We are working on a visualisation project that requires representing the position of over 10000 elements. From basic testing, it appears that even having an empty actor with nothing to be rendered is causing a huge hit to FPS. I am not an engine expert so I’m not sure where to start looking for working with a large set of data such as this.
Thanks,
Have you tried instanced static mesh compoent?
You should be able to reach 10,000 just fine
I got to around 8000 without too much trouble 
4000 was cruising
Instanced static mesh component means that you are rendering all those 3D cubes (which can represent your data) in 1 draw call as they are considered as one actor.
Here’s a pic, where I created and attached actual 3D cubes to represent the 4000+ verticies of a complex rock (rock comes courtesy of UE4 demo cave)
