I thought Unity/Unreal/Eevee were Rasterization engines!?

Why Is Nvidia/Unity promoting real time raytracing in their game if its a rasterization renderer?

Are they using a hybrid process and if so what parts are for raytracing (shadows, reflections)?

Please clarify it for me.

They are using a hybrid, overlaying the shadow and reflection layers on top of the primarily rasterized scene.

Nvidia are currently pumping pure, unadulterated hype right into the media. At the moment, it’s a gimmick, but give it a couple generations to mature and it could be really interesting tech.
