Before The Sims, I used to play with this program that was meant for architects designing homes, but 9-year-old me treated it like a game. It had a ray tracing button that when pressed, would render a ray-traced view of the room you were in.
It took at least a couple of minutes on my dad’s Windows 95 PC to render a single frame, and if you moved the camera at all, the view would switch back to raster and you had to re-render the scene all over again. But it was real ray tracing, performed on the CPU, in the 90s.

Ummm…ray tracing was invented for CPUs long before GPUs even existed.
