Control was one of the first big games to come out after Nvidia’s first line of GPUs with raytracing hardware (RTX 20xx) and one of the first games to use those hardware features. That’s why it was used as a showcase (there was probably a deal between Remedy and nvidia to make this happen, not sure).

It was a good looking game at the time, but remember it originally came out on PS4/Xbox One and that version did NOT have raytracing.
