Motion blur
Supports deformation motion blur for geometry, particle and spline systems (for hair and fur);
Supports trajectory motion blur for geometry, particles, splines, emitters and cameras;

Helps to calculate the correct refractions in the eyes of the character;
Helps to calculate surface and volumetric caustics: a pattern of light on the bottom of a pool or God rays in the Ocean.

Emitter Adaptation
Allows you to use millions of light emitters in the scene;
Helps to get a picture with less noise.

Adaptive image sampling
Prioritizes pixels based on their noise and brightness;
