I am no fan of nVidia, but yes, rasterization is a hack. I like to call raster GPUs overglorified sprite rotoscalers. Every little thing that light does in reality, except perspective, needs to be painstakingly implemented in dedicated code. Path tracing is much closer to just modeling what light does, and all the optical phenomena fall out of it naturally.
