React native does not support screen refresh rate

Please provide all the information requested. Issues that do not follow this format are likely to stall.

Description

When running a react native app on a device that has a refresh rate other than 60, react native apps still run at 60 fps. This means that if you have a device like a Samsung Galaxy S20, which runs at 120 fps, every react native app will feel sluggish, slow and underperforming.

React native should honor the screen’s refresh rate and use that for rendering.

Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. Use a phone with a higher refresh rate than 60 (e.g. Samsung Galaxy S20, Oneplus 7T (or higher))
2. Start any react native app
3. See that the app is slower than every app on the phone

Expected Results

I expect that the app runs smooth on all refresh rates above 60.

Apart from all this, there are a few places where 60 frames are hardcoded.

iPad Pro has 120Hz. There are rumors that iPhone 13 will have 120Hz as well, which we’ll see in a few weeks.
