So much ray tracing eye candy was promised that I reckon the game's own backed lighting can easily be confused for some of that feature.
"ray traced lighting" barely seems to justify the price. Looking at this:
Overall the image already looks impressive without that effect, and the effect itself can be easily confused if you don't reckon where the light source is. If you want to look with a critic's eye, ray tracing needs a lot more horse power than these cards provide in this aspect, and the little impact just shows the flaws of the added effect itself.
A tint of gray that appears in a corner, or that little gray shade on the boxes is kind of relative. If the box is shinier or cleaner, it does appear brighter by itself.
Lights were backed in the scene by the developer, so it is their expression, and a few effects don't seem to justify the price and the marketing this generation. if is a matter of taste, and not of necessity, any eye candy is welcomed, though.
PS. The game is available on GeForce Now service.
