Rendering Functionality Changes in UE 5.1

Hello Everybody, I’m looking for information on the ECS Framework for MASS. Yes I understand to my knowledge that it is currently still in the experimental stages. But I want to know more about it for the potential of implementing it at some point of my own accord. Since I need a system thats better for rendering large groups of units, I just kind’ve wanted to know the upsides and downsides of the subject in terms of performance, use cases and the like. Thank you all!
