeds and cause PCI-E devices i.e. graphics card to under-perform. To turn off this setting in Windows 10 / 8 / 7, follow the steps mentioned below.

Step 1. Go to Control Panel->Power Options.

Step 2. Here click on Change plan settings to the plan that is selected here. Below you can see that the default selected plan is Balanced.


Step 3. Now click on Change advanced power settings.


Step 4. The Power Options window will open and here scroll down to expand PCI Express and then Link State Power Management. In the Settings drop-down box, select Off and click Ok to save the changes. You may also have to restart your computer to make sure the changes have been applied.


After this, your graphics card PCI-Express slot will operate at full speed and you may see higher GPU usage and performance in games. Some users have reported at least 10 FPS increase in games after turning OFF Link State Power Management setting in Power Options.

Moreover, Nvidia also has power management settings in their control panel that you can set to maximum performance if you are still having issues with low GPU usage. To set it to maximum performance, go to Nvidia control panel->manage 3d settings->power management mode->prefer maximum performance. This is shown in the image below.


Windows Updates

Yes, windows updates are quite notorious these days, especially if you are using the Windows 10 operating system. If you have noticed a sudden decrease in performance in games after a Windows update then most likely the culprit is the Windows update only. Here you can either roll back to the previous update or reinstall the Windows 10 OS again. You can also wait for the next update to see that if the problem has been fixed in the newest update or not, but my personal advice is to be rollback or clean install Windows if rollback fails. However, in some cases, updating Windows can fix this issue, especially when you have a very older version of Windows i.e. older than the graphics card itself.

P.S. – You can disable windows updates to keep this from happening again and again. Yes, it may pose a security risk but most of the users do have it disabled, especially the gamers.

SLI / CrossFire Issue

If you are running multiple graphics cards in Nvidia SLI or AMD CrossFire mode, then you may face this low GPU problem quite often. This can be due to faulty HB Bridge, driver issues, and it has also been seen that some games do not run well with SLI / CrossFire setup. So, here you can reseat your HB SLI Bridge or try getting a newer one that is offered by the Nvidia itself. You can also install the latest video drivers or roll back to previous video card drivers, or try disabling the SLI / CrossFire for the particular game. Make sure that you clean install the video driver by uninstalling the previous one using DDU (Display Driver Uninstaller)  utility. Moreover, you can also try switching from Rendering mode to Alternate Frame Rendering (AFR), which may help to maximize GPU usage.

Note: If you have a Pascal based graphics card then you might want to disable G-Sync in Nvidia control as it has been reported by many users that G-Sync is broken with Pascal graphics cards in SLI for some games and applications.

G-Sync / FreeSync + VSync Issue

G-Sync and FreeSync are adaptive or variable refresh rate technologies from Nvidia and AMD respectively to eliminate screen tearing and stuttering in games. It is possible that you can experience low GPU usage when G-Sync / FreeSync along with VSync is enabled or you have capped the FPS for that game using in-game settings or by using FPS limiter software. It is generally done because G-Sync / FreeSync does not work above the monitor’s refresh rate, and it is necessary to limit the maximum FPS below the refresh rate of the monitor if you are getting frame rates above monitor’s maximum refresh rate. This is because if you have a 75Hz monitor and a powerful graphics card that is generating more than 100 FPS in that game, then FPS limiter software or V-Sync will cause your graphics card to work less by limiting the maximum FPS to the monitor’s refresh rate or even lower than you have specified, and it does result in somewhat lower GPU utilization. However, when you disable V-Sync or remove the FPS cap, then your graphics card is going to spit out as many frames as possible, which will make your GPU usage highest. So, here if you are seeing low GPU utilization then you should not worry about it as it is very normal.

G-Sync along with SLI can cause low GPU usage due to driver and game compatibility issues. So, here you can either try out other drivers or you can disable either the G-Sync or SLI for the game to fix the issue. Some users have also reported success by uninstalling GeForce Experience with SLI+G-Sync for low GPU usage issues. Also, turn off the V-Sync if you have G-Sync / FreeSync enabled.

