It feels like it wasn’t that long ago when I first started working with 3D rendering, and ray-tracing was something that took many minutes to render a single 640x480 image. I couldn’t have imagined doing that* in frames-per-second (and in higher definition, no less). Blows me away.
*Well, some of that - these are only raytracing certain elements, i.e. the shadows and reflections, not everything. But still.
