I just recently discovered that you can enable 120 fps animation on macOS Safari by following these steps:

  1. In Safari, go to Preferences > Advanced and check Show Develop in menu bar
  2. Develop > Experimental Features and uncheck Prefer Page Rendering Updates near 60fps
  3. Quit Safari

Now when using Safari you can experience any webpage that supports up to 120fps.

However, I was wondering if there was any way to do this on iPad/iPhone? I use some animation-based webpages on a daily basis that support 120 fps.

The same option as in your question is available on iOS: Settings → Safari → Advanced → Experimental Features → Prefer Page Rendering Updates near 60fps. This option is enabled by default.

  • Amazing! I would have never thought to look there haha

There is no specific Safari setting for your question. However, in the Settings app, you can turn the ProMotion (120hz) feature on, on your iPhone/iPad. (Settings > Accessibility > Motion > Limit Frame Rate)

Make sure you are using the supported devices for ProMotion:

  • iPhone 13 Pro and Pro Max
  • iPhone 14 Pro and Pro Max
  • iPad Pro (2017 or later)
  • AFAIK this only allows to limit the frame rate to 60, not to enforce 120 in Safari.
