60FPS on mobile and Phaser

[bapho]

I'm doing something on Phaser on mobile phones at the moment and am wondering if minimum 60FPS performance is really necessary on mobile devices? Is there any way to play with a lower FPS (maybe down to 30) without the obvious jittering, maybe by forcing a cap on the FPS to a lower average?

60 FPS should always be your target as thats generally the refresh rate for browsers, although many games can get away with as low as 30 FPS (or possibly less for some games).

 

Depending on how your are structuring your renders (does Phaser impose this? I'm not sure) you can choose whatever fps you like as so long as everything keeps up you'll get it.

 

A naive solution using `setInterval` for your tick would look something like:

var FPS = 30function render() { ... }setInterval( render, 1000 / FPS )

I'd still advocate using `requestAnimationFrame`, which calls every 16.6ms if it can, but skip every other call (or do some maths to work out which calls to skip if you want different framerates).

Before messing with Phaser's methods, I'd try setting 

game.time.desiredFps

to 30.

Exactly, the desiredFps should be the best answer for that. Anyway, 60 would be the best perfomance, not the minimum
