How to Check GPU Usage and What the Numbers Mean
How to check GPU usage takes about ten seconds: press Ctrl + Shift + Esc, open the Performance tab, and click GPU. The harder part is knowing what the number means. High usage in a game is usually a good sign, while low usage can reveal a bottleneck that’s holding your FPS back. This guide shows you every way to check it, what normal looks like, and what to do when the reading looks wrong.
How to Check GPU Usage in Task Manager (Windows 11 and 10)
Task Manager is already on your PC, so start here.
- Press Ctrl + Shift + Esc to open Task Manager. (If you see a tiny window, click More details.)
- Click the Performance tab.
- Choose GPU in the left list.
- Read the main graph, which shows live usage as a percentage. Below it you’ll see dedicated GPU memory (VRAM), shared GPU memory, and the driver version.
On a laptop with both a dedicated and an integrated graphics chip, you may see two entries, GPU 0 and GPU 1. The name shown under each tells you which is which. Click the one named after your NVIDIA or AMD card to see your gaming GPU. bravecollective
See which app is using the GPU
- Open the Processes tab.
- Right-click the column header and tick GPU and GPU engine.
- Click the GPU header to sort the list. Sorting by GPU shows which program is demanding the most, and you can end it from the same screen. guidingtech
A tip most guides skip: pick the right engine
Task Manager breaks GPU work into separate “engines,” such as 3D, Copy, Video Encode, and Video Decode. The big graph often shows only one of them, usually 3D. That means:
- A game will show strongly on 3D.
- Video editing or streaming may show on Video Encode.
- AI and compute tasks may show on Compute or Cuda.
If your usage looks oddly low, click the small dropdown above any graph and switch it to the engine your program uses. This catches many “my GPU isn’t being used” mistakes.
How to Check GPU Usage in Games
Task Manager works, but alt-tabbing out of a game can change the reading. An overlay shows live numbers while you play.
Xbox Game Bar (built into Windows)
- Press Windows + G while in a game.
- Open the Performance widget (find it in the widget menu if it isn’t showing).
- Look at the GPU section for usage and memory. You can pin the widget to keep it visible.
NVIDIA app overlay
If you have an NVIDIA card, open the in-game overlay (the default shortcut is Alt + Z) and turn on the performance or statistics view. Menu names change between versions, so look for the performance panel.
AMD Software: Adrenalin Edition
On an AMD card, open the Adrenalin software, go to the performance section, and enable the metrics overlay. It shows GPU usage, clock speed, temperature, and FPS.
NVIDIA command line
For a quick text readout, open Command Prompt and type nvidia-smi. To refresh it every second, use nvidia-smi -l 1.
MSI Afterburner and HWiNFO
For the most detail, including per-core CPU usage next to your GPU, use MSI Afterburner with its on-screen display, or HWiNFO64. Putting CPU and GPU readings side by side is the best way to spot a bottleneck.
What is Normal GPU Usage?
It depends on what you’re doing.
| Situation | Normal GPU usage | What it means |
|---|---|---|
| Idle on the desktop | About 0 to 10% | Healthy |
| Browsing, watching video | About 5 to 30% | Healthy |
| Gaming at uncapped FPS | Often 90 to 100% | Your GPU is doing its job |
| Gaming with an FPS cap or V-Sync | Lower, and can vary | Normal, because the GPU isn’t being pushed to its limit |
| Rendering, editing, AI tasks | High, often near 100% | Normal for heavy work |
| Idle but high usage | Over about 20 to 30% for long periods | Worth investigating |
These ranges are rough guides, since they shift with the card, resolution, and game. High usage is expected in demanding games and video editing, but unusually high usage while idle or doing simple tasks can signal a problem. guidingtech
A common surprise: 100% GPU usage in a game isn’t a problem. It means your graphics card is fully working, which is usually exactly what you want. It’s a warning sign only if you also see overheating, crashes, or stutter.
Why Is My GPU Usage Low?
Low GPU usage while gaming, with FPS lower than you’d expect, usually means something else is holding the GPU back. Check these causes in order.
1. A CPU bottleneck
If your processor can’t prepare frames fast enough, the GPU waits. To test it, open Task Manager’s CPU view, or use HWiNFO or MSI Afterburner, and watch your cores while playing. If one or two cores sit near 100% while the GPU has room to spare, your CPU is the limit. Our guides on what a PC bottleneck is and the GPU bottleneck explain this in depth, and you can run our free bottleneck calculator for a quick estimate.
