As a sibling post already mentioned, rasterization based hacks are incapable of getting as accurate lighting as path tracing can, given enough processing time.

As a sibling post already mentioned, rasterization based hacks are incapable of getting as accurate lighting as path tracing can, given enough processing time. I will admit that I was a bit sly in that I omitted the word "realtime" from the path tracing part of my claim on purpose. The amount of denoising that is currently required doesn't excite me either, from a theoretical purity standpoint. My sincere hope is that there is still a feasible path to a much higher ray count (maybe ~100x) and much less denoising. But that is really the allure of path tracing: a basic implementation is at the same time much simpler and more principled than any rasterization based approximation of global illumination can ever be.
