I wonder if a tick box could be added in the animation editor, named "Skip frames if animation speed is beyond framerate" (or something more concise!) and default it to "Off" which prevents it from affecting old projects, but allow everyone to choose to have it going forward.
One for the suggestion pile!
That's what I also suggested in the old topic, but since most users seem to be okay with the current system - C3 devs, probably, don't want to spend time on this feature, and don't want to add more UI elements.
