# Alternate render method

Some iOS apps with custom controls, lots of animation, or complex visual effects, can benefit from alternate render methods used by the Cobrowse iOS SDK.

There may be a small performance cost for some apps, particularly noticeable in apps with heavy scrolling.

You may test this alternate render method by adding a plist entry to your `Info.plist` as follows:

```markup
<key>CBIORenderMethod</key>
<integer>2</integer>
```

If you've been able to test this alternate render method in your iOS app, we would love to hear your feedback. Please drop us an email at <hello@cobrowse.io>.
