The default settings are:
• Power Saving Plan:
• On Battery—Automatic GPU selection
• Plugged-in—Automatic GPU selection
• Balanced Plan:
• On Battery—Automatic GPU selection
• Plugged-in—Automatic GPU selection
• Performance Plan:
• On Battery—Automatic GPU selection
• Plugged-in—Automatic GPU selection
Note: The user must change the On battery Power Plan setting to Force Power-
saving GPU to enable extended battery mode on a Power Plan switch.
Direct 3D and OpenGL applications that start after extended battery mode is enabled
will be forced to render on a power-saving GPU. Enabling or disabling extended
battery mode will not affect the running applications.
2.2.3 OEM Specific PX Application Profiles
The introduction of OEM specific PX application profiles will enable OEMs to set their
application profiles that can be different from the system (AMD default) application
profiles.
There are three sets of PX application profiles: 1) user, 2) OEM, and 3) system (AMD
default). The user application profile settings take precedence over OEM settings,
and OEM settings take precedence over system settings. Only the highest precedence
application profile is visible to the end-user.
This section outlines the steps that have to be executed in order to deploy OEM
specific PX application profiles.
2.2.3.1 Creating OEM XML with PX Application Profile Data
Details:
The following figure shows an OEM XML file that runs application1.exe on a high-
performance GPU, application2.exe on a power-saving GPU, and application3.exe on
the default GPU.
