There is definitely a bug in the Tree LOD algorithms, besides a regression in LOD ring distance compared to alpha. I’ve extensively explained and illustrated the problem which a little more complex than just LOD distance.

I’m glad seeing this discussion is gaining votes which will make it more prominent maybe in the next Dev Update. Unfortunately having different discussions about the same topic is also diluting the votes and gives less change any single one reaches the minimum number of votes needed to be in the top 30.
PS: @BilingualHarp7 thank you for the detailed explanations! Sometimes you’re not noticing any change in the trees appearance because they are most likely drawn using impostors at a distance. This means Trees LOD setting is actually really controlling LOD ring distance (with a bug I’m detailing in the aforementioned discussion), and density as well, only at a distance you’re looking at pre-rendered trees on a texture and they can be drawn once only and displayed on many subsequent frames with high details without fps loss as a consequence.
