Lag problem while making vehicle slide game (Urgent)

I have a problem while making a map in Rec Room.
I am making a car slide like game. There is a big slide with a bunch of obstacles.
Its started good, i almost finished this map, but as i saved this map, my game started to lag too much.
What can i do? Because i need to finish this map before tomorrow.
Can it be because of a huge buildings or something?
By the way, the ink was used only at 50%

I can take photos if needed

Can you give more details about how it’s lagging? Is it consistent lag like 20-30fps or, are there massive stutters?

My only theory as to why this may be happening is there’s a lot of objects colliding with each others (like vehicles or physical objects). Otherwise, I’m not sure what could be wrong.

I would suggest, if you really need to resolve your problem, save everything important in your room as an invention, and spawn it all in a fresh room.

Try this

Reduce the number of objects and their complexity. Even though your ink usage is at 50%, having a lot of complex objects can still cause lag.

Ensure that there aren’t too many objects with collision enabled. Too many colliding objects can cause performance issues.