Bitcoin Virus / Malware

If you are playing a pirated version of the game that is infected with a Bitcoin virus or any other Malware, then these malicious programs can cause high CPU usage, and this will result in low GPU usage because the CPU is not able to cope up with the graphics card.  So, here scan your system with a good Antivirus and Ant-malware software and get rid of the virus or malware. For Anti-virus, I recommend ESET NOD32 Anti-virus and for Anti-Malware, Malwarebytes Anti-malware is the best you can get.

Disable HPET

High Precision Event Timer (HPET) is a hardware timer that is needed by Windows OS for some Multimedia related tasks. When enabled, this timer may cause low GPU usage and huge performance loss in games. You have to check your computer BIOS to see if this timer is supported by your system or is enabled by default or not. You can disable HPET to gain performance in games and also have your GPU to run to its maximum performance.

To disable it HPET in Windows, Go to command prompt and type in the following command.

bcdedit /deletevalue useplatformclock

To enable HPET again, use the following command in the command prompt.

bcdedit /set useplatformclock true

Note: If you are facing instability issues with Windows and other software after disabling HPET, then you might want to turn it ON again when you are not gaming.

Disable SMT [for AMD CPUs]

Sometimes disabling Simultaneous multithreading (SMT) in AMD systems may help some users to gain better performance and high GPU utilization, especially in older games. However, for modern games and normal working, you should enable it for the better overall performance of your computer.

How does it feel whenever your GPU drops to 0 while you’re enjoying your favorite PC games? It’s annoying, right? It is exactly the same way for everybody, and it is one of the most common problems many gamers all over the world experience.

A drop in GPU usage translates to low performance or what’s referred to as FPS in games. This is because the GPU is not working at maximum capacity. As a result, its functions are not fully utilized in order to serve your needs.

If you want the best performance out of your graphics card, GPU usage should stand at about 99% or a full-fledged 100%. Anything less than that can easily lead to a low GPU usage problem while running some graphics-intensive programs and games on your PC.

GPU Usage Drops to Zero: Common Causes and How to Fix Them

There are some popular problems associated with low GPU usage. Before we get into that, it’s best to examine what a GPU is and how it functions.

What is the GPU?

The Graphics Processing Unit (GPU) is designed to handle everything that is transferred from the PC internals to a connected display. It doesn’t matter whether you’re gaming, running a video editing program, or using a web browser, the GPU renders every functionality.

A GPU is the most powerful component inside the PC, with most of its capabilities coming from the VRAM. These memory modules let the unit quickly store and receive data without routing through the CPU to the RAM on the motherboard.

This is because the video RAM used by your graphics card is different from the RAM your PC relies on.

Causes of Low GPU Usage While Gaming

We have established that most issues with low GPU usage stem from heavy usage. The problem could be a software and hardware-related issue. If you are playing a really interesting game you’re immersed in and experience a hitch or stop, it may be due to one or a couple of the following:

• Video driver issue
• Bottleneck
• Graphics card VRM overheating
• GPU overheating
• Game-related issues
• Power supply issues
• SLI/CrossFire issue

Video Driver Issue

Video drivers also contribute to issues with GPU usage. You need to know that having the latest drivers isn’t always the best. Your graphics card might even suffer for it. If you have the latest graphics card drivers installed, it might still malfunction. When it does, it’s possible to roll back to previous drivers.

After rolling back, observe if things are back to normal. If they are not, use a new set alongside previously installed drivers.

Again, a particular driver might work best for your GPU but still not deliver the best performances for others. In fact, it might work perfectly with one while stuttering on other GPUs.

In addition, note that, before installing video drivers, you have to completely uninstall previous drivers using DDU.

DDUs work with both Nvidia and AMD graphics cards. They present the best video card driver uninstaller utility program that takes out every trace of the older video from the driver’s registry.


This is one of the major causes of low GPU usage. Bottleneck means that you have an under-powered CPU that can’t keep up with your graphics card performance.

Look at it this way: if you pair a GTX 1080 Ti graphics card with an Intel Pentium G4400 processor, the only result is a bottleneck. Your GPU remains underutilized for a long period of time.

Another way of explaining this concept is when you have a 100% CPU usage in games and low GPU usage. A CPU bottleneck results here, hence you’ll need a better processor to fit your gaming PC.

