World-Machine 1.25 is all I use for terrains and it is already a Fantastic Tool that I would not trade for any of the others and I have tried the others.
World Machine Professional has been designed from the ground up to support massive multithreading. World Machine Professional is able to utilize up to 16 cores at once to provide the fastest views and builds possible. There are three massively-multithreaded areas in World Machine Pro. I will order my New Version next weekend. Can't wait to play with it!!!

 

I would rather be Politically Incorrect,
Then have Politically Correct-Incorrectness!!!
