~sigh~  

What I MEANT is it can't be done via HIS method with only 2-4g of ram WITHOUT using billboards/rendering in layers & compositing.  I have done quite complex images as well with what I have - BUT I use billboards & composite in layers if need be & not just in Vue either.  Simple as that.

If you only have 4g & under you will have to use these methods. And just having 64x bit OS won't make that much of a difference UNLESS you have the extra ram to go along with it :)
