Using Your XPS Laptop

NVIDIA Optimus

Technology

Your XPS laptop is equipped with NVIDIA’s

Optimus technology. The Optimus

technology is designed to maximize

performance and user experience on your

computer, while minimizing the impact

on battery life. It enables you to combine

the graphic processing capability of the

integrated Intel

®

graphic processing unit

(GPU) with the discrete NVIDIA GPU while

running graphic‑intensive applications such

as 3D games. The NVIDIA GPU is turned on

only for preset applications and thus extends

the battery life.

The Optimus solution is enabled through

an application profile. When an application

is launched, the video drivers check if the

application has an associated application

profile.

If an application profile exists, the NVIDIA •

GPU is turned on and the application

runs in performance mode. The NVIDIA

GPU is turned off automatically when the

application is closed.

If an application profile does not exist, the •

integrated Intel GPU is used.

The default list of application profiles

is updated frequently by NVIDIA and is

automatically downloaded to your computer

when you are connected to the Internet.

You can also create application profiles for

any application on your computer. This

may be required for newly released games

or applications that do not have a default

application profile.