2. An FPS cap, V-Sync, or VRR
A frame limit tells the GPU to stop working once it hits the target. That’s normal, but if you didn’t set one, check your game settings and graphics driver. What Is V-Sync? and What Is VRR? explain how these settings affect your frame rate.
3. DLSS or lower resolution
Upscaling reduces the pixel load, so your GPU usage drops and your CPU may become the limit. See What Is DLSS? for how that works.
4. The game is using the wrong GPU
On laptops and some desktops, a game can run on the integrated graphics chip by mistake. Open Settings > System > Display > Graphics, add the game, and set it to High performance. You can control which GPU a game uses from Windows 11’s Settings app. yahoo
5. Memory or storage limits
Too little RAM, slow storage, or a nearly full drive can cause stutter and uneven GPU usage. See our RAM bottleneck guide and why your PC is so slow.
6. An old or faulty driver
Outdated drivers can cause poor performance in new games. Follow our graphics driver update guide.
Why Is My GPU Usage High When Idle?
If your GPU is busy while you’re doing nothing, work through this list:
- Find the culprit. In Task Manager, sort the Processes tab by GPU and look for an unexpected app.
- Close background apps. Wallpaper engines, screen recorders, and extra browser tabs can all use the GPU.
- Turn off browser hardware acceleration temporarily to see if usage drops.
- Update your graphics driver and Windows.
- Run a malware scan. Viruses and other malware can cause high GPU usage when Task Manager doesn’t point to a clear cause. guidingtech
- Check your display settings. Multiple monitors or a very high refresh rate can raise idle usage a little.
If the readings are strange and you suspect the card itself, check temperatures with HWiNFO64 too, because an overheating GPU can behave oddly.
How to read your results: a quick guide
- GPU near 100%, FPS good: everything is working as intended.
- GPU well below 90%, CPU core near 100%: a CPU bottleneck. A faster processor or lower CPU-heavy settings will help.
- GPU low and CPU low, FPS capped: you’ve probably set a frame cap, V-Sync, or VRR limit.
- GPU high, FPS low: the game is too demanding for your card. Lower settings, use DLSS, or upgrade.
- GPU high at idle: hunt for a background process or malware.
Frequently asked questions
How do I check GPU usage on Windows 11?
Press Ctrl + Shift + Esc, open the Performance tab, and click GPU. For a live reading while you play, use the Xbox Game Bar (Windows + G) or your graphics card’s overlay.
What is a good GPU usage while gaming?
Roughly 90 to 100% when your frame rate isn’t capped. That means your GPU is being fully used.
Is 100% GPU usage bad?
Not on its own. In a game it’s normal. It’s only a worry if your GPU is also overheating, the game stutters, or the system crashes.
Why is my GPU usage so low in games?
The most common cause is a CPU bottleneck. Other causes include an FPS cap or V-Sync, the wrong GPU being used, or heavy upscaling.
Why does Task Manager show 0% GPU usage while I’m gaming?
The graph may be showing the wrong engine, or the game is running on your integrated GPU. Switch the graph to the 3D engine and check the Graphics settings.
How do I check GPU usage on a laptop?
Use Task Manager and pick the dedicated GPU (such as your NVIDIA or AMD card) from the list, not the integrated one. Set games to High performance in Windows graphics settings.
Can I check GPU usage without Task Manager?
Yes. Use the Xbox Game Bar, NVIDIA or AMD overlays, MSI Afterburner, HWiNFO, or nvidia-smi on NVIDIA cards.
Does high GPU usage damage the card?
No, not by itself. GPUs are designed to run at full load. Poor cooling is the real risk, so keep temperatures in check.
Why is my GPU usage high with nothing running?
A background app, browser acceleration, a driver issue, or malware. Sort Task Manager by GPU to see what’s using it.
Does lowering resolution reduce GPU usage?
Yes. Fewer pixels means less work for the GPU, which is also how upscaling like DLSS raises FPS.
Should GPU usage match CPU usage?
No. They measure different things, and in games one is usually higher than the other. What matters is which one is the limit.
Conclusion
How to check GPU usage is easy: Task Manager shows it in seconds, and an overlay like the Game Bar, the NVIDIA or AMD tools, or MSI Afterburner shows it live while you play. What matters is the context. A GPU near 100% in a game is healthy, a GPU well below that with a busy CPU points to a bottleneck, and a busy GPU at idle means something is running that shouldn’t be.
Once you know your reading, you can decide what to fix. If you suspect a bottleneck, use our free bottleneck calculator and read our guide to GPU bottlenecks. If you’re seeing screen problems alongside odd usage, see our monitor flickering guide.
