Build and Unity Editor play differently

When I test my game in the Unity editor everything works as it seems. Then I build it after saving both scene and project and everything is the same speed except the player (cube) which moves very very fast. If I bring down the speed, it is so slow for the editor I can’t test it in there anymore and the build version shouldn’t behave differently than the Unity editor version of my game. How do I make my build version behave the same as my editor version?

Are you using delta time in Update to move your character?

Delta time will scale movement or anything that should happen over time, to the computers speed

At the same time, the launch settings you choose (for example, “Fantastic” is going to run differently than “Fastest”) and from my experience, when I allow the player to choose these options (such as “Fastest” and not control it myself through scripting a “Settings” in-game, my delta times run… Well, really fast, compared to “Good” – so you may want to consider the quality settings being used as well.
