How to Set the Default GPU in Windows 10

This guide shows you how to set a default GPU in Windows 10, a useful skill to learn if you use resource-intensive apps on your Windows laptop.

Before we begin, let’s first distinguish the two types of GPUs. The GPU that comes with your CPU is called the integrated GPU. It shares the same resources as your computer, as it is integrated with the motherboard. Meanwhile, a dedicated GPU is a separate component that you will need to purchase. The dedicated GPU is intended for more high-performance tasks, such as video editing or gaming. To simplify their distinctions:

• Integrated GPUs are best suited for lightweight applications.
• Dedicated GPUs are ideal for more intensive tasks.

How to check your installed GPU

There are two ways to check which GPU is currently installed on your system:

Option 1: Using Device Manager

1. Search for “Device Manager” in the Start search button. In older Windows versions, you can go to Control Panel > Device Manager.
2. Look for Display adapters and click the dropdown arrow to see the list of GPUs installed on your system. Two entries indicate you have an integrated GPU and a dedicated GPU. If you only see one entry, it is likely an integrated graphics card, except in desktops without integrated graphics.

Option 2: Using Task Manager

1. Open Task Manager. The simplest way to do this is by simultaneously pressing Ctrl + Alt + Del and clicking on Task Manager.
2. Navigate to the Performance tab and look for the GPU section to determine which one is currently active.

Step-by-step guide on how to set preferred GPU on Windows 10 laptop

Method 1: Using Windows Graphics settings (Recommended)

1. Open Settings and go to System > Display.
2. Scroll down and click on Graphics settings.
3. Under Choose an app to set preference, select either:
   1. Desktop app (for installed programs) and click Browse to find the .exe file
   2. Microsoft Store app (for Windows Store apps) and select the app from the dropdown.
4. Once added, click on the application and select Options.
5. Choose one of the following options:
   1. Let Windows decide (default setting)
   2. Power saving (uses integrated GPU)
   3. High performance (uses dedicated GPU)
6. Click Save, then restart the application for the changes to take effect.

Method 2: Using NVIDIA control panel (For NVIDIA GPUs)

1. Right-click on the desktop and select NVIDIA Control Panel.
2. Go to Manage 3D settings and navigate to the Program Settings tab.
3. Select the application from the list (or click Add to browse for the .exe file).
4. Under Select the preferred graphics processor, choose:
   1. Integrated Graphics for power saving.
   2. NVIDIA High-Performance GPU for high performance.
5. Click Apply to save the changes.

Method 3: Using AMD Radeon settings (for AMD GPUs)

1. Open AMD Radeon Settings.
2. Navigate to System > Switchable Graphics.
3. Locate the application from the list or add it manually.
4. Assign a preferred GPU:
   1. Power Saving to use the integrated GPU.
   2. High Performance to use the dedicated GPU.
5. Click Apply, then restart the application to apply changes.

How to reset or change GPU preferences

After setting your preferred GPU in Windows 10, you may find yourself dissatisfied with the changes. To reset or change GPU preferences:

• Revisit Graphics Settings in Windows to select a different GPU.
• In NVIDIA Control Panel or AMD Radeon Settings, click on Restore default settings.
• If this does not work, you can try uninstalling and reinstalling the application to remove any custom GPU settings.

Troubleshooting GPU selection issues

Setting GPU drivers and preferences on a Windows computer should be relatively straightforward. Even so, you may encounter some problems, such as discussed below.

App still using the wrong GPU

This typically occurs when you do not restart the application or reboot your PC. If this occurs even after restarting, we recommend double-checking the application’s internal settings to see if it allows your GPU selection.

No option to assign GPU in Windows Graphics settings

Check if your current Windows version and GPU drivers are up to date. Keep in mind that older applications may not support your GPU selection through Windows.

Performance issues after changing GPU settings

This can occur for several reasons, including improper hardware, performance throttling, or even insufficient RAM. The simplest way to resolve this is to revert to your default settings (as instructed previously) and ensure your hardware can accommodate your GPU selection.

Best practices for managing GPU usage in Windows 10

1. Use a dedicated GPU for resource-intensive tasks, such as video editing software or gaming.
2. Use the integrated GPU for lightweight applications, such as web browsers and office apps.
3. Keep GPU drivers updated to ensure stability.
4. Regularly monitor GPU usage in Task Manager to ensure that the correct applications are using the correct GPU.
5. Adjust Power Management Settings in the Control Panel to optimize GPU performance.
6. Refrain from opening multiple tasks—even with a dedicated GPU—to prevent battery deterioration or overheating.
7. Make sure to check individual application settings; some games and software allow direct GPU selection.
8. Use a cooling pad for laptops to prevent overheating, especially when running demanding applications.
9. Regularly clean your PC’s cooling system, especially if you own a pet, to ensure that it is not clogged. Clogged systems cause your laptop to use more resources to maintain the same efficiency.

Frequently Asked Questions (FAQs)

1. Can I change the preferred GPU for all apps at once?

No, you cannot set a single default GPU for all applications. Instead, you need to configure your preferred GPU for every application. Remember to use your dedicated GPU for more resource-intensive tasks.

2. Does setting a preferred GPU affect battery life?

Yes, especially if you use the wrong GPU for an application. Nevertheless, any GPU uses power and affects battery life.

3. Why can’t I see the GPU selection option in Windows 10?

This may occur if your system does not allow switchable graphics or your drivers may be outdated. Try checking and updating your drivers.

4. Can I force Windows to use only one GPU?

This is currently not possible. You have the option, however, to disable a GPU using Device Manager; however, this is highly not recommended as it can possibly damage your CPU.

5. Does this work for external GPUs (eGPUs)?

Yes, this does. That said, we recommend that you check if your eGPU can be recognized by your current Windows version.
