There are 11 ground clutter models that suffer terrible "pop-in" when traversing any map that contains the affected models.
Taking Altis and Stratis as examples as they are vanilla Arma 3 maps, whether you are walking, running or inside any land vehicle, these clutter models don't fully render in till you are literally on top of them.
These are the clutter models that are affected by this....
