Modern computers, especially those geared toward gaming, content creation, and scientific computing, often come equipped with more than one graphics processing unit (GPU). These GPUs can be integrated (built into the CPU) or dedicated (a separate card). Understanding how to manage these GPUs and control which one your system utilizes for specific tasks is crucial for optimizing performance and battery life. This guide will walk you through the process of selecting the right GPU for your needs on Windows and macOS.
Understanding Integrated vs. Dedicated GPUs
Before diving into the how-to, let’s clarify the difference between integrated and dedicated GPUs.
Integrated GPUs, like those found within Intel and AMD processors, share system memory and generally consume less power. They are suitable for everyday tasks like browsing, word processing, and watching videos. However, they tend to struggle with more demanding applications like video games and professional software.
Dedicated GPUs, on the other hand, are powerful, discrete cards with their own dedicated memory (VRAM). They offer significantly better performance for graphically intensive tasks. However, they also consume more power and generate more heat. Understanding this difference is the first step in choosing the right GPU for the job.
Changing GPU Settings on Windows 10 and 11
Windows offers several methods for specifying which GPU an application should use. Let’s explore these options.

The most straightforward method involves using the built-in Graphics Settings panel.
First, open the Settings app. You can do this by pressing the Windows key + I, or by searching for “Settings” in the Start Menu.
Next, navigate to System, then Display, and scroll down to find “Graphics settings.” In some versions of Windows 10, you may need to find “Graphics” directly from the main Settings window.
Once you’re in the Graphics settings, you’ll see a dropdown menu or a search bar where you can select the application you want to configure. If the application isn’t listed, click the “Browse” button and locate the application’s executable file (.exe). These are typically found in the Program Files or Program Files (x86) folders.
After adding the application, click on its icon, and then click the “Options” button. A new window will appear, allowing you to choose a graphics preference.
You’ll typically see three options: “System default,” “Power saving,” and “High performance.” “System default” allows Windows to decide which GPU to use. “Power saving” typically selects the integrated GPU to conserve battery life. “High performance” selects the dedicated GPU for optimal performance.
Select the desired option and click “Save.” The changes should take effect immediately. You might need to restart the application for the new settings to apply.
Using the NVIDIA Control Panel
If you have an NVIDIA dedicated GPU, you can use the NVIDIA Control Panel to configure GPU settings for specific applications or globally.
Right-click on the desktop and select “NVIDIA Control Panel.” If you don’t see this option, ensure that the NVIDIA drivers are properly installed. You might need to download and install them from the NVIDIA website.
In the NVIDIA Control Panel, navigate to “Manage 3D settings.” You’ll find two tabs: “Global Settings” and “Program Settings.”
The “Global Settings” tab allows you to set default preferences for all applications. You can select your preferred graphics processor from the “Preferred graphics processor” dropdown menu. Options typically include “Auto-select,” “Integrated graphics,” and “High-performance NVIDIA processor.” Setting this to “High-performance NVIDIA processor” will generally force all applications to use the dedicated GPU.
The “Program Settings” tab allows you to customize settings for specific applications. Click the “Add” button to select an application. If the application isn’t listed, click “Browse” and locate its executable file.
Once you’ve added the application, you can customize its 3D settings. The most relevant setting is “Preferred graphics processor,” which offers the same options as the global settings. Select your desired GPU for the application and click “Apply.”
The NVIDIA Control Panel offers a wide range of other settings that you can customize to optimize performance and visual quality. Experiment with these settings to find what works best for your system and applications.
Using the AMD Radeon Settings
If you have an AMD dedicated GPU, you can use the AMD Radeon Settings to configure GPU settings.

Options typically include “Power Saving,” “High Performance,” and “Based on Power Source.” “Power Saving” selects the integrated GPU. “High Performance” selects the dedicated GPU. “Based on Power Source” allows the system to choose based on whether the laptop is plugged in or running on battery.
Select the desired profile for each application and click “Apply.” You may need to restart the application for the changes to take effect.
