3D graphics were incredibly primitive back then. There really weren't "3D processors" as we know them today.
On top of that, CRTs masked many of the weirdest graphical artifacts - the shimmering we see on modern screens was much more of a blur on screens at the time.
It's fun to look back at the PlayStation and the N64, and to see how each of them handled limitations in a different way.
When I worked at a car insurance company, we had two vendors who shared names with competing insurance companies. It was funny.
