How To Avoid Using First Gpu -A Simple Guide!
To avoid using the first GPU, configure settings in the NVIDIA Control Panel or Task Manager, or disable it via Device Manager.
In this article, we will explain how to avoid using the first GPU in your system and provide practical tips on how to manage GPUs effectively.
What is a GPU and Why Is It Important?
A GPU (Graphics Processing Unit) is a specialized processor designed to perform complex graphical calculations. Initially created for rendering images and videos, GPUs are now essential in fields like AI, machine learning, data analysis, and scientific simulations. Their ability to handle parallel computations—processing many tasks simultaneously—makes them ideal for computationally intensive tasks. Unlike CPUs, which focus on sequential processing, GPUs excel at processing large volumes of data quickly, making them crucial for modern computing, especially in AI applications.
What is the First GPU?
The first GPU in a multi-GPU system refers to the primary graphics card installed in the first PCIe slot of the motherboard. It is the GPU that the operating system (OS) recognizes as the default for tasks like display output or processing. In multi-GPU setups, such as in gaming or deep learning, this GPU is typically used by default. However, users can configure the system to prioritize a different GPU based on specific needs, like workload distribution.
Reasons to Avoid Using the First GPU:
There are several reasons why you might want to avoid using the first GPU in your system. Here are the most common ones:
Performance Optimization:
The first GPU may not be the most powerful, especially if you have better GPUs installed in other slots. For tasks like gaming or deep learning, it’s smart to use the more powerful GPUs for optimal performance. This ensures faster processing and smoother experiences by utilizing the best hardware available, instead of relying on the default first GPU, which might not handle demanding workloads as efficiently.

Dedicated GPU for Specific Tasks:
If you have multiple GPUs, you might want to dedicate the first GPU for lighter tasks, like displaying the desktop, and use others for heavy workloads. This way, each GPU can specialize in specific tasks, like machine learning or video rendering, without overloading the first one. Distributing tasks evenly helps prevent bottlenecks and improves overall system performance, ensuring all GPUs work efficiently without one being overburdened.
Preventing Overheating:
Running multiple GPUs at high load can generate excess heat, causing thermal throttling that reduces performance. By avoiding heavy tasks on the first GPU, you can reduce its workload and help maintain lower temperatures. This improves cooling across the system and ensures that GPUs perform optimally. It also prevents overheating, which can damage hardware or lead to slower processing speeds, helping your system run cooler and more efficiently during demanding tasks.
Software and Compatibility Issues:
Some software applications may not be fully compatible with the first GPU, causing errors or performance issues. In these cases, switching to a different GPU can resolve the problem and improve functionality. If your programs are experiencing bugs or crashes on the first GPU, directing the workload to another GPU may offer better compatibility and smoother operation. This can be especially helpful in specialized applications like deep learning or 3D rendering, where performance is critical.
How to Avoid Using the First GPU:
Now that we understand why you might want to avoid using the first GPU, let’s look at practical methods for doing so. We will cover methods for both Windows and Linux users.
For Windows Users
Use NVIDIA Control Panel (For NVIDIA GPUs):
If you are using NVIDIA GPUs, the NVIDIA Control Panel allows you to configure which GPU is used for specific tasks. Here’s how to avoid using the first GPU:
- Right-click on your desktop and select NVIDIA Control Panel.
- In the NVIDIA Control Panel, go to Manage 3D Settings.
- Under Global Settings, you can choose which GPU to use for general tasks. Select a different GPU than the first one.
- You can also set Program Settings to assign a specific GPU to a particular application.
- Once done, click Apply.
Use Windows Task Manager (For Application-Based Control):
Another method is to control which GPU an application uses through Windows Task Manager:
- Open Task Manager by pressing Ctrl + Shift + Esc.
- Go to the Performance tab.
- Right-click on the application you want to manage and select Go to Details.
- Right-click the application in the Details tab, and choose Set Affinity.
- Here, you can uncheck the first GPU and assign the task to a different GPU.

Disable the First GPU in Device Manager:
If you want to completely avoid using the first GPU, you can disable it via Device Manager:
- Open Device Manager (press Windows + X, then select Device Manager).
- Expand the Display Adapters section.
- Right-click the first GPU and choose Disable device.
- This will prevent the first GPU from being used by the operating system or any software.
Note: Be cautious when disabling hardware through Device Manager, as it may affect your system’s ability to display output if the first GPU is the one connected to your monitor.
How do I prioritize my GPU instead of integrated graphics?
To prioritize your dedicated GPU over integrated graphics, start by entering the BIOS/UEFI (press F2, DEL, or ESC during boot). Look for Primary Display or Initial Display Output and select your dedicated GPU. In Windows, right-click the desktop, choose Display settings, then Graphics settings and select High performance for the app you want to use the dedicated GPU. For NVIDIA GPUs, open the NVIDIA Control Panel, go to Manage 3D settings, and set the Preferred processor to the dedicated GPU.
How do I make sure my game is using the right GPU?
To ensure your game is using the right GPU, follow these steps:
In Windows Settings:
- Right-click on the desktop and select Display settings.
- Scroll down and click Graphics settings.
- Add the game and select High performance to use the dedicated GPU.
NVIDIA Control Panel:
- Right-click on the desktop and open the NVIDIA Control Panel.
- Go to Manage 3D settings > Program settings.
- Select your game and choose the High-performance NVIDIA processor.
AMD Settings (for AMD GPUs):
- Open AMD Radeon Settings.
- Go to System > Switchable Graphics.
- Select the game and set it to High performance.
This ensures the game uses your dedicated GPU for better performance.
FAQ’S
1. Why should I avoid using the first GPU?
Avoiding the first GPU can optimize performance, prevent overheating, and ensure better resource management by using more powerful GPUs for demanding tasks.
2. How can I assign a specific task to another GPU in Windows?
You can use the NVIDIA Control Panel or Windows Task Manager to assign tasks to a different GPU by adjusting settings or setting affinity.
