Your question is quite long and I don’t understand fully what you are trying to explain 
Just some common things: If something is too fast moving, try a slow-operator.
And for easier control you can try to convert your physX into standard particles.
Render time can make a difference, deprnding if you use instances or individual meshes.
But someone else will maybe know better. I have never worked with Corona.
