Irrlicht Engine

I think everyone can guess that was me, forgot to login

Yea 5000 nodes is alot and the ammount was just to stresstest the engine, and it clearly pointed out the main problems :) The idea is that 5000 randomly positioned nodes in such a small space will occlude eachother alot. With correct culling this could still be possible, of course calculating ...

I quickly checked IrrlichtNX changelogs and it seems it has sphere vs frustrum and sphere vs cone culling. So it's a bit faster but the core problem still remains, I haven't heard of Nebula before
