Lecture 13: Global Illumination & Path Tracing (105)

What would happen if we sampled more than 1 paths at every bounce? So for example once we determine the intersection point, can we instead of sampling the radiance from one random direction, sample from 2 random directions and take an average? Would this help reduce noise? What would the impact on performance be since the ray being traced will recursively grow?

This certainly would reduce noise, but I'm unsure as to whether or not this would perform better than sending out 2 sample rays to begin with?
