How to Switch Between Dedicated GPU and Integrated Graphics

How to Switch Between Dedicated GPU and Integrated Graphics:

The laptop Hard work. They have to provide good performance to users while being frugal with their battery usage. so Gaming laptop Or those with a high-performance dedicated graphics card have a low-power integrated graphics chip to deal with everyday tasks like YouTube or browsing Facebook.

While most software programs have no problem choosing the right GPU for the job, sometimes they get it wrong. This is why it is good to learn to switch between your dedicated GPU and integrated graphics.

Dedicated vs. Integrated GPUs Explained

A quick comment on what these two words mean. A dedicated GPU has its own separate processor package, Rama, Cooling and circuit boards. An integrated GPU sits inside a microchip package similar to your CPU and also shares the same pool of RAM.

In general, dedicated GPUs are very fast and do not limit the performance of other components due to shared cooling and dependence on memory resources. If your fancy video game accidentally runs on the integrated GPU, then you are possible to have an unmistakable slide show.

A note on graphics output

When your system has two GPUs, some graphics output may be directly connected to one GPU or the other. For example, in the laptop system we used for this tutorial, the HDMI output is directly connected to the Nvidia dedicated GPU. However, the mini-DisplayPort connector on the laptop is wired to the integrated GPU.

This is an issue, because if you want some features (such as HDR) on an external monitor, it will only work on the HDMI connector. Likewise, since Nvidia Gsync The variable refresh rate technology will only work on DisplayPort, this feature is impossible to use on external displays here. Since the DisplayPort connection of the laptop in question is directly connected to the laptop’s internal LCD panel.

On desktop computers that do not have switchable graphics, a common mistake is to connect the screen to the integrated GPU’s HDMI port. Since most desktop systems are not set up to allow dynamic sharing and switching between two GPUs, it will not allow your dedicated GPU to be used with screens attached to an integrated GPU.

The bottom line is to make sure that you have connected your display to the correct GPU port!

Checking that both GPUs are working

Before you try to switch between dedicated and integrated GPUs, it is worth making sure that both are actually installed and working.

  1. Open up start menu And type device Manager.
  2. Choose device Manager From the results.
  3. under which display adapters, Expand the list.
  4. Check that two GPUs are listed.

If you see two GPUs, you are good to go. Assuming that you have only two GPUs in the system and the two you want to switch between, they are listed.

Housekeeping tips

The last bit of housingkeeping you should do before messing around with manual GPU switching is to make sure everything is up to date:

  • Are you running the latest version of Windows?
  • Are you driving the latest driver for Both GPU?
  • Have you installed the latest version of the GPU companion software?

The last point may be particularly important, as modern GPUs have two software components. The first is the GPU driver, which makes it possible for Windows to actually talk to the hardware. Another is the suite of utilities that come with GPUs these days. This utility is usually the key to determining which GPU an application will use.

How to switch between dedicated and integrated GPU

The computer we are using in this example has a Geforce 1660 Ti dedicated GPU and Intel UHD 630 integrated GPU. It uses the Nvidia Optimus system to dynamically switch between them based on which is best suited.

How to switch gpu

Here’s how you can override that setting:

  1. Right-click on the desktop and select Nvidia control panel.
  1. Switch on Manage 3D settings In the left-hand pane.
  2. Under the liking Graphics processor, Choose which three settings you prefer.

How to assign a specific GPU

To determine a specific GPU on a per app basis:

  1. Right-click on the desktop and select Nvidia control panel.
  1. Switch on Manage 3D settings In the left-hand pane.
  2. Switch to Program settings Tab.
  3. under which Choose a program to customize, Select Relevant applications.
  4. under which Select the preferred graphics processor for this program, Select GPU you’ll like.

While we do not have an AMD GPU on hand, the process is very similar. Just open the AMD Catalyst Control application and look for the section with “Switchable Graphics” or similar name.

Regardless of your GPU brand, you can set per-app GPU preferences in the latest version of Windows 10 display settings > Graphics settings. You can open the display settings by right clicking on the desktop.

Don’t forget about in-app settings

Many professional applications and even video games will tell you which GPU to use in your own graphics settings. This should in most cases override other settings on the system. If you can’t seem to get GPU changes in the stick, check if the app in question has its own settings.

Checking which GPU is working

It has been told which GPU should work, how to specify it, but how can you ensure that your settings have actually worked? If you have the latest version of Windows 10, you can simply open Task Manager and switch to the Performance tab.

As you can see here, two GPUs are listed: GPU 0 and GPU 1. In most cases GPU 0 must be integrated, but you can also see their names, just to be sure. If your dedicated GPU is running an application, you will see that this usage percentage is shoot up. What the GPU is not doing much should be close to the idle percentage.
