Why Is My GPU Usage Low? Solved for Every Cause (2026 Guide)

Why Is My GPU Usage Low? This is one of the most searched questions in PC gaming right now, and one of the most poorly answered. While building this site I went through hundreds of forum threads on Reddit, Tom’s Hardware, PC Gamer and Quora. Same story everywhere. People with RTX 3070s showing 45% GPU usage. RTX 4080s stuck at 60%. Good hardware. Bad performance. No clear explanation.

One person on Tom’s Hardware wrote: “I have a GTX 1080 Ti paired with a Ryzen 5 2600 and my GPU usage doesn’t go above 65% in any game. I’ve reinstalled Windows 8, 10, and 11. Nothing works.”

Another on the PC Gamer forums posted: “My RTX 3060 Ti sits at 40% GPU usage and gives me 60 FPS. My friend has the same specs and gets 99% GPU usage and 20 to 40 FPS more than me.”

And one of the most frustrating cases found recently. A user on Steam forums with an Intel Core Ultra 9 285K and RTX 5080 wrote: “My GPU usage almost never hits 99%. Mostly it’s around 20 to 70% when moving. I’ve tried literally everything, every setting, DX12, DX11, DLSS, FSR, VSync on and off. Nothing helps.” Even with a top-tier 2026 build worth thousands of dollars, the problem still appeared.

These are real people, real problems. And the reason I built mypcbottleneck.com is exactly because of situations like this, where someone has good hardware, something is going wrong, and nobody is giving them a clear, simple answer.

So today I am going to give you that answer. Every single cause of low GPU usage. Every single fix. In the simplest words I know.

Let us start.

Before we fix anything, let us make sure we understand the number we are looking at.

Your GPU usage percentage is simply how much of your graphics card’s power is being used right now.

Think of your GPU like a very fast worker at a factory. His job is to build the pictures, called frames, that appear on your screen. When you are gaming, he should be running at full speed, 95% to 100%, building frames as fast as he possibly can.

If his usage is 95 to 100%: He is working hard. Good. Your graphics card is the thing limiting your FPS. The only way to get more frames is a faster GPU.

If his usage is 50 to 70%: He is going half speed. Something is stopping him from working harder. You are losing performance you already paid for.

If his usage is below 50%: He is barely doing anything. Something is seriously wrong.

The goal is always to be as close to 100% as possible while gaming. That means you are squeezing every drop of performance out of your graphics card.

Now why would your GPU be running slow when it should be running fast? Let me show you every reason.

I am not going to give you a generic list. Every reason below comes from real complaints found across forums, Reddit threads, and support pages, with the actual fix that worked for real people. Go through them one by one. Your answer is in here somewhere.

“I have the same GPU as my friend but he gets way more FPS. Why?”

The answer is almost always the same thing: your CPU.

Here is how a game actually works. Before your GPU can draw a single frame, your CPU has to do a lot of work first. It figures out where all the characters are. It calculates the physics, how bullets fly, how water moves. It handles the AI, what every enemy is thinking. It prepares a list of instructions called draw calls and sends them to the GPU.

Only after the CPU finishes all of that can the GPU start drawing.

Imagine your GPU is a racing car driver sitting in his car, ready to go 200 miles per hour. But before he can start his lap, he has to wait for his manager, the CPU, to finish writing his instructions on a piece of paper. If the manager is slow, the driver just sits there waiting. He is not at 100% because he literally cannot start yet.

This is what a CPU bottleneck looks like. Your GPU is bored, sitting idle, waiting for the CPU to catch up.

Here is something most guides miss. Task Manager can actually lie to you about this. A user on Steam forums with an i7-12700K noticed his overall CPU usage showing only 20 to 50% while his GPU sat low. But when he looked at individual cores in Task Manager, Core 1 was pinned at 100%. That single bottlenecked core was choking the entire game. Overall CPU percentage does not tell the full story. Individual core usage does.

To properly check this: open Task Manager, go to Performance, click CPU, right-click the graph and select Logical Processors view. This shows every core individually. If even one core is hitting 100% while your GPU is below 70%, you have a CPU bottleneck regardless of what the overall percentage shows.

Want to know exactly how bad the mismatch is between your CPU and GPU? Use our PC Bottleneck Calculator to get the exact percentage and find out which upgrade will help the most.

