I haven’t played the finals myself but as of the pre-release version when I watched a video about it lighting didn’t update at all without raytracing enabled. It is pretty hard to get any sort of dynamic lighting without raytracing. If not impossible, depending on how you define raytracing. But basically if they have a dynamic lighting feature that works without ‘raytracing’ they have to create a whole other GI system using world-space probes and maybe even dynamically voxeliIng the entire scene. Neither of which are easy on performance, but usually not as bad as normal hardware RT and restir. Neither of those are good at reflections or fine detail, which is why games that want to look better than that usually switch to doing it the normal way.
It says on that page that SHaRC requires raytracing capable hardware. I guess they could be modifying it to use their own software raytracing implementation. In any case it’s the exact same math for either hardware or software raytracing, hardware is just a bit faster. Unless you do what lumen did and use a voxel scene for software raytracing.
The Finals uses rxgti and the only difference between raytracing off and on is the speed at which the lighting changes within a scene.
I see little benefit from raytracing in many games. And would prefer the implementation be used in other games.

I think they’re using the SHaRC implementation in RXGI for when you disable raytracing.
They’re forthcoming about using rxgi. That said it does work very well even on non-raytracing capable hardware.
