Is ray tracing catching on?

Source: Francis Damm   It was late July 2018, when Nvidia surprised and delighted the world with the introduction of its RTX GPU that could deliver real-time ray tracing, dubbed RTRT. If you build it, will they come? It was a gamble. Nvidia had to not only design and manufacture the chip, but they also had to build a toolset to exploit it and then sell the idea to game developers—a lot of game developers—hoping one or two would take it up in time to match Nvidia’s release date. The initial games were basically patches or lucky last-minute post hacks.
