Awesome Scene
About benchmarks:
Dual xeon 4 or 6 cores are far the faster CPU renderers. They become even faster on high resolutions. (64 threads opt is needed).
On a tree texture node setup, I noticed a mix of transparent + translucent, mix set to 1!!! So, delete transparent node. And gain ~40% of render time LOL

OK, it finally finished! Given the config. of my machine, I’m amazed!
Rendered with Blender 2.62.0 r44136
on: -Intel Core 2 Duo E7200 @2.53GHz
-2GB DDR2 RAM @1066MHz

No settings changed. Mem: 102.9M (221.5M)
Render time: 58min 22sec
Oh, the end result…
Incredible! Not going to try to render, my machine would die if I tried to load the .blend. Did you generate the trees and landscape in blender or in another program?
Do you remember what settings you used within ANT landscape? Just a type and a basis of the noise.
Thanks
Edit: I tried your little script, but…it doesn’t work like I would wanted to. I thought you painted some of the vertex by hand so I tested it. I deleted vertex group you made with height mapping and try running the script again on your landscape and it was just the way you saved it. I don’t understand.
Is there supposed to be some specific relation between flat surfaces and cliffs?
OK, it works. But there is one condition. Landscape size must be set to 300 or more.
What is your powersupply? Mine has 750 Watts which is already overkill but otherwise I can’t think of a bottleneck of your GPU. Another thing might be that too manny programs are running in the background while benchmarking. Try restarting and then benchmark without doing anything else.

BTW I did a test with my overclocked GTX 570 shader @875 and memory@2000 the time was 3 min 1 sec!!! -> Amazing!
my results:

building BVH structure took 2.26 so pure pathtracing and compositing took 1.56
definitely I need to upgrade cpu & mb
thanks for sharing!

took 7min 48 seconds on a phenom II x6 on a Linux box. would love to try with my 5850 but you know how it is. I have 16 gigs of ram so I might try throwing in some more tree models just to add more variance (also might darken the cliff face and add a rockier shoreline, just to make it more like home) will post results…

I was very surprised that the GPU on Linux was actually faster than on Windows, seeing as the drivers are generally better on Windows! Maybe it has to do with the different builds…
Awesome scene! Looks great 
Best Nature in Blender imho. Great! And thanks for sharing how-to.

When I see renders like this its all worth it! 500MB AT 19 BILLION AWESOME!!!
The atmosphere is amazing!
You Rock Man:) This file is brilliant, I tried for this several times with stuff like this, but failed. I learned a lot from your file… thanks for sharing:
One quick note my trees are only like five polys each, they’re planes with a splotchy to transparent green material at different angles, so I don’t know if you needed all those polys at that distance, but it’s still brillian overall effect (beats my lame composition anyway) Thanks for sharing:)
Very nice and interesting.
Here are my benchmarks on Windows 7 x64 :

GPU (GTX 580) 02.55.41
700w power supply.
I am dual screening. I am going to shut my secondary monitor off and see if that helps

Hi, regarding your question, nope, i’m running on windows 7 the 2.62 official build.
cheers
wonderful test - art of optimizing the scene
would u share some tricks?
