semantics, whatever the limitation is OpenSimulator can't update the viewer with more than about 1000 objects, I do all of my tests locally on 1000Mbit network, so if thats not enough what is? maybe I need 10TB network?
Not semantics, accuracy matters when you’re placing blame on the wrong components. The fact that you even see objects rubberbanding is enough to know the viewer is capable of rendering those scenes. It’s trying to predict where that object is going when it hasn’t received that object’s next update. I can rez 3,500 objects in Second Life before seeing this behavior. It’s far lower in OpenSim because the HTTP/UDP server is crap. Convenient, but none-the-less crap under load.

Naturally, you aren’t going to see people rezzing 3,500 balls and dropping them in a real world scenario, but you may have 10,000 physical but not actively thrown around objects in a scene, and bullet sim is less than happy when this happens.
