You perhaps already said this before but my memory is failing me... you render on a quadcore machine? Do you use the multicore capabilities of the new Terragen-Build or are you rendering the image partially by using the Windows Task Manager (like you explained to me, thx again!)?
As you are rendering the image that big, I perhaps take the awesome tree in the foreground as a fullscreen desktop background
Right now, I still have my invidious Joker staring at me (image from my last thread) but perhaps there will come a time when he chases me in my dreams
then I will switch to something nicer
