Transform.position not working properly after Build

When i want to change the Transform.position value from one of my gameobjects (In this case of an Bullet) in the Game Preview it’s working correct with the proper speed and so on, but when I build and run it it gets a lot slower then it is in the Game Preview.

Here is the Code I use for the Bullet.

Found the Answer now myself, needed to change something in the Game View. Didn’t have VSync on thats why it was in the Game Preview faster then after I build my Project.
