General FAQ

See this page for rendering-related questions.

  • Does Chaotica support GPU acceleration?

    Chaotica currently uses a (highly optimised) CPU-based rendering engine; however, OpenCL support is planned for the future, so that all GPUs can be used to accelerate rendering.

  • I've upgraded my computer, how do I request a new licence key?

    Send an email with your order number to using your registered email address.

  • Why do some plugins not work?

    Most plugins available are 32bit. Make sure to use the 32bit version of Chaotica with them.

  • Why is my computer running hot / at 100% usage?

    Fractal rendering is a processor-intensive task, and Chaotica is optimised to make the most of your computer's available resources. This means full use of all processor cores.

    If your computer is older and perhaps dusty, this continuous strain can generate excessive heat compared to short, simple tasks such as loading a web page.

  • Why does the 32bit Windows version of Chaotica run out of memory when I have plenty available?

    32bit Windows programs are limited to at most 3GB of memory, even when specially compiled to be "Large Address Aware" as Chaotica is on this platform. In practice less memory is available, according to some sources as little as 2.2GB. However, this is still much better than the ~1GB allocation limit without this option.

    We strongly recommend rendering with the 64bit version of Chaotica if you are looking to make large images.
