Although you have iPhone, iPad or Mac with ProMotion display, Safari does not render web pages at 120Hz by default, but remains locked at 60 frames per second. This results in less smooth scrolling compared to browsers like Chrome or Firefox. The good news is that Safari contains a hidden setting that allows you to activate 120Hz mode.
Na ProMotion displays, the difference is noticeable – instead of 16,7 ms, the image is refreshed every 8,3 ms, which gives noticeably smoother movement when scrolling text or images. If you Safari It always felt a bit "dull" compared to other browsers, it's precisely this limitation.

This trick works on MacBookon Pro 14” and 16” (from 2021 and newer), or even on external 120Hz monitors. If you spend in Safari a lot of time, you will definitely notice the difference – scrolling will be indescribably smooth.
Thanks for the tip. This default shutdown is a nice bonus from Appyou.
Anyway, I did it on 17 Pro Max and ABSOLUTELY NO DIFFERENCE, simply iPhone it works adaptively up to 120Hz and when it is needed, the 120Hz is there, so this is it Max it increases battery consumption but has zero effect and that's why Apple It's set up like this.
It wasn't like that for me. I have 16 pro and only after this hidden setting do I have Safari koneIt's really smooth. It was visually choppy before. So adaptive in Safari didn't work very well.
