Grass is the fault of it for not having motion vectors.
So you actually went with this being the grasses fault despite it looking fine on TAA? Holy shit.
Apply your own logic remember
"DLSS on = grass issue"
"TAA = no grass issue"
So it's the "no montion vectors on grass" on PS5 Pro too, correct? Or is it the headline "PSSR has problems" in the exact same scenario and result for DLSS for some reason?
As for cyberpunk you need to lower settings not go high. That happens with low raytracing samples, res, fps. PS5 pro isn't doing full path tracing in a million years so I'm not sure why you think this would be the like for like situation to replicate a similar issue I'm referring to. You would need to replicate the settings of the users who ran into shimmering problems when they enabled DLSS so set 1080p, go low res, not path traced and max out settings. Ideally you would even need to go with the same build of DLSS and game for a fully controlled test.
Despite the claim that there were never similar issues though cyberpunk exhibited these issues when DLSS was enabled and RR got rid of a lot of the issues you see with the flicker, glint and noise. You can do things for better temporal stability but it often adds things like ghosting instead where objects that are moving blur, sometimes into non existence.
Notice the moving light gets blurred from prior frame info that results in the moving light not showing at all on DLSS. The film noise is far less noticeable than this.
Again introducing softness and ghosting for temporal stability to remove glints
And the artifacts of the improved temporal stability :
I could understand if you equally mentioned that these issues in the game were not DLSS/PSSR related for both but you don't do this. You're happy to blame blurred grass on PSSR, happy to blame specular noise and glints on PSSR but these are always somehow distanced from DLSS for you.
The claim that DLSS doesn't/didn't have similar minor issues is simply false though. These artifacts do not take away from the fact that DLSS/PSSR gives you considerable performance boosts despite these minor artifacts. In the case of DG2 it's nitpicking at best. It's far better with PSSR on the Pro. Despite the blurrier grass on PSSR/DLSS. The higher temporal stability of the default favoured the ghosting.
