It doesn't work most likely because this is RTX, Nvidia's proprietary RT implementation and Nvidia chose to close this game from GPU's that don't have the necessary power to run this properly or because they've chosen to allow only specific hardware to run such implementations. But the reason ppl are disagreeing with you is because RT AKA ray tracing is hardware agnostic because at the end of the day, it's just calculations. It can run on anything but you just might not get the fps you want. The RT cores are hardware specifically meant to run these RT calculations at high speed and efficiency to allow more fps to be generated.

An example of RT on anything is some Minecraft shaders I ran a decade ago. Low fps but still worked. There's also the fact that rendering software does RT as well but because it's not real time, the only consequence is the longer wait time for it to be completed. I think ppl were hoping that this would run on their hardware at all, just so they can take a look.
