fps drop when previewing the project

[Sakyra5FD1]

Hello, I am new in animate and I have a problem, they are due to drops in fps, I usually animate with 30 fps, but when I play the animation it lowers me to 11 or 15, I do not know if there are any problems, and I would appreciate your answers.

That's how Flash has always been.

Get into the habit of hitting Ctrl+Enter to preview.

check your framerate.

You could also try enabling "Match FPS" from the timeline's hamburger menu. It will keep your animation speed at 30fps with the caveat of skipping some frames to mantain performance.
