With some games, pre baking lighting just isn’t possible, or will clearly show when some large objects start moving.
Ray tracing opens up whole new options for visual style that wouldn’t really be possible (aka would probably look like those low effort unity games you see) without it. So far this hasn’t really been taken advantage of since level designers are used to being limited by the problems that come with rasterization, and we’re just starting to see games come out that only support rt (and therefore don’t need to worry about looking good without it)
See the tiny glade graphics talk as an example, it shows both what can be done with rt and the advantages/disadvantages of taking a hardware vs software rt approach.
