= Switching to Your PC's Dedicated GPU =

If your game does not perform as well as you expect with your laptop, it may be running with the wrong GPU. Most laptops (and some desktop computers) have more than one GPU: an **integrated** GPU and a **dedicated** GPU.

== Windows ==

You can check if your computer has multiple GPUs by [https://support.microsoft.com/en-us/windows/open-device-manager-a7f2db46-faaf-24f0-8b7b-9e4a6032fc8c opening] the **Device Manager** and navigating to **Display adapters**. Your GPU or GPUs will be shown there.
