Drinking Fountain 1
My computer is even worse. It crashes around 1 to 1.5mil polys. Since my trees are particle trees, I can have hundreds of trees in my scene without any issues. Also, I'll be using instancing alot too so I should be ok. I plan on getting a better computer in the next 1-2 years so I don't think I'll have any problems.

Don't be satisfied with what you can do but rather strive to do the things you can't do!
