couldn't resist trying the full muscle of the opencl-mode in mandelbulber ;D

full AO and volumetric fog  are turned on here @ 3072x2304
I like the cartoonesque style

A significant difference between cpu and cl mode seems to be the treatment of color palettes.
I mostly work with custom made palettes at color speeds of around 100. With theese settings the results are a complete different talk.
Rendering Time - 1:44h on a radeon 5770
estimated Time on a Phenom II x6 1055 - ~5h

have fun!

Definitely looks like some sort of synthetic and pliable substance is coated on, and holding together, the more firm but deteriorating rock like structures.     :D

Nice Image  reminds me of lichen structure. The fog effect has turned out well.

hmmm wonder if I can get opencl on my graphics card
feeling I maybe out of luck there.

nice one.  just out of curiosity, the tooltip for the AO quality value gives an example range of 1-30, by "full AO" do you mean you set this value to 30?  if i try using higher values there my mandelbulber crashes.  im not sure if that means i need more system memory or more video memory or what.  i have a 1gb nvidia 550 and 4gb system memory

also curious if you could post a comparison pic (could be low res render) just to compare the difference between cl and cpu rendering.  i cant even do cpu rendering on my old athlon 2 core, if cl mode takes 1.5 hours then trying the same settings in cpu mode says it will take 5000 hours, i tried letting it run overnight once and it got to 1% and the ETA was still steadily climbing,   :o

Thanks a lot people appreciate your interrest.
@alij: why should you be out of luck? Buddhi is working on nVidia compatibility and I'm sure he'll succeed soon.

@quaz0r: no, full ao means real ao - neither screenspace ao nor fastmode ao. Normally I use quality 5 for ao. It's the best compromise between quality and rendering time.
a comparison pic is attached here: http://www.fractalforums.com/releases-b233/mandelbulber-1-17-opencl/msg66038/#msg66038 (http://www.fractalforums.com/releases-b233/mandelbulber-1-17-opencl/msg66038/#msg66038)

Hi I'm all a bit tangled up with debian OS I will take some time out to see if I can get it installed
There are a few gpu rendering things I would like to try  :)
nice comparison pics

Man this shouldn't be a problem. Afaik Buddhi's favorite os is debian - in most cases bug reporting grants you some support...
