@Quadraxas i have informed myself about unlimited detail.
I typed it in in Google here is a quote of the page
Fig 1.1 showed a tree base from one of today’s games with 3 flat sides, Fig 1.3 shows a tree base made on Unlimited Detail with 300,000 flat sides, the polygon tree needs special high powered graphics cards and multi-core computers to run it.
The Unlimited Detail tree will run on anything from a PC to a mobile phone and no special graphics cards are needed. (See Fig 1.4)and here is a link
