It's a lighting technique that creates more realistic visuals, especially reflections.

The technique allows the GPU to "track" / calculate how the light should actually travel and what it bounces off of (like light in real life), compared to the pre-calculated methods of before.

So it will cost you processing power and therefore frames, but it greatly increases the visual accuracy of lighting, shadows and reflections.

A simple but effective example is Minecraft with Ray Tracing. The following video showcases the difference:

Notice how the game looks completely different. That's what lighting can do for a game.

Obviously this is less noticeable when it's a game with realistic graphics and a lot of time spent on getting the (prebaked) lighting just right.
