I can see the difference in all of those. I can even see the difference between 120hz and 240hz, and now I play on 240hz.

Ray tracing looks almost indistinguishable from really good rasterized lighting in MOST conditions. In scenes with high amounts of gloss and reflections, it's a little more pronounced. A little.

From my perspective, you're getting, like, a 5% improvement in only one specific aspect of graphics in exchange for a 200% cost.

It's just not worth it.
