How to Change Default Graphics Card in Windows 11
Changing the default graphics card in Windows 11 ensures that your applications use the most powerful graphics card available. This can lead to better performance and an overall smoother experience. Here’s how to do it:
Step 1: Open Settings
First, open the Settings app by pressing the Windows key + I.
To start, you need to access the Settings app. Pressing the Windows key + I is a quick shortcut that takes you directly there.
Step 2: Navigate to System
Next, click on the “System” option in the Settings menu.
The System tab houses many important settings, including the ones we need to change the graphics card.
Step 3: Go to Display
After clicking System, choose “Display” from the left-hand menu.
The Display settings are where you’ll find options to customize your screen, including selecting which graphics card to use.
Step 4: Scroll Down to Graphics Settings
Scroll down until you find “Graphics settings” and click on it.
The Graphics settings option is usually near the bottom. This is where you can manage settings for individual applications.
Step 5: Choose an App to Set Preferences
Click “Browse” to add an app or choose one from the list already provided.
Whether you want to add a new app or change settings for an existing one, this step lets you specify which graphics card to use.
Step 6: Set Graphics Preference
Select the app, click “Options,” and then choose between “Power saving” (uses integrated graphics) or “High performance” (uses dedicated graphics).
This is the main step where you assign the desired graphics card to the application, maximizing either performance or battery life.
Once you complete these steps, your chosen applications will use the designated graphics card for better performance or power saving, depending on your preference.
