You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? making a game not have a ton of server lag so a rocket can actually smoothly launch
What is the issue? server lag is making it go really slow (see gif)
What solutions have you tried so far? all of them. Trying to turn on streamingenabled hasn’t worked and has only caused a ton of clientside lag, and every solution I can find is for client lag and not server lag
it feels like nobody has these lag issues except for me, and i’m getting really frustrated because of it
Maybe reduce parts used in the rocket, most of the server lag is caused by the model having too many parts, so I recommend reducing the parts, or you can add a low graphic mode. Both would require a lot of effort as to re-design the rocket. But this also could be caused by the amount of scripts running at once, make sure not too many scripts run at once, that could be something causing the server lag.
You shouldn’t launch the rocket from the server. Instead, send a RemoteEvent to all clients, so the rocket launch can be simulated locally on each player’s device.
And how many scripts are running in the background, that could be the reason to why the rocket is moving slowly, it could also be the faulty roblox engine.
