Quote - I tried some - no scene just added clouds, 640x480 final.
My pleasure to say I have no problems with that. Very similar to Gill's results:
no clouds 11"
Dark Cumulus (spectral 2) 2'38"
Swirly cumulus (volumetric) 12"
Large cummulus 2 (spectral 1) 47"

I hope they sort it for you - good luck!

Hi,

I will note your results and send to them as I do at the end of the week from other sites as well. If you would not mind, could you do the tutorial link in my first post at "geekatplay.com" and post your render times with that file? That would help because if you see MUCH better speeds than myself on your Macbook then obviously it has to be something funky with my Mac hardware, be it graphics card or otherwise.

Right now I am strongly leaning to the 8800GT being the culprit as I have yet to hear from anyone with that same card, especially on a 2008 Mac Pro. I know there was some issue with NVIDIA in the Mac notebooks but nothing that pointed to Mac Pro graphics cards. We are still trying to narrow it down more but if you have success with your hardware then I will certainly pass that along.

Also, can you confirm the model year of your Macbook and OS version?

Thanks for letting me know, hope it gives us some more clues.

Jeff
