You can choose custom graphics performance settings you prefer for apps in Windows 11.
This allows you to specify which GPU you prefer to use by default for specific Microsoft Store and Desktop apps. Preferences may provide better app performance or save battery life. Choices may not take effect until the next time the app launches.
Generally, the power saving GPU is the integrated GPU on a system, and the high performance GPU is the discrete GPU or external GPU. If you have both a discrete GPU and an external GPU on a system, the external GPU is considered the high performance GPU.
Apps are always allowed to have the ultimate choice of which GPU to use, so you may see additional apps that do not follow the preferences you set. In that case, look for a setting within the app itself to choose a preference.
This tutorial will show you how to change the graphics performance preference for desktop and Microsoft Store apps for your account in Windows 11.
