Improved “Graphics Settings” for performance management
The updated graphics settings page (Settings > System > Display > Graphics Settings) now allows you to better control which graphics processor your applications use.
Thanks to this update, the list of applications and the preferred GPU (for energy saving or high performance) are pre-populated with maximum efficiency, which improves performance management when using default applications.
If the application is not listed, you can add it using the application selection drop-down menu. Also added a search box and a filter for the list of applications.
