## Reducing Performance Overhead

To minimize the performance impact of the Replay SDK on iOS and Android, consider lowering the quality of captured screenshots and videos. Setting the `replaysSessionQuality` to `low` can significantly reduce CPU, memory, and network bandwidth usage on mobile devices. Here's how you can do it:

```js {tabTitle: React Native}
import * as Sentry from '@sentry/react-native';

Sentry.init({
replaysSessionSampleRate: 1.0,
replaysSessionQuality: 'low',
integrations: [Sentry.mobileReplayIntegration()],
});
```

Note that the default value for `replaysSessionQuality` is `medium` and a `high` quality setting is also available.
