I have a big layout with hundreds of objects that move. I want them to only load when the player gets near them. How can I do this?

Alternatively, will it still affect performance if I just disable the object's ability to move when they are out of vision?

With hundreds of objects you should definitely disable behaviors for objects which are too far away. You can use "Is on screen" condition or distance() expression. So you can do something like this:
Every 2 seconds: Pick EnemiesFamily where distance(EnemiesFamily.x, EnemiesFamily.y, Player.x, Player.y)<2000 EnemiesFamily enable behaviors Pick EnemiesFamily where distance(EnemiesFamily.x, EnemiesFamily.y, Player.x, Player.y)>2000 EnemiesFamily disable behaviors

Note, that if you have too many objects, even disabled behaviors can affect performance. You might want to create objects only when player gets close to them, and destroy objects which are left far behind.
