Samemrecebi (talk | contribs) (Added NVIDIA prime option for AMD GPUs that was missing. Also made it clear that AMD integrated GPUs will also work with NVIDIA prime offload. I added this change to the old wiki too and was copied from there.) |

This step will be essential regardless of which configuration you later adopt. | Before we can continue, we must first determine the bus ID values for both your Nvidia and Intel and AMD GPUs.

Offload mode puts your Nvidia GPU to sleep and lets the Intel GPU handle all tasks, except if you call the Nvidia GPU specifically by "offloading" an application to it. For example, you can run your laptop normally and it will use the energy-efficient Intel GPU all day, and then you can offload a game from Steam onto the Nvidia GPU to make the Nvidia GPU run that game only. For many, this is the most desirable option. | Offload mode puts your Nvidia GPU to sleep and lets the Intel GPU handle all tasks, except if you call the Nvidia GPU specifically by "offloading" an application to it.
