The new Metro game is quite impressive. Very playable with all the settings maxed at 3440x1440 and having RT on makes a pretty big difference with the lighting. I think this is the first game that really helps showcase ray tracing, it was more subtle in BFV. Some screens I took...

This is a good showcase on what the raytraced lighting can do. We are so used how games are faking lighting and shadows that we don't notice it. With RT off some things look like the lighting is flat in areas and objects can look like they are floating above things instead of being on top of things.
