I have been using cocos2d-x for 10 years and I really like it.
I’ve tried with both 3.17.2 and 4.0, but when I create a new project (the one that says Hello World on the screen) and run it on my iPhone 13 Pro Max (iOS15.1) and tap the screen, the deltaTime is 1/30 (0.0333) every few times.
I can’t reproduce this on iPhone XS Max (iOS15.1), iPhone SE (iOS14.6), and iPhone7 (iOS12.5.4).
I don’t see this issue in GitHub yet although there is an issue reported back on Mojave similar to this. Create an issue so the developers can track it. I don’t, however, know a timeframe for a fix. Issues · cocos2d/cocos2d-x · GitHub
