# allowLowPower

A Boolean value to control the power level of Core Image context renders.

```
static let allowLowPower: CIContextOption
```

## Discussion

This option only affects certain macOS devices with more than one available GPU device.

If this value is True, then rendering with the context will use a use allow power GPU device
if available and the high power device is not already in use.

Otherwise, the context will use the highest power/performance GPU device.
