It is easier. Raster based rendering does a lot of cheats to make it look realistic that the devs have to come up with and write. To do 4K you need to calculate over 8 million rays and their bounces. Very processor intensive, but much simpler from a programming point of view.
Now the difference between some of those settings on low and ultra are not really worth it is some cases as they look basicly the same.
Overall these ray tracing methods are leading to more realistic raster based rendering as the devs can actively see the “problem” areas and make or fix the cheats to look better.
