This laptop has a MUX switch!

Integrated MUX Controller – Choose your graphics options depending on your needs with these three options:

Optimus – System automatically chooses between the dedicated GPU and integrated GPU based on application. Recommended for daily use.

dGPU – Disables the integrated graphics and runs directly off of the graphics card. A very exciting feature for content creators and gamers, but consumes far more battery life when on the go.
