 The `adapter` is a handle for our actual graphics card. You can use this to get information about the graphics card, such as its name and what backend the adapter uses. We use this to create our `Device` and `Queue` later. Let's discuss the fields of `RequestAdapterOptions`.
 
-* `power_preference` has two variants: `LowPower` and `HighPerformance`. `LowPower` will pick an adapter that favors battery life, such as an integrated GPU. `HighPerformance` will pick an adapter for more power-hungry yet more performant GPU's, such as a dedicated graphics card. WGPU will favor `LowPower` if there is no adapter for the `HighPerformance` option.
+* `power_preference` has three variants: `None`, `LowPower` and `HighPerformance`. `LowPower` will pick an adapter that favors battery life, such as an integrated GPU. `HighPerformance` will pick an adapter for more power-hungry yet more performant GPU's, such as a dedicated graphics card. WGPU will favor `LowPower` if there is no adapter for the `HighPerformance` option. The default is `None`, where the power usage is not considered when choosing an adapter.
 * The `compatible_surface` field tells wgpu to find an adapter that can present to the supplied surface.
 * The `force_fallback_adapter` forces wgpu to pick an adapter that will work on all hardware. This usually means that the rendering backend will use a "software" system instead of hardware such as a GPU.
