Yeah, I would not pay full price for this port either. I had a similar experience with Horizon earlier this year on PC. I bought it after someone posted an amazing RTGI video, and while the game looked really good on PC, I was really pissed by how poorly it scaled after 60 fps. I couldnt get the RTGI to work so figured id play it on 120 fps but while the game run fine at 4k 60 fps maxed out, it just wouldnt hit 120 fps even if i dropped the resolution to 1080p and settings to PS4 quality preset. You can probably find my posts on here bitching about it because i had already played it at 60 fps on my PS5 so all of a sudden the PC purchase felt like a waste without 120 fps.
Now on my 3080 I can of course brute force it, but at the time i was pretty pissed about it because other third party games ran fine at 1440p 120 fps. So trust me when I say I am sympathetic.
That said, i look at something like Doom and im like meh. The game doesnt look as good as Sonys first party titles. I know it has to run at 60 fps on base consoles, but i highly doubt it is being coded to the metal like say TLOU or Uncharted 4. If anything, the PS4 is being held back by the base xbox one specs.
