Because of the way I load the maps in my new engine I can choose either to have many static mesh bodies or just few. Would it make a difference in terms of speed if I use 500 static mesh bodies on a map or just 10? Both alternatives will represent the same geometry. If there is a difference, how much?
Yes sure it have surely a difference, but the difference don't depending only from newton.

If the 3d system can do the same tricking you can surely gain some ressources and speed.
It remember me a mesh Exemple 3ds save in multiple object or in only one,
the 3ds saved in multiple object normally cost more to render and consuming more ressources.
If you have 500 object it's sure that the system have 500 object in a list and you have 500 intances.
If you render 500 object it is surely more slow that render only 10.
It surely depending on the object sorting method too, from both engine.
About the other question i'm not so sure.
