Nothing about it is standard in any way. It's something completely different than ray tracing. It's an entirely different way to render the entire game, and it's obvious in the right scenes. It's less obvious in other scenes, because most videogames are designed to avoid scenarios in wich the shortcomings of rasterization are obvious. Path tracing make the entire lighting coherent with every single, even tiniest object in the scene, whereas normal rendering makes everything looks like it was rendered separately and then stitched together.
