Question Sudden movement

Hello everyone !,
I'm making a minigame with a spaceship, rotating seems to rotate quite clean and smooth, but in the attached video you can see how the speed seems to be bumping, it doesn't look very smooth, I would like to know what I'm doing wrong, or what do I need to apply to make the movement look as smooth as possible.

Thanks for the advice on posting the code.
As for your code, it works a little more fluently but it continues to make sudden jumps. Which may be due?.
PS: If I don't limit the fps and it's at 1000fps it looks fluid