Step 1 — Enable XMP or EXPO in BIOS (FREE, do this first)

This is the single most underrated fix in PC gaming. When you buy RAM rated at 3600MHz or 6000MHz, it does not run at that speed until you tell your motherboard to enable it. Most systems default to 2133MHz regardless of what the sticker says.

Slower RAM means your CPU gets data slower, which means it takes longer to prepare frames, which means your GPU waits longer, which shows up as low GPU usage.

How to enable XMP/EXPO:

1. Restart your PC
2. Press Delete or F2 during startup to enter BIOS
3. Look for XMP on Intel boards or EXPO on AMD boards
4. Enable it
5. Save and exit

People on forums have reported recovering 20 FPS in Cyberpunk 2077 just from this one BIOS toggle, no new hardware, no money spent. Not sure how fast your CPU actually is? Check where your CPU ranks on Tom’s Hardware to see if it is the real bottleneck in your system.

Step 2 — Raise your resolution or graphics settings

This sounds backwards but it works. At low resolution and low settings, your GPU finishes each frame so fast it has to sit and wait for the CPU to prepare the next one. Turning up the graphics gives the GPU more work per frame, meaning it spends less time idle.

Try going from 1080p to 1440p, or increase settings from Medium to High. If your GPU usage goes up, you just confirmed a CPU bottleneck and found a free workaround at the same time.

Step 3 — Close background programs

Discord, Chrome, Spotify, RGB software, Windows Update. All of these steal CPU time your game needs. Before gaming, close everything you are not using. Open Task Manager and end any process eating CPU in the background.

Step 4 — Enable Hardware Accelerated GPU Scheduling (HAGS)

1. Click Start then Settings
2. Go to System, then Display, then Graphics
3. Click Default graphics settings
4. Turn on Hardware Accelerated GPU Scheduling
5. Restart your PC

This reduces how much the CPU has to manage GPU memory and often improves GPU usage in bottlenecked systems.

Step 5 — Upgrade your CPU (last resort)

If nothing above works and your CPU is 4 or more years older than your GPU, you need a newer processor. A Ryzen 5 2600 paired with an RTX 3060 Ti is a serious mismatch in 2026. Upgrading to a Ryzen 5 7600 or Core i5-13600K can completely transform your gaming experience without touching the GPU.

“My GPU usage is only 40% but my game runs fine. What is happening?”

This is the most common innocent cause of low GPU usage. And in most cases it is not actually a problem at all.

VSync locks your FPS to match your monitor’s refresh rate. If you have a 60Hz monitor, VSync locks your game at 60 FPS. If your GPU can produce 200 FPS but VSync caps it at 60, your GPU only needs about 30% of its power. So it shows 30% usage. But your game runs fine because 60 FPS is all your monitor can display anyway.

A user on PC Gamer forums was complaining about 30 to 50% GPU usage. Someone in the thread asked: “Do you have power saving settings enabled?” He did. He turned them off, removed the FPS cap, and his GPU jumped straight to 99%.

Places where FPS caps hide:

VSync in the game settings. VSync in NVIDIA Control Panel or AMD Adrenalin. In-game FPS limiter in the settings menu. RivaTuner Statistics Server if you have MSI Afterburner installed. NVIDIA Max Frame Rate setting. G-Sync or FreeSync, which cap FPS at the monitor’s maximum refresh rate.

How to fix it:

Step 1: Open game settings, find VSync or Max FPS, turn VSync off and remove any FPS cap.

Step 2: Open NVIDIA Control Panel by right-clicking the desktop. Go to Manage 3D Settings, then Program Settings, find your game, set Vertical Sync to Off and Max Frame Rate to Off.

For AMD: Open Adrenalin, go to Gaming, select your game, and turn off Radeon Enhanced Sync and FRTC.

Step 3: If you have MSI Afterburner installed, open RivaTuner Statistics Server and make sure the framerate limit is set to 0.

If GPU usage jumps to 95% or higher after this, VSync was your only problem. You can re-enable it if you want to stop screen tearing, just know it will bring GPU usage back down, which is perfectly normal.

“Why is my GPU at 10 to 15% usage even though it’s a dedicated card? I’m on a laptop.”

Most laptops and some desktops have two GPUs.

The first is integrated graphics, built into the CPU, for example Intel UHD or AMD Radeon. It is weak and uses very little power. The second is your dedicated graphics card, your actual gaming GPU. It is powerful.

