Huge fps drop

I have a game object with a lot of children that when looking at causes fps drops to about 20 (usual 120). When zooming it the fps goes up to around 60. I understand it that it happens because its rendering all the objects when I’m looking at them, so I was wondering if there was a way to optimize it someway?

I just love answering my own questions… If anyone comes around the solution is to use occlusion culling, more info can be found here: Unity - Manual: Occlusion culling
