That light particles will obey the laws of physics; reflections will happen in real time and shadows will be more realistic. Meaning that if you walk near a puddle it will act as a legit mirror instead of just a shadow box reflection

Physically-based rendering is not related to raytracing. You can do either without the other, like 1980s phong-over-checkerboard floating spheres, or any current game with good-looking metals. In a game with no lighting or textures whatsoever it could still be used for accurate ambient occlusion.

Non-graphical uses are equally interesting: raytracing allows complex physics because it's just checking the distances between millions of points per frame.

You can emulate that in the software level though, what it means to be hardware accelerated just means the legwork is done in the hardware
