Vehicles not synchronizing 800+ Players

Dear FiveM Support,

We are writing this report about vehicles that are not synchronizing to the network when there are too many players in the scope. This usually occurs when there are 800+ players on the server. The vehicle exists as if it was spawned client side, others players cannot see the entity. The entity is spawned from the server-side, using the Native CreateVehicle RPC. Could you tell us why is this happening and as a server, what could we do about it?

Thank you.
