I'll see when I play it someday (maybe because of this performance), but that's a pretty tough claim that it's doing stuff far beyond even the best looking & most demanding games on the market, because there are no games on the market that run as bad as this at 1080p and from what I've seen of QB it's not the best looking game ever made.
I think at the moment it's the most advanced game technically yet.
The lighting is second to none. Everything you char does seems grounded because of how the gi is dynamic, even for very mundane tasks like opening a door, or even having the entire scenery changing in front of you while the light always feels correct.
The asset quality, speaking of both modelling and texturing is also top notch. You'll see tons of really fine details like even npcs having eyelashes or modelled screws on their armor (that even reflect everything).
And then there's the post processing. Everything is so clean and so movie like that some effects are actually better done in game than in the series like the time shattering, which is by itself an spectacle, when you are dashing through deforming everything (and the lighting properly changing to that deformation).
Throw in tons of volumetric lights and particles and it's really hard not to be in awe when this game moves.
