Nanite Performance is Not Better than Overdraw Focused LODs [TEST RESULTS]. Epic's Documentation is Dangering Optimization.

I’m kinda confused by what you mean here, since you can’t just “increase” geometry. That makes it sound like flat subdivisions will do the trick when Nanite will detects this action and just collapses them into no clusters or large clusters. Unless you have a way to share how flat subdivisions can be kept for clusters? What my test showed(and I replicated in 5.4) is that increasing clusters via detail(noise, rock/wood patterns, doesn’t matter) will increase cost due to the cluster overdraw they induce.

Not a flat subdivision, a very subtle displacement will do the job. However, of course, the clusters will appear based on the camera’s distance, and beyond a certain point, these clusters will collapse.
