Managed to render this at 14000 x 10500 on my 32 bit machine :nerd:

Wow this is a fantastic fractal and super quality. How can I render that size?

the best way would be to get a 64 bit machine with lots of memory and 7x 64 bit version or chaotica.

I did it with windows xp pro 32 bit by setting the /3gb switch in my boot.ini file, restarting in safe mode to free up as much memory as possible, and render using apo 2.09 which has large memory support enabled. Also, i had to render landscape instead of portrait for some reason :confused:

Thank you very much for your reply. I can forget about it then :D I don't dare to mess with the boot.ini file :D I have a pretty powerful machine 3.40 ghz i7-2600 multi core and 16368 mb Memory but the free chaotica version only supports around 1920x1920 pixel. The professional version costs 100$. Thank you for pointing out that 2.09 can handle larger format. I just checked how it compares to 7x 15b for a render of this simple flame

2.09 apo render would handle Size: 14000x10000, Quality: 5000, Oversample: 1, Filter: 0.6, Buffer depth: 32-bit integer, Allocating 2'145.03 Mb of memory
in 19 hrs. Oversample 2 would be too much even at Quality 1000. With apo 15b such a render is out of the question. The best render I ever got out of 15b so far was Size: 3000x4200, Quality: 5000, Oversample: 2, Filter: 0.6, Buffer depth: 32bit integer, Allocating 773.88 Mb of memory. That was a rare occasion. It would not do the above flame at these settings.

When I bought this pc it never occurred to me that a large,good quality render would depend on anything else but a lot of ram and a strong prozessor. I was very disappointed when I realized that apo sets the limit :D

without modifying the boot.ini file, apo 2.09 and 7x 32 bit have the same memory capabilities. if you try to render too much, they will both fail.

it sounds like you have a 64 bit machine and a large amount of memory. you should get the 64 bit version of 7x and you can easily render much bigger than me. Turn OS to 1 though, no use for it when you are rendering that big.

Strange I don't know how to manipulate a boot.ini file and still the 2.09 would accept a larger render format than 15b but of course who wants to wait 19hrs for a render to finish.. I tried the 64 bit version but if I remember right I could not use most of the plugins I like and could not see most of the old flames with it.

oh. i guess your OS has it enabled by default
