With that plant at least, overdraw is pretty minimal. I think density is also a big factor of it, and I’m beginning to come to the belief in testing that Nanite might prefer more dense foliage over less, because it makes it easier to do occlusion culling sooner. That being said, the only time my game really hitched was when I was moving fast directly above the foliage, so I think part of the cost is just moving things in and out of cache.
