Largest amount of moving multi-sprite prefab game objects VS 3D objects you've been able to manage?

after having the unity editor freeze and crash my PC recently for a couple of my tests I was wondering how many objects you’ve managed to get moving with sprite renderers and when did your FPS start dropping VS 3D objects.

I know unity can handle up to 10,000 3d objects.

Not so sure about the average 2d sprite rendered objects (or 3d objects that just have a 2d projection texture of a surface containing a sprite, not 100% sure what unity sprites are.)

Unity doesnt provide you with much automated scene management , basicly you need to do that yourself. I suggest that you look into object pooling and generating meshes instead of using alot of gameobjects for tiles and such.

This is however all part of the final optimizations of a game so its fine to start you prototyping with whatever unity gives you.

meshes?
