There has long been the claim that CPUs (these days GPUs, but the claim predates GPUs) that can ray trace your games with plenty of frames are just around the corner. So far that hasn’t happened and most people working on CPUs/GPUs are pessimistic of it. Maybe you could raytrace something simple (tetris?) in real time, but modern games put in too many objects.
I’m sure a counter example exists, but I’ve been around for year and not seen it yet. Though I’ll accept that the exception probably exists.
