Game runs smoothly in studio, but is choppy when in the real game

In my game there is a spaceship that players ride in at the beginning of each round. The spaceship flies smoothly when I run the game in studio, but when played in the actual Roblox Player it is very buggy.

are you on a laptop?

also press f9

Are you positioning each part in the spaceship ahead like one stud every second? Since you can probably use model:SetPrimaryPartCFrame() to move it instead. Or, I don’t know how you can do this, but maybe a body velocity might work. If a body velocity is powerful enough I believe it won’t go down at all. But after enough testing for different moving methods, you’ll get it eventually :wink:
