If you’re running the April Update, Windows 10 now includes a new Settings page that lets you change advanced graphics settings for individual apps, both UWP and classic. This could be handy if you’re facing performance problems with a particular app and you’re blaming your innocent PC.
Go to Settings > System > Display. Scroll down and click Graphics Settings. One the next screen, select the classic or UWP app you want to configure and click Add.
Now, click the app’s name and click Options. Here, you can choose between different graphics specifications like System default, Power Saving, and High Performance. The high-performance setting allows the app to take advantage of the discrete GPU on your system.
