Yeah, that’s definitely a problem. Other than that, there isn’t much you can do about it other than try to avoid models that are already pretty faceted. One easy way to make it not so visible is to put on a real material/texture. Using plain shaders makes it stand out 1000000x worse than with something that has some texture to it. Just even switching from the plain white to a gravel texture will make it almost completely disappear.
You have to cut corners somewhere, but I guess CSMs are it. Small price to pay for a massive boost in overall scene quality.
