Have a look at the game Control. I think this is a game where I feel they've used the technology really well. Maybe the office building location is a good one for raytracing, as it's full of reflective surfaces, but the graphics feel substantially better with it switched on. Remedy Games also managed to maintain a reasonable framerate with lower end RTX hardware. Other games look less impressive, however, such as minor changes in the shadows. It obviously requires some thought before it can be used.
