I would like to add that the way movies use raytracing (usually called path tracing in that context) is very different from how games use raytracing. While animated movies will simulate every ray of light to create the entire image, games use raytracing typically only for reflections and global illumination, while the rest of the image is still rendered using traditional techniques. (I'm no expert, though I have spent a bunch of time using Blender and playing around with Minecraft Raytracing mods)

Yeah, I think the Quake II RTX version uses it to completely render the scene. That's about the level of graphics we're at for whole scene path tracing.

RT is in a PS1 era right now. We're like 15 years from games having modern graphics (by today's standards) and fully pathtraced.
