This is BIG News !

Fractal Architect 4  now fully supports Metal GPU rendering on all Macs built since 2012 (using the Mac’s Intel GPU). Version 4.3.3 of FA 4 has some critical fixes.

Last October, we reported issues with Metal rendering. Those issues have been resolved in version 4.3.3 of Fractal Architect 4.

With the latest Sierra Beta, OpenCL GPU rendering now works on Intel GPUs for the first time too.

The rendering performance increase is HUGE.