Windows sometimes sends your game to the integrated chip to save battery, while your dedicated GPU sits at 5% doing nothing.

A user on a gaming forum wrote: “I play Fortnite and get 25% CPU usage, 40% integrated graphics usage, 15% dedicated GPU usage, and still get bad frames.” Their expensive GPU was barely being used because Windows routed the game to the wrong chip entirely.

How to fix it on Windows 10 and 11:

Step 1: Right-click the desktop, go to Display settings, scroll down and click Graphics.

Step 2: Click Add an app, browse to your game’s .exe file, usually in your Steam or Epic Games folder.

Step 3: Click the game in the list, click Options, select High performance, and save.

Step 4: Also set it in your driver software.

For NVIDIA:

1. Open NVIDIA Control Panel
2. Go to Manage 3D Settings, then Program Settings
3. Find your game and set the preferred graphics processor to High-performance NVIDIA processor
4. Click Apply

For AMD:

1. Open AMD Adrenalin
2. Go to Gaming and add your game
3. Set Graphics Profile to High Performance

Laptop users: Always plug your laptop in when gaming. On battery, most laptops throttle or completely disable the dedicated GPU to save power. This is by design, not a fault with your hardware.

“GPU usage randomly drops from 99% to 40% for a second then goes back up.”

Random unexplained dips, not consistent low usage but sudden brief drops, are almost always caused by corrupted or outdated GPU drivers.

GPU drivers are the software that lets Windows talk to your graphics card. When they are old, corrupted, or installed on top of a previous broken version, they cause erratic behavior, random usage drops, poor performance, and visual glitches.

In 2026, NVIDIA and AMD both release regular driver updates. Some have delivered 10 to 15% performance improvements in specific games. Running old drivers does not just miss bug fixes. It can actively hurt your GPU usage and FPS.

A user on Tom’s Hardware tried every fix imaginable, reinstalling Windows, changing power settings, verifying game files. Nothing worked. A clean DDU driver reinstall solved it in 15 minutes.

How to do a proper clean driver install:

Step 1: Download DDU (Display Driver Uninstaller) from guru3d.com. This properly removes every trace of old drivers. The normal Windows uninstall leaves residue behind that causes problems.

Step 2: Boot into Safe Mode. Press Windows and R together, type msconfig, press Enter, click the Boot tab, check Safe boot, click OK, and restart.

Step 3: In Safe Mode, run DDU, select your GPU type, and click Clean and Restart.

Step 4: After the restart, download fresh drivers from the official sites.

For NVIDIA: nvidia.com/drivers

For AMD: amd.com/support

Choose Custom Installation and check Perform a clean installation.

Step 5: Restart and test your game.

This takes 15 minutes and has solved GPU usage problems that seemed impossible for hundreds of people across forums.

“My GPU usage drops and FPS crashes every 30 seconds, then comes back.”

This looks like a random performance problem but it has one very specific cause: thermal throttling.

When your GPU gets too hot, it automatically slows itself down to prevent damage. Usage drops. FPS crashes. Then it cools slightly and comes back. Like someone turning a faucet on and off repeatedly.

A user on Tom’s Hardware described exactly this. FPS dropping from 200 to 30 every 20 to 30 seconds, recovering, then dropping again. Their GPU temperatures looked fine at first glance, but only because the throttling was keeping the card cool by slowing it down just before it overheated. Classic thermal throttle loop.

GPU throttling thresholds in 2026:

GPU Brand	Throttling Starts Around
NVIDIA RTX 30, 40, 50 series	83 to 87°C
AMD RX 6000, 7000, 9000 series	90 to 95°C

Check your temperature by opening GPU-Z from TechPowerUp, clicking the Sensors tab, and watching GPU Temperature while gaming.

For a full breakdown of what GPU temperatures are safe, normal, and dangerous in 2026, read our GPU Temperature Range guide.

You can also learn more about how thermal throttling specifically affects gaming performance in our Thermal Throttling guide.

How to fix thermal throttling:

Step 1: Clean your GPU. Dust is the number one cause. A can of compressed air blown through the GPU fans drops temperatures 5 to 15°C instantly for most people. Do this first, every time.

Step 2: Improve case airflow. At minimum, one intake fan at the front and one exhaust fan at the rear. Hot air needs a clear path out of the case.

