- Switchable GPU technologies allow for optimized performance and power consumption in portable.
- You can easily customize the use of the dedicated or integrated GPU in both NVIDIA as in AMD through its control panels.
- Manual settings ensure your applications take advantage of graphics power when you really need it.
- The latest versions of Windows and drivers Officials improve compatibility and control over which GPU to use in each case.
Have you ever wondered how to get the most out of your laptop's graphics card or how to save power when you don't need as much power? Many modern laptops feature two graphics cards: one integrated (usually Intel) for everyday tasks and other dedicated (NVIDIA or AMD) for demanding applications like games or editing software. Switching between the two efficiently can make a difference in both performance and battery life.
In this article I am going to tell you in a comprehensive and detailed manner how technologies work and are configured NVIDIA Optimus y AMD Switchable Graphics. You'll see not only the steps to adjust your equipment, but also the key concepts to understand what happens behind the scenes. If you have a laptop from ASUS, Dell, Lenovo or almost any brand with hybrid graphics, what you are going to read here will be of great interest to you.
Why do commutable graphs exist?
Laptops with hybrid graphics They have a system in which two types of GPU coexist: the integrated (usually manufactured by Intel and included in the processor itself) and the discreet or dedicated (from NVIDIA or AMD). The reason? Optimize energy consumption and the graphics performanceWith the integrated card, you can reduce battery consumption and heat when browsing the internet or writing documents. When you launch a video game, design program, or want to edit high-resolution video, the system can automatically activate the dedicated card to ensure a smooth, high-quality experience.
This translates into greater autonomy and useful life battery life, while allowing you to enjoy the extra power only when you really need it. They're also found in desktop computers, although switching is less common outside of laptops.
How does the system know which GPU to use?
The key is in the smart management that the operating system performs together with the drivers and the hardware. Technologies like NVIDIA Optimus o AMD Switchable Graphics make this dynamic change possible without user intervention in most cases. In Windows 10, especially since version 2004, Microsoft has further improved control over which applications and GPU they use by default.
It may happen that certain games or applications are not detected correctly and do not take advantage of the dedicated GPU, which causes Low frame rates, performance drops, poor resolutions, or even pixelated video. Therefore, knowing how manually configure which graph to use is essential to get the most out of your laptop.
Before you start: Check your drivers and hardware
Before changing anything, it is crucial to make sure you have the most current drivers installed for both integrated and dedicated GPU. From the Device administrator Windows, check that both cards appear correctly and are enabled. If any of them display an error or don't appear, install the drivers from your laptop manufacturer's official website or from NVIDIA/AMD itself.
Configuring NVIDIA Optimus step by step
By default, the NVIDIA Optimus driver decide for yourself which graphics card is most suitable depending on the program. For example, a Web navigator will use the integrated one, while a demanding game will activate the dedicated one. But if you need to force the use of the High-performance NVIDIA In a specific application, you have several ways to do this:
Global Adjustment via NVIDIA Control Panel
- Right click on the desktop and select NVIDIA control panel.
- Go to Manage 3D settings in the menu on the left.
- In the Global setting, locate the drop-down menu Preferred graphics processor.
- Select option High-performance NVIDIA processor.
- press Apply To save the changes.
With this setting, all applications (except those blocked by the system) will use the dedicated graphics card unless otherwise specified later.
Adjustment by application
- From the same NVIDIA Control Panel, go to Program Settings (Program settings).
- Choose the desired app from the drop-down menu or add it if it doesn't appear in the list.
- Below, select as your preferred processor the High-performance NVIDIA.
- Save changes with Apply.
This way you can make sure that critical programs such as video editors, 3D development or demanding games always use the maximum power available.
Advanced Settings: Resolution and Scaling
Some image problems can be caused by how the GPU handles the image. resolution and scaling when launching games or videos. To adjust this:
- Open the NVIDIA control panel.
- Go to Change resolution in the display section and adjust the resolution and refresh rate options according to your monitor.
- En Adjust the size and position of the desktop, check the scaling tab and disable it Override scaling mode for games and programs if you need personalized management.
Technical aspects of NVIDIA Optimus
Optimus technology recognizes, through DirectX, DXVA (video acceleration), and CUDA calls, if an application requires the dedicated GPU. The system is based on a advanced routing layer within the driver that manages resources according to the needs of each app, without them interfering with each other.
Optimus does not use hardware multiplexers; instead, the The image generated by the dedicated GPU is transferred to the frame buffer of the integrated GPU. using main memory, transparently to the user. It is a solution that is both efficient and easy to maintain for manufacturers and valid from Windows 7 and later. It is also compatible with GNU/Linux from recent drivers, although projects such as Complete guide to enable virtualization in BIOS and UEFI step by step to manage manual or automatic switching between GPUs.
Configuring AMD Switchable Graphics on Radeon-based Laptops
AMD offers similar functionality to Optimus. Out of the box, Windows decides which GPU is used based on the preloaded profiles of the controller, but it is possible to deeply customize this behavior.
Automatic configuration and blocked applications
As a rule, less demanding applications use the AMD integrated, while the heavy ones activate the AMD dedicated. However, there are some programs marked with a padlock icon: means that the operating system does not allow you to modify the graphics processor used for that app, for example, some browsers or essential utilities, which will always run in power-saving mode.
Manually Configuring Switchable Graphics
- Right click on the desktop and select AMD Radeon Settings.
- Access the section System and then to Switchable Graphics.
In the initial view you will see the running applications (Running Applications), with the GPU assigned to each. For non-blocked applications, you can choose between:
- Power Saving: Uses the integrated GPU, saving power but sacrificing some performance.
- High Performance: Uses the dedicated GPU, with higher consumption but more power.
- Based on Power Source: Automatically switches depending on whether the laptop is plugged in or on battery.
The change will be applied when you launch the app again.
Add and manage applications manually
If your program isn't listed, you can add it by following these steps:
- En Switchable Graphics, Accede to Installed Profile Applications.
- If it doesn't appear, use Browse to search for the executable and add it manually.
- Assign the desired graphics mode as before.
What about external monitors?
A common question is whether connecting an external display via HDMI or DisplayPort reduces graphics performance. In general, The system GPU settings are still applied and the video signal adapts to the capabilities of the graphics chip and the connected monitor, without reducing the power of the dedicated GPU.
Technical aspects and operation in BIOS/Firmware
Do not forget that the activation of the switching functions It depends not only on the hardware, but also on the BIOS of the laptop. Even if your computer has a dedicated graphics card, you won't always be able to switch between the two if the manufacturer has blocked it in the firmware. Therefore, it's important to consult your computer's manual or technical support and make sure you have the updated firmware.
