There is no such thing as “smooth” in space.
If you apply the physics you know are true to a simulator “as is”, you end up unable to control the ship for everything about what you think is “wrong” and even an F1 driver (worlds top reaction speeds) will have trouble issuing corrective commands effectively.
Ergo, what you need is your own solution that feels like nice gameplay to you and your testers.
The only way to achieve that is precisely what was suggested above… and a ton of trial and error.
Plus maybe hiring Picard to say engage. I think it helps
