Fractal Architect 4 Help Index

Hardware & Software Requirements

Applies to:FAFA 3DFA 3D-AV

Fractal Architect for Mac requires Mac Lion version 10.7.x or greater. It requires an Intel CPU in your Mac.

Optional Retina Display HiDPI Rendering

Optional rendering of all thumbnails and document previews using 2X HiDPI resolution (only on Macs with Retina display).

The default setting on Macs with Retina displays is Standard resolution as the image improvement from HiDPI resolution is barely noticeable with most fractals.

Rendering a 2X HiDPI image does take 4 times longer than standard resolution rendering. This performance degradation is normal and can be avoided by choosing the Standard resolution.

OpenCL CPU Based Rendering - Lion, Mountain Lion, & Mavericks

Fractal Architect uses a builtin OpenCL renderer that uses the CPU as the default renderer for the application. With CPU based rendering, Fractal Architect works on any Intel-based Mac regardless of GPU manufacturer. This configuration works on any ATI, Intel, or NVida GPU.

OpenCL GPU Accelerated Rendering on Lion, Mountain Lion & Mavericks

Fractal Architect’s OpenCL renderer can target a GPU on the Mac. An OpenCL capable GPU must be present on the system.

Which Macs have a GPU with OpenCL support?

Older Macs often have discrete GPU’s that are not supported by OpenCl. The supported GPUs can be found here: Supported GPUs for OpenCL

Intel SandyBridge CPU/GPU (2011 - 2012) processors and early Intel integrated graphics do not support OpenCL on its HD 3000 GPU.
Intel IvyBridge CPU/GPU (2012 –2013) processors provide OpenCL support for its HD 4000 GPU only on OS X Mavericks.
Intel Haswell CPU/GPU (2013 +) processors provide OpenCL support for its HD 5000 GPU only on OS X Mavericks.
