alt Hacker NewsNot disagreeing with you about lighting, but there is a differnce in older games that make RT optional. They use RT as a "ultra high quality" shadows/reflection graphical option. So there's no point of having a high performant, low quality RT option.
This isn't the case with games that require RT. Doom Dark Ages can even run the RT entirely in software, implemented in AMD's Linux drivers: https://youtu.be/R5G2bYiA1hk
So I think it's fine to ignore benchmarks that mention RT, meaning it's basically testing the game at "ultra quality" settings.

Running RT in Software doesn't mean it's free, it just draws the performance penalty from the rest of the system.
And the demo in the youtube link you shared shows this. Like sure, it's playable, but it looks like game from 2009. It looks fine for playing on a small handheld device like the steam deck, but not on a 27"-60" monitor/TV.
