How to Fix Windows PC Is Using CPU Instead of GPU

A Windows PC using the CPU instead of the GPU for graphics-intensive tasks can lead to poor performance, low frame rates, high CPU usage, overheating, and lag in games or creative applications. This issue is especially common on systems with dedicated GPUs, such as NVIDIA or AMD graphics cards, where applications should offload rendering and processing to the GPU.

On Windows 11, apps may default to CPU-based rendering due to incorrect graphics settings, outdated drivers, power-saving configurations, or improper GPU selection. In laptops, hybrid graphics setups can also cause Windows to favor the integrated GPU or CPU instead of the dedicated GPU.

Fixing a Windows PC that uses the CPU instead of the GPU involves configuring graphics preferences, updating drivers, and ensuring the correct hardware is selected. The steps below explain how to resolve the issue and force apps to use the GPU properly.

How to Fix Windows PC Is Using CPU Instead of GPU

The methods in this section focus on correcting GPU selection, power settings, and driver-related issues. Apply the steps in order and test GPU usage after each method.

1. Verify That a Dedicated GPU Is Detected

Ensure Windows recognizes your GPU.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Go to the Performance tab.
3. Check if GPU appears in the list.
4. Select it and confirm usage details are shown.

If the GPU does not appear, driver or hardware issues may exist.

2. Set Preferred GPU for Apps in Windows 11

Windows allows per-app GPU selection.

1. Open Settings.
2. Go to System.
3. Select Display.
4. Click Graphics.
5. Add the affected app if not listed.
6. Click Options.
7. Select High performance.
8. Save changes.

This forces the app to use the dedicated GPU.

3. Update GPU Drivers

Outdated drivers can prevent GPU usage.

1. Press Windows + X and open Device Manager.
2. Expand Display adapters.
3. Right-click your GPU.
4. Select Update driver.
5. Choose Search automatically for drivers.
6. Restart the computer after updating.

Updated drivers improve GPU compatibility.

4. Configure GPU Settings in NVIDIA or AMD Control Panel

Vendor control panels override Windows settings.

1. Open NVIDIA Control Panel or AMD Software.
2. Go to Manage 3D settings or equivalent.
3. Set Preferred graphics processor to the dedicated GPU.
4. Apply changes.

This ensures apps use the correct GPU.

5. Disable Power-Saving Mode

Power plans may limit GPU usage.

1. Open Settings.
2. Go to System.
3. Select Power & battery.
4. Set Power mode to Best performance.
5. Plug in the laptop if applicable.

Power saving modes prioritize CPU usage.

6. Check BIOS or UEFI GPU Settings

BIOS settings may restrict GPU usage.

1. Restart the computer.
2. Enter BIOS or UEFI settings.
3. Look for Graphics or Display options.
4. Ensure dedicated GPU or hybrid graphics is enabled.
5. Save and exit.

Incorrect BIOS settings can disable GPU acceleration.

7. Disable Integrated Graphics (Advanced)

This forces Windows to use the dedicated GPU.

1. Open Device Manager.
2. Expand Display adapters.
3. Right-click the integrated GPU.
4. Select Disable device.
5. Restart the computer.

Use this method carefully, especially on laptops.

8. Update Windows 11

System bugs may affect GPU usage.

1. Open Settings.
2. Go to Windows Update.
3. Install all available updates.
4. Restart the system.

Windows updates often improve hardware handling.

9. Monitor GPU Usage During Workloads

Confirm that fixes are working.

1. Open Task Manager.
2. Go to Performance.
3. Run a GPU-intensive app.
4. Check GPU usage in real time.

This verifies whether the GPU is being used.

10. Reinstall GPU Drivers as a Last Resort

Corrupted drivers can block GPU acceleration.

1. Uninstall GPU drivers using Device Manager or vendor tools.
2. Restart the computer.
3. Download and install the latest drivers from the GPU manufacturer.
4. Restart and test again.

Clean driver installation resolves persistent issues.

Final Thoughts

A Windows PC using the CPU instead of the GPU is usually caused by incorrect graphics settings, outdated drivers, or power-saving configurations rather than faulty hardware. In most cases, setting the preferred GPU for apps and updating drivers resolves the issue quickly.
