First time I see this being used the way they will be

"We also took the idea of ray tracing, not only to use it for visuals but also gameplay," Director of Engine Technology at id Software, Billy Khan, explains. "We can leverage it for things we haven't been able to do in the past, which is giving accurate hit detection. [In DOOM: The Dark Ages], we have complex materials, shaders, and surfaces."
"So when you fire your weapon, the heat detection would be able to tell if you're hitting a pixel that is leather sitting next to a pixel that is metal," Billy continues. "Before ray tracing, we couldn't distinguish between two pixels very easily, and we would pick one or the other because the materials were too complex. Ray tracing can do this on a per-pixel basis and showcase if you're hitting metal or even something that's fur. It makes the game more immersive, and you get that direct feedback as the player."
I think what this means is its removing the old ray-casting method with manually placed hitboxes and just uses the model geometry + materials. The ray will return the information that you've hit it and what the material. Probably a lot less complex to pull also than an artist making accurate hitboxes (99% of games have super simplified ones that don't even match the geometry).
Kinda neat.
I imagine like Indiana Jones that Doom Dark ages will require RT hardware. Or that even if there's a rasterized version without the eye candies, that the ray traced hitbox will remain. To be seen.
DOOM: The Dark Ages uses ray tracing to enhance gameplay, not just visuals
DOOM: The Dark Ages is on track to become one the best-looking games of 2025 thanks to DLSS 4 and Path Tracing. It's also using RT to enhance gameplay.
