+## Reducing Performance Overhead
+
+To minimize the performance impact of the Replay SDK, consider lowering the quality of captured screenshots and videos. Setting the `replaysSessionQuality` to `low` can significantly reduce CPU, memory, and network bandwidth usage. 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.
