I'm wondering how much less fps can I expect from an exported iOS game vs the preview over wi-fi?
My game runs ok (~30fps) on preview over wi-fi, but I started getting worried after all the posts on mobile performance the last days.

The only way to know anything accurate ... is to try.
From my experience so far, not having 60 fps in a browser on PC/mobile, generally means worse on mobile as wrapped package.
