Most games on the new consoles have to drop the resolution below native 4K to achieve 60fps and sometimes even 30fps depending on the game. Yet, they call it dynamic 4K because its being scaled to 4K. I agree that no reviewer should equate DLSS with native 4K, but its also not the same as just running at 1440p or some lower resolution either. What DLSS offers is better performance with lower quality loss than just dropping the resolution down. And it works most of the time quite well. I don't think Nvidia is being deceptive here, they have been quite forthcoming with what DLSS actually is and some games even show you the rendering resolution vs the scaling resolution.
The bottom line is no GPU available, console or otherwise is truly capable of running all the latest technology at 4K or even 1440p at that matter. RT, from what I have seen, is actually less of a hit in most games than going from 1080p to 4K resolution, but its not far behind. Running games at 4K is a major hit on performance compared to 1080p, just look at the numbers above in every game its greater than 50% reduction in frame rates, while 1440p is about 15-30% drop in frames depending on the game. The purpose of DLSS is to give better quality than simply lowering the resolution for better performance. Sometimes it works great, other times not so great, but right now its the only way to get '4K' with High RT at a playable framerate. The consoles are already struggling with native 4K with the minimum RT and 30fps, to get to 60fps requires RT off and dynamic resolution scaling which has been shown to dip under 1440p at times depending on the game. By the end of this console generation GPUs will be pulling off RT and 4K with ease, but we're just not there yet, they'll need to be at least 2X as powerful as the RTX 3080 and 3X if we're being honest.
