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!

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. Title: Re: get a grip Post by: quaz0r on September 19, 2013, 05:32:35 PM 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 Title: Re: get a grip Post by: taurus on September 19, 2013, 07:58:37 PM 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) or here: (http://www.fractalforums.com/index.php?action=dlattach;topic=17149.0;attach=9311;image) Title: Re: get a grip Post by: alij on September 19, 2013, 08:05:50 PM 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 Title: Re: get a grip Post by: mclarekin on September 20, 2013, 01:57:11 AM Informative, I watch with great interest, I may even try it out :) :) :)

Afaik Buddhi's favorite os is debian - in most cases bug reporting grants you some support... |
