Frame Independent seconds

I know that in Every Tick, dt will be 1 second.

But how use Every second condition or Wait X seconds action as Frame Independence?

They are already framerate independent. It doesn't matter how many frames pass in a second, they just run after a certain number of seconds.

Ok, I'm question cause when my project was running at 10 fps (problems with scale rate), the "Every 1 second" conditions delayed so much.

because when your performance dips below 10 , everything becomes slower and the actions are delayed as you are experiencing ...

If the game runs *below* 10 FPS, it will start slowing down. At or above 10 FPS it should still run every 1 second if the event says every 1 second. If that's not happening for some reason, share an example.
