Hide actors behind player's camera view.Show them when in front

I have a scene with 165 skeletal mesh actors and they drag performance down.
Lods help but not much. What really increases frame rate is when i set their visibility to hidden. Is there a way to hide actors behind our view. Its a 3rd person game so behind the camera view. So when we rotate with mouse our camera objects hide and unhide accordingly.

thanks in advance

Frustum culling should already be taking place I believe. It’s possible that the drawcalls aren’t really where the bottleneck is though, it may be the anim blueprints or something else. I would try to get a more detailed understanding of this by using the profiler.