Step 3: Adjust fan curve in MSI Afterburner. Create a more aggressive curve that spins fans faster at higher temperatures before throttling ever kicks in.

Step 4: Repaste the GPU (advanced). If your card is 3 or more years old, the thermal paste may have dried and cracked. Replacing it drops temperatures 15 to 20°C. This requires disassembling the GPU and should only be done if you are comfortable doing so.

“I have 16GB RAM but GPU usage is still low. My friend with 16GB is fine. Same CPU.”

This is something almost nobody explains clearly. It is not just how much RAM you have. It is how it is installed.

RAM works best with two sticks in the correct slots, which is called dual channel. One stick, called single channel, cuts your memory bandwidth roughly in half.

Why does this affect GPU usage? Your CPU needs fast memory access to prepare draw calls for the GPU. Slow memory means the CPU takes longer to do its work, which means the GPU waits longer, which shows up as low GPU usage.

A user on cgdirector.com with an i5-11400F, RTX 2060 Super, and a single 16GB stick was getting 40% GPU usage and 60 FPS on a 165Hz monitor. The first question asked was whether their RAM was in single channel. It was. Installing a matching second stick brought immediate improvement.

In 2026, with DDR5 becoming mainstream, single-channel DDR5 is even more punishing because the bandwidth gap between single and dual channel is larger than ever before.

You can read more about this in our detailed RAM Bottleneck guide.

How to check:

Option 1: Open CPU-Z from cpuid.com, go to the Memory tab, and look at Channels. It must say Dual, not Single.

Option 2: Open Task Manager, go to Performance, then Memory, and check if the speed shown matches your RAM’s rated speed.

How to fix it:

Step 1: Open your PC case and check how many sticks are installed and which slots they are in.

Step 2: If you have one stick, buy a matching second stick and install it. Check your motherboard manual for the correct dual-channel slots, usually labeled A2 and B2.

Step 3: If you have two sticks in adjacent slots, move them to the correct alternating slots. Wrong placement defeats dual channel even with two sticks installed.

Step 4: After moving the RAM, go into BIOS and enable XMP or EXPO to run at the rated speed.

“My GPU usage is 99% in some games and 50% in others. Why?”

Some games are simply much harder on the CPU than others. This is not a problem with your PC. It is how the game was built.

Games with huge open worlds, hundreds of players, complex AI, and real-time physics are extremely CPU-heavy. At 1080p, these games push the CPU so hard that even a fast modern processor struggles to keep the GPU fully fed with work.

Games that commonly cause CPU-limited low GPU usage in 2026:

Warzone, with its massive maps, hundreds of players, and heavy physics. Cyberpunk 2077, with its dense city and thousands of AI characters. Cities Skylines 2, which is simulation-heavy and notoriously CPU demanding. Microsoft Flight Simulator, with real-time weather and global terrain streaming. Escape from Tarkov, which has a poorly optimized engine. GTA V Online, where server-side calculations add extra CPU load on top of everything else.

Meanwhile Valorant, CS2, and Rainbow Six Siege are GPU-limited by design because they target extremely high frame rates. Your GPU will always be well utilized in these games.

Check the GPU performance hierarchy on Tom’s Hardware to understand what FPS your card should realistically hit in CPU-heavy versus GPU-heavy titles.

What you can do:

Change your resolution. Moving from 1080p to 1440p or 4K shifts more work to the GPU and less to the CPU. GPU usage goes up and frame pacing often improves, even if absolute FPS drops slightly.

Lower CPU-specific settings, not GPU settings. View Distance, NPC Density, Physics Quality, and Shadow Distance are all CPU-bound. Lowering these specifically helps. Texture quality, reflections, and anti-aliasing are GPU-bound, so lowering those in a CPU-bottlenecked game does absolutely nothing useful.

Consider a CPU upgrade. If you play CPU-heavy games regularly and your processor is 3 to 4 generations old, upgrading is the correct answer. Read our how to fix bottlenecks guide for every option from free fixes to hardware upgrades.

“My GPU usage was fine yesterday and now it’s low for no reason. Nothing changed.”

This one tricks people because it can change without them doing anything at all. Windows updates silently reset power settings. Installing new software changes them. Unplugging a laptop changes them automatically.