It’s okay to have your CPU usage within the 60 to 70% range, and a GPU usage at 99 to 100%. To check both, an MSI Afterburner software will come in handy. Bottlenecks are one of the reasons your GPU usage drops to 0 while gaming.

Graphics Card VRM Overheating

A VRM or Voltage Regulator Module is a vital component of a graphics card. One of its major functions is to provide the ideal specified voltage to the GPU and VRAM. The VRM is made up of several parts, including MOSFETs, Capacitor, Inductor, and PWM controller.

The MOSFETs stand out as the most vital part of a VRM. Perhaps that’s why they overheat rather quickly. Once they do, they will not be able to provide sufficient power to the GPU. In most cases, this leads to a forced throttle down, resulting in GPU usage drop.

The VRM MOSFETs might also have poor contact with the heatsink of the graphics card. This is mostly caused by an inadequate thermal pad used in the manufacturing process. If you want to fix this, use better thermal pads with the right thickness to replace the older ones.

GPU Overheating

If the GPU of your graphics card is overheating, throttling down to lower GPU clock speeds is inevitable. This will lead to a huge drop in FPS in games. Some of the reasons you may experience overheating in your GPU include the following:


This is a major part of gaming. Once you overclock on your graphics card beyond what it can take, the GPU cooler won’t be able to keep up with the temperature. As such, it will overheat and throttle down to lower clock speeds. This way, it doesn’t self-destruct.

What you can do is reduce or stop the overclock and keep the temperature under normal working levels specified by the brand.

Fan Issues:

With your computer getting so hot, a bad or faulty fan could be the problem. You should replace the bad graphics card fan with a new one. This is the only way to deal with this issue.

Higher Case Temperature:

This often happens with a bad airflow from the case. As such, a higher case temperature develops and affects many components. Your graphics card is not left out. To deal with this, install at least one intake fan and one exhaust case fan to improve airflow.

Good airflow is necessary to reduce the temperature of your graphics card and stops it from overheating.

Game-Related Issues

A lot of games depend on the CPU, especially if they have bad optimization. This ultimately leads to very low GPU usage. It’s worth noting that this can’t be fixed unless you install patches or fixes released by the game developers.

You can also upgrade to a higher-performance CPU. However, if the issues are caused by the games being poorly optimized, there’s no need to upgrade your processor.

Power Supply Issue

Having an underpowered PSU or a faulty 6-pin/8-pin PCIe connector contributes to GPU power drops. The power supply will fail to transmit enough power to your graphics card and CPU. As a result, both of them will have a hard time operating to their full capacity.

A good power supply, especially for your gaming system, is very important. Further, checks on all connectors often make the difference, especially if they’re not working well. A multi-meter will help you check the PSU connectors.

SLI/CrossFire Issue

This issue comes about when you have driver issues or a faulty HB Bridge. Also, some games don’t run as well with SLI/Crossfire setup. It’s possible to run multiple graphics cards on Nvidia SLI or AMD CrossFire Mode and still have a low GPU problem.

Your HB SLI Bridge can reset, or you can replace it with a new one. Another solution is to install the latest video drivers or roll back to previous video card drivers. Again, you can disable the SLI/CrossFire for that particular game.

Further, you can attempt to switch from Rendering Mode to Alternate Frame Rendering (AFR). This can help to maximize GPU usage and stop any GPU drops to 0mh/s.

Tips to Deal with GPU Usage Drops

Measure your GPU usage consistently:

One thing is clear: you can’t improve your GPU usage without measuring it. Just use a useful tool like Nvidia-SMI to take a snapshot of your usage. You could simply track its usage over time. If you’re a gamer, this could mean stopping your GPU 3D from dropping to 0%.

Let your GPU be the Bottleneck:

When the memory usage increases, the GPU usage drops down.


GPUs are getting all the more faster with different models to significantly improve efficiency. This article has shown that they won’t be without problems, especially if you love to game on your system. Your GPU doesn’t have to sit idle because of the mentioned causes in usage drops.

The problems can be fixed. Some of them require basic functions to adjust quickly. The most important thing is to squeeze out every bit of the 100% usage to enjoy your gameplay. Always remember to measure your GPU usage for effective and efficient performance.
