I built a simple line of trees like on the screenshot, using Point Cloud Display with RailClone (latest release) and was surpised my system ran out out RAM.
I then rebuilt the same line of trees using FPP and did the spacing with a full distribution map, and collision enabled to get a evenly distance between the bushes. It almost didn't raise any usage of RAM and all is fine.
Is this a common behavior and models are handled differently in RC and FPP?
I use OctaneRender.
