03 / THE INFINITY ENGINE
More speed.
Deeper zooms.
The new Infinity Engine delivers dramatically improved Mandelbrot rendering performance and deeper zooms. Version 3 extends the validated zoom range from 10¹⁶× to 10²⁵×: a billion-fold increase in magnification.
Apple’s Metal GPU handles the heavy pixel calculations, making deep exploration faster. Adaptive precision brings finer structures into view as you zoom. Useful detail and render time depend on the scene, settings, and device.
