FPS drops when GUI can not properly renter complex animation.

Hello. I will summarize my adobe project problem.

The problem of my adobe animate cc 2019 problem was

- my frame rate changes when I preview my animation (before exporting). However, when I export it, it works, which means 24fps is working.

So, when I'm creating my project and previewing to figure out the right timing, my project moves slow and frame rate changes to about 8fps or low.

First.

1. I contacted Adobe Korea 3times and they gave me solutions.

- 1) uninstall the whole adobe system, and install it again with adobe cleaner. (I tried this solution 3 times) = it didn't work.

- 2) Reset the adobe animate cc system. = it didn't work.

2. Korea Adobe couldn't solve the problem, so they advised me to contact US adobe support-chat. I contacted Adobe 2 times.

- 1) First operator told me that it might be the problem of my home network. So for now, the best solution is changing the network system to better one. = I actually bought the better network system but it didn't work..

-2) Second operator investigated the issue and found out that FPS drops when GUI can not properly renter complex animation. Also, she said that it is an expected behavior which means that the complexity of the animation and the speed of the computer playing the animation affect the smoothness of the playback. She gave me a solution to determine optimum frame rates, test my animations on a variety of computers. = So I tried on a variety of computers at the apple shop. I tried on the most expensive and the best apple computers. However, it was the same or worse.

I would be very happy to know the solution for this.. Thank you (()))
