How to change from 30fps in the animation view (not render)? I'm trying to figure out how to change the fps for when I press the play button in the scene.

It automatically uses 30fps and moves down if the animation uses to much resource.

I want to force it to a specific fps (1fps or 2fps etc)

thanks
In time remapping, put New to something like 1000.
This will slow down the playback to 3 fps.
