The GPU is a relative new name for the processing unit on the graphics (display) card. Modern GPUs actually contain very powerful computers, although the architecture of these computers is very different than the main CPU. It is possible, though quite difficult, to use these for raytracing.
Use of the GPU for path tracing is not a panacea. It's technically very difficult and likely to only benefit those with very fast, expensive, GPUs. I could easily spend months working on it and have it be slower than CPU rendering for most users. It is an area we're watching.
Maybe it's time to look more seriously at the possibility to engage GPU in rendering process somehow Roy, isn't it? Now, all this power is just sitting inside our machines without any "substantial" benefits (maybe except some occasional gaming once a year :) )
Lots of lights. This is a pretty challenging one for the Path Tracer.

Hey, I`ve been working on this project, and i succesfully create a nice night view, I`m very happy with it, but i have a question, this render took 183:17:33 hours and 2583 passes and the quality still needs a few thousands of passes, somebody knows why it took so long I mean I just put some spotlights and omnilights inside the houses, do you think is the water texture? this is my pc configuration:
windows xp profesional sp3 Intel core i7 860 2.8ghz 4gb RAM
"Since there is no Ambient Occlusion Slot in 'Texture Set' Mode of the nXt-Material Editor,
I found another way around what to do with AO Maps:
Baking it into Diffuse; e.g. Multiplying AO Map over Diffuse/Albedo/Colour in…"
"The wooden texture of the TV-Console looks quite decent.
The Wallpaper on the left has an interesting structure, maybe it would look even better, if you make the texture seamless + applying a little bit of depth, e. g. with highpass - filter in PS?"
"Thank you for help on this topic!
Will test 'Automesher LT' (developed by Automapki), if I run into troubles again.
[Sometimes I was wondering about, if this forum is still alive... .]"
"Good day,
I searched the former forum posts and found another option to solve this problem which is another plugin to autocad-----AUTOMAPKI. You can give it a try."
