Watching this footage and I really just don't 'get' ray-tracing. The game itself looks stunning, but the reflections being a bit better just really doesn't seem like that much of an improvement. There was a brief clip of some tech demo where they turned the ray-tracing on and you could suddenly see the reflection of a fire on a car and I'm just... Is that really worth cutting your framerate in half for?
I dunno, I might feel differently when I get to play around with it in-game myself, but at the moment the 60fps mode just seems like an absolute no-brainer.
The same could be said about other graphical features we've seen over the years though. Technology improves. Graphics improve. Raytracing is still in its infancy and will only keep getting better while also becoming cheaper to use.
At the end of the day, yes it is
just reflections and might not be something you immediately notice or care about (though raytracing can also be used for shadows, ambient occlusion, global illumination, and also audio), but it does add to the overall cohesiveness of the image. There was a recent example where Miles was in a shop, and seeing civilians walking down the street via the reflections in the window, to seeing Miles/the shop owner and items for sale on the door's reflection was pretty neat even if it's not exactly important. It just makes the scene feel more complete.
For example:
Guy walking down the street behind Miles.
Girl looking back at Miles waving at her as she exits the store.
The shop owner reflecting in the door as he mops. Miles is later seen reflecting in the door too.
Pretty small stuff but something I think makes everything feel more grounded. Some of this you can do with other techniques (but with varying results), but raytracing will make it easier.
Having said all that, part of me is thinking I'll play it in the 60fps mode instead and leave the high end raytracing stuff for my PC haha. We'll see.
