For me A8 goes down the drain when working with MANY entities.
The number of triangles does not matter that much anymore (speaking of ~100 triangles per entity).... but beyond 5000 entities visible at the same time it gets frustratingly slow...
It probably creates too much draw calls then. I dont know much about the insides how it renders, since I cant see the source code of the engine. But to speed things up it has to batch those items. Polygons in the view frustum sharing the same material could be sent all at once to the graphics card as an example.
But another problem can be the entity database. Maybe looking up these thousands of entities is just too slow.
