Two Graphics Adapters in Envy Desktop?

[BuffaloSoldier]

I have an Envy all-in-one, 27-b019. It says that I have 2 graphic adapters:

- Intel HD Graphics 530

- NVIDIA GeForce GTX950M

How can I have 2 different graphics adapters in this PCP? How do you know which adapter is currently used? I want to install a game that recommends an NVIDIA GeForce. Are these switchable somehow?  How do you manage this? How do you tell the PC to use one adapter or the other?

Your machine has

    - Intel HD Graphics 530 which is Integrated GPU (also called iGPU) which comes with CPU (one part of CPU)

    - NVIDIA GeForce GTX950M which is dedicated GPU (or dGPU which is removable)

(a) For laptops/notebooks, by default, system will use iGPU and will automatically use dGPU when required. But you can control and switch them

(Note: Many AIO machines work similar to laptops/notebooks)

(b) On normal desktops, when adding dGPU system will automatically disable iGPU.

OK thanks. So basically, if I use a cake that needs the dCPU, it will switch automatically on my Spectre notebook?
