=== Introduction
== Introduction
The objective is to enable NVIDIA GPU of an Optimus-based laptop *all the time* and use it for every single activity.
Please do not use this guide if you want to render your desktop using the integrated GPU and specifically select applications to be rendered using the NVIDIA GPU.

First, you need to see if you really want to achieve this.
==== Why would you want to do that?
1. The use of NVIDIA GPU all the time would allow for smoother transitions and richer animation effects. Premium desktop environments like GNOME would benefit a lot from this.
2. Enabling the NVIDIA GPU all the time would lead to lower CPU load and memory consumption which otherwise would have been high due to added in-memory video buffer.

==== Why would you not want to do that?
1. With the NVIDIA GPU used all the time, there would be a slight increase in battery consumption which should not be a concern if your device is used while being plugged in.
2. Increased generation of heat from the all-the-time enabled NVIDIA GPU can be worrisome. You would not want to play AAA-titles on Proton while placing your laptop on your lap.
