Hybrid Graphics and AMD Dual Graphics (select models only)
Select computers are equipped with either the Hybrid Graphics feature or the AMD Dual Graphics
feature.
NOTE: To determine whether Hybrid Graphics or AMD Dual Graphics is installed on your computer,
see your notebook graphics processor configuration and software Help.
Both Hybrid Graphics and AMD Dual Graphics offer two modes for processing graphics:
●
High Performance mode—Applications assigned to this mode run on the higher-performance
graphics processing unit (GPU) for optimal performance.
●
Power Saving mode—Applications assigned to this mode run on the lower-performance GPU to
conserve battery power.
Using Hybrid Graphics (select models only)
The Hybrid Graphics feature allows an application to run in either High Performance mode or Power
Saving mode, based on the application’s graphics-processing demands. Typically, 3D and gaming
applications run on the higher-performance GPU, and applications with lightweight graphics-
processing demands run on the lower-performance GPU. You can change the mode an application
uses (High Performance or Power Saving) through the Hybrid Graphics control panel.
