ios - Why is a game slower (fps) when using a bigger display? -

i'm making game in swift using spritekit. have skspritenode running basic action. when run on xcode using iphone 4s, smooth(high fps). however, when run on bigger display ipad, it's slow (low fps). here's basic code use:

var node = skspitenode() //... self.addchild(node) //... let action = skaction.scaleby(4, duration: 2)   //... node.runaction(action) 

any ideas why? in advance... anton

this common phenomena has nothing different devices, simulator of xcode.

don't compare simulator-rendering real device-rendering.

if game works on iphone 4s, work on other device. simulator isn't powerful device. in 99.9% of cases, performance on real device better.

so if ever want check performance of game, check on real device. apple allows every developer test on device, without buying developer-account.