When Windows is in Balanced or Power Saver mode, it deliberately limits how fast your CPU and GPU run. The CPU drops its clock speed. The GPU holds back its boost clock. The result looks like low GPU usage and low FPS but nothing is actually broken. Windows is just being efficient.

In 2026 this is more relevant than ever. Windows 11 has more aggressive power management than Windows 10, and some NVIDIA and AMD driver updates silently reset GPU power settings after installation.

A user on PC Gamer forums had exactly this problem. Someone replied: “Go into Nvidia Control Panel, change Power Management to Prefer Maximum Performance. Also check Windows power settings. Sometimes GPU software includes performance settings that affect framerate pretty substantially.” That was the entire fix.

How to fix in 3 minutes:

For the Windows power plan:

1. Press Windows and R together, type powercfg.cpl, and press Enter
2. Select High Performance. If you cannot see it, click Show additional plans.
3. Click Change plan settings, then Change advanced power settings, find Processor power management, and set Minimum processor state to 100%

For NVIDIA:

1. Right-click the desktop and open NVIDIA Control Panel
2. Go to Manage 3D Settings, then Global Settings
3. Find Power management mode and set it to Prefer maximum performance
4. Click Apply

For AMD:

1. Open AMD Adrenalin
2. Go to Performance, then Tuning
3. Set Power Tuning to Manual and move the slider to +0% or higher
4. Under Global Graphics, make sure performance mode is not set to power saving

Many people see GPU usage jump from 60% to 95% or higher from this change alone.

Before doing any of the above, run these four tests in order. Stop the moment you find your answer.

No need to worry about this one.

If your GPU is sitting at 50% but you are hitting your target frame rate perfectly, say 60 FPS on a 60Hz monitor, that is not a problem. Your GPU is so powerful it does not need to work hard to give you the FPS you want.

Low GPU usage is only a problem when it comes with FPS you are not satisfied with. Low usage combined with bad performance means something is wrong. Low usage combined with perfectly smooth gameplay means you have a powerful card and an easy game. Enjoy it.

If your GPU usage looks fine but FPS is still dropping, that is a different problem. We covered every cause in our complete low FPS guide.

Reading this entire guide is helpful. But the fastest way to know exactly what is happening with your specific CPU and GPU is to use a dedicated tool.

Our PC Bottleneck Calculator was built for exactly this situation. Enter your CPU and GPU model and within seconds it tells you what percentage bottleneck you have, which component is limiting which, whether it is a CPU bottleneck, GPU bottleneck, or a balanced system, the most cost-effective upgrade for your specific build, and how much FPS improvement you can realistically expect.

It is free. It takes 30 seconds. And it will tell you more accurately than any guess whether spending money on a new CPU or GPU will actually improve your situation.

Your GPU usage should be 95 to 100% while gaming. If it is lower and your FPS is not where you want it, work through this checklist in order:

1. ✅ Enable XMP or EXPO in BIOS — free, 5 minutes, up to 20% FPS boost on Ryzen
2. ✅ Turn off VSync and FPS caps — check game settings, NVIDIA or AMD control panel, and RivaTuner
3. ✅ Set the correct GPU in Windows Settings — critical for laptops and pre-built systems
4. ✅ Clean GPU driver reinstall with DDU — removes corruption from old driver installations
5. ✅ Check GPU temperatures — above 85°C means thermal throttling is happening
6. ✅ Check RAM channels — single channel halves your memory bandwidth
7. ✅ Switch to High Performance power plan — Windows may be quietly holding back your GPU
8. ✅ Check individual CPU core usage — one maxed core is enough to bottleneck an entire game

In most cases reported across forums, the first three fixes alone solve the problem. Most of them are completely free. Most take under five minutes.

Your hardware is not broken. You just need to let it breathe.

Low GPU usage is one of those problems that looks complicated but almost never is. In most cases it comes down to one of eight things, and seven of them cost absolutely nothing to fix.

Before you post on a forum, before you start shopping for new hardware, go through the checklist one step at a time. Start with XMP. Check VSync. Verify the correct GPU is selected. Clean install your drivers. Check temperatures. These five steps alone fix the problem for the majority of people.

If you go through everything and still are not sure whether your CPU and GPU are properly matched for each other, use our free PC Bottleneck Calculator. Type in your specs and it tells you the truth in thirty seconds.

Your hardware is capable of more than it is giving you right now. This article just showed you how to unlock it.
