question about culling for better proformance in game

hi guys i have a question about culling in ue4, specifically this tutorial video: Fortnite Stylized Cull\Growth Effect -Material - [UE4] - YouTube
would this way of culling help with performance in game ?

I mean… it reduces the amount of meshes on screen, so obviously it will improve your performance. But there aren’t many games where using this effect fits well, you usually don’t want to shrink everything that’s more than 20m away
