If you’re using a laptop or PC with an NVIDIA dedicated graphics card, you probably expect your games and heavy applications—like video editors or 3D software—to automatically use it. But in reality, many users unknowingly run everything on the integrated GPU instead. The result? Lower FPS, laggy timelines, stuttering gameplay, and the constant feeling that your system isn’t delivering what you paid for.
The good news is that this problem is completely fixable. Windows 10 and Windows 11 both allow you to control which GPU is used, and NVIDIA also provides its own control panel for deeper control. In this guide, we’ll go step by step and make sure your NVIDIA GPU becomes the default graphics processor, with additional checks to ensure specific apps always use it.
Let’s walk through this calmly and correctly, without skipping anything important.
Step 1: Open NVIDIA Control Panel
Before touching Windows settings, we’ll start with NVIDIA’s own configuration panel. This is where most GPU-related behavior is defined.
Begin by clicking on Windows Search and typing NVIDIA. From the search results, open NVIDIA Control Panel.
If you don’t see NVIDIA Control Panel at all, that usually means:
- NVIDIA drivers are not installed correctly, or
- You’re using Microsoft’s basic display driver
In that case, you should first install or update the official NVIDIA drivers from:
https://www.nvidia.com/Download/index.aspx
Once the control panel opens, you’re ready to proceed.
Step 2: Set NVIDIA as the Preferred Graphics Processor (Global Setting)
Now that NVIDIA Control Panel is open, look at the left-hand side and click on Manage 3D settings.
On the right-hand side, you’ll see a section called Preferred graphics processor. This option decides which GPU Windows and applications will prefer by default.
Click the dropdown and select:
High-performance NVIDIA processor
After selecting it, click Apply at the bottom.
For many users, this step alone fixes the issue. However, some systems show an error at this point—and if that happens to you, don’t worry. Let’s fix that properly.
Fix: “Access Denied” Error While Changing Preferred GPU
If you see an Access Denied error when trying to apply the NVIDIA GPU setting, it’s usually caused by a corrupted NVIDIA profile cache. This is a known issue and safe to fix manually.
Let’s go step by step.
First, open File Explorer, then click on This PC, and open your C drive.
Now, from the top menu:
- Click View
- Go to Show
- Enable Hidden items
This is important, because the folder we need is hidden by default.
Next, look for the ProgramData folder and open it.
Inside, navigate to:
- NVIDIA Corporation
- Then look for a folder named DRS
This DRS folder stores NVIDIA’s global and application-specific graphics profiles.
What to Do With the DRS Folder
- Right-click the DRS folder
- Click Delete
⚠️ Important:
Deleting this folder will reset all NVIDIA Control Panel settings to default. That’s expected and safe, but it means you’ll need to reapply your preferences afterward.
Once deleted:
- Right-click in the empty space
- Choose New → Folder
- Name it exactly: DRS
Now close File Explorer.
Go back to NVIDIA Control Panel → Manage 3D settings, select High-performance NVIDIA processor again, and click Apply.
This time, the error should be gone.
Step 3: Configure PhysX to Use NVIDIA GPU
This step is often ignored, but it’s important for consistency—especially in games and physics-heavy applications.
In NVIDIA Control Panel, look just below Manage 3D settings and click Configure Surround, PhysX.
On the right-hand side, you’ll see PhysX settings with a dropdown menu.
From that dropdown, select your NVIDIA GPU, for example:
- NVIDIA GeForce RTX 3050
- NVIDIA GeForce RTX 4050
- Or whichever NVIDIA GPU your system has
Click Apply again.
This ensures physics calculations are handled by the NVIDIA GPU instead of falling back to integrated graphics.
Step 4: Manually Force Apps & Games to Use NVIDIA GPU (Optional but Recommended)
Even after setting NVIDIA as the default GPU, Windows sometimes still assigns integrated graphics to specific apps. To avoid this completely, you can manually assign GPU preferences per application.
This is especially useful for:
- Games
- Video editors
- 3D software
- Emulators
Open Windows Graphics Settings
Click Windows Search and type Graphics.
From the results, open Graphics settings.
You’ll see a section for Custom options for apps.
Add a Desktop Application
Click Add desktop app, then choose Browse.
Now here’s the important part: you need the actual executable (.exe) of the app or game.
If the app shortcut is on your desktop:
- Right-click the shortcut
- Choose Open file location
- If it opens another shortcut, right-click again and choose Open file location
- Once you reach the folder with the
.exe, copy the path from the address bar
Go back to Graphics settings, paste that path, select the application, and click Add.
Set GPU Preference for the App
Once the app appears in the list:
- Click on it
- Choose Options
- Select High performance
- You’ll see your NVIDIA GPU listed
- Click Save
From now on, that app will always use your NVIDIA graphics card.
You can repeat this process for as many applications or games as you want.
Why This Setup Matters (And Why Windows Sometimes Gets It Wrong)
Modern laptops and PCs use hybrid graphics, where:
- Integrated GPU handles light tasks
- Dedicated GPU activates only when needed
While this saves power, Windows doesn’t always make the right decision—especially for creative software and older games. Manually setting NVIDIA as default removes ambiguity and ensures consistent performance.
Quick Checklist (So You Don’t Miss Anything)
Before closing everything, mentally confirm:
- NVIDIA Control Panel opens correctly
- Preferred graphics processor is set to High-performance NVIDIA processor
- PhysX is assigned to NVIDIA GPU
- Important apps are manually assigned in Windows Graphics settings
If all four are done, your system is now configured correctly.
Disclaimer
GPU behavior can vary depending on laptop manufacturer, BIOS restrictions, and driver versions. If your system forces integrated graphics despite these steps, a BIOS update or manufacturer-specific utility may be required. Always keep NVIDIA drivers updated from the official website.
