You can see through the debug mode or remote preview how the frame rate drops
This doesn't happen on my Windows laptop. CPU utilization goes up to 30% for a short period, but the tween runs smoothly and there is no fps drop. I'm guessing the problem is either with Tween or hierarchies on MacOS/IOS.
I would try these things:
- Check if WebGL2 is enabled in Debug Mode.
- If possible, try a different browser.
- Try using MoveTo instead of Tween.
- Try using Pin instead of adding objects as children.
- Test with sprites only, without the text objects.
- Check if you have the same issue with the "Skeleton hierarchy" example in C3.
