How Optimus Technology works
When the system is powered up and is displaying just the desktop, the dGPU will be
powered off. In this case the system is running in the same way as a system without
a discrete graphics solution. However when an application that requires use of the
dGPU is run (e.g, a game or HD Video), the dGPu is powered on and takes over the
processing duties. If the program is closed, then the dGPU will be powered back
down again until required.
Customization
Options
Although
Optimus
is
completely seamless to
the user, NVIDIA also
allow customization op-
tions within the control
panel (see
“Optimus™
Customization Op-
tions” on page C - 29
).
UMA Mode & Performance
UMA Mode
is designed for
maximum power saving
, however this does have an affect on
the system’s overall video performance (as it is based on the Power saver power plan).
If you require better video performance then it is recommended that you use
Optimus
Mode
. Alternatively you may switch the
UMA Mode
power plan to Balanced (however pow-
er savings will be reduced in this case).
Note that when the power plan is set to UMA Mode the GPU LED indicators may no longer
display the correct status.