AMD Radeon Settings also offers other customization options, such as frame rate control and image sharpening.
Changing GPU Settings on macOS
macOS provides a more streamlined approach to GPU management, primarily relying on automatic switching between integrated and dedicated GPUs. However, there are ways to influence this behavior.
Automatic Graphics Switching
macOS typically manages GPU switching automatically based on the demands of the application. When an application requires significant graphics processing power, macOS will switch to the dedicated GPU (if available). When the application is less demanding, it will switch back to the integrated GPU to conserve battery life.
You can usually find the “Automatic graphics switching” option in the “Energy Saver” preferences within System Preferences (now System Settings in newer macOS versions). Unchecking this option generally forces the system to use the dedicated GPU all the time, which can improve performance but will reduce battery life.
To access this setting:
- Click the Apple menu in the top-left corner of the screen.
- Select “System Preferences” (or “System Settings” in newer versions).
- Click “Energy Saver” (or “Battery” in newer versions).
- Look for the “Automatic graphics switching” checkbox.
Forcing the Use of the Dedicated GPU
While macOS doesn’t offer explicit controls for assigning GPUs to specific applications like Windows does, there are some indirect methods you can try to encourage the use of the dedicated GPU.
One approach is to disable automatic graphics switching altogether, as mentioned above. This will force the system to use the dedicated GPU for all applications.
Another approach is to ensure that the application is running in full-screen mode. macOS tends to favor the dedicated GPU when an application is running in full-screen.
Finally, make sure your macOS is updated to the latest version. Apple often includes performance improvements and bug fixes in updates that can affect GPU switching behavior.
Keep in mind that macOS is designed to manage GPU switching automatically for optimal performance and battery life. Attempting to override this behavior may not always yield the desired results.
Troubleshooting GPU Switching Issues
Sometimes, you might encounter issues with GPU switching. Here are some common troubleshooting steps.
Make sure your graphics drivers are up to date. Outdated drivers can cause compatibility issues and prevent proper GPU switching. Visit the NVIDIA or AMD website to download the latest drivers for your GPU.
Check the application’s settings. Some applications have built-in settings that allow you to select the graphics processor they use. Look for these settings in the application’s preferences or options menu.
Monitor GPU usage. Use tools like the Task Manager (Windows) or Activity Monitor (macOS) to monitor GPU usage and verify that the correct GPU is being used. These tools will show you which GPU is active and how much processing power each application is consuming.
Disable or uninstall unnecessary applications. Some applications can interfere with GPU switching. Try disabling or uninstalling applications that you suspect might be causing problems.
Consider a clean driver install. Sometimes, a corrupted driver installation can cause issues. Use a driver removal tool to completely remove the old drivers and then reinstall the latest drivers from scratch.
Check power settings. Ensure that your power settings are configured to prioritize performance. In Windows, you can find these settings in the Power Options control panel. In macOS, you can find them in the Energy Saver preferences.
If you’re still having problems, consult the documentation for your GPU or operating system. You can also seek help from online forums or technical support.
Optimizing Performance Based on GPU Choice
Selecting the correct GPU isn’t just about getting an application to run; it’s about optimizing performance. Here are some considerations for different scenarios.
For gaming, always prioritize the dedicated GPU. This will ensure the highest frame rates and the best visual quality. Adjust in-game graphics settings to find a balance between performance and visual fidelity. Lowering settings like shadows, anti-aliasing, and texture quality can significantly improve performance.
For video editing and other content creation tasks, the dedicated GPU is also crucial. These applications often rely heavily on GPU acceleration to speed up rendering and processing. Make sure the software you’re using is configured to utilize the dedicated GPU effectively.
For general productivity tasks, the integrated GPU is usually sufficient. It consumes less power, which can extend battery life on laptops. However, if you experience performance issues, you can try switching to the dedicated GPU.
Ultimately, the best GPU choice depends on the specific application and your desired balance between performance and battery life. Experiment with different settings and monitor your system’s performance to find what works best for you.
