Physics on Mobile browser work differently?

I made a simple game with a ball bouncing on pegs and set gravity to -500. It feels great when playing on Mac/Win and HTML5 (desktop) but when I try the game on mobile browsers (Safari, Chrome), gravity does not feel right. It feels like gravity was set to -1000. Am I missing a setting for HTML5 on mobile browsers?

Perhaps the phone has a 120Hz display? What kind of settings do you have in game.project for updated frequency, swap interval and fixed timestep?

Use fixed Timestep is disabled and below are my display settings–

I’m using all default settings btw.

I’m also trying it on an iPhone 14 which should have a 60Hz display.

@britzl Is there anything I can do to have my game behave similarly across multiple browsers regardless of what monitor refresh rate the player has?
