Digital Foundry did an analysis. It's a mixed bag, some games may look better, some worse. The core problem seems to be the new upscaling technology PSSR from Sony (for haters its pronounced like "pisser", oh I see in your other comment you are already aware of this lol).

Imagine paying a premium price of 800 Euros and then getting this. Fanboys will defend it no matter what, just like Apple fans defend if they purchase crap.

Yeah, it doesn't appear that PSSR (which I cannot help but pronounce with an added i) is the highest quality upscaling out there, combined with console gamers not having experienced FSR/FSR2/FSR3's uh, specialness is leading to people being confused why their faster console looks worse.

Hopefully Sony does something about the less than stellar quality in a PSSR2 or something relatively quickly, or they're going to burn a lot of goodwill around the whole concept, much like how FSR is pretty much considered pretty trash by PC gamers.
