This is why we should never take any of these comparisons seriously. Neither system has been used effeciently, all these games are running previous generation code without any next gen features.
It is like arguing for AC black flag on ps4/xbox one and having unity the year after.
Well if they are at the same res and details or no obvious bc limitation, we can get an idea of how they perform across different engines comparatively.
Its more these big differences only based on last gen bc limitations that people run with.
Some in this thread making out the ps5 is using CB rendering because it cant handle more res, despite being proven wrong countless times in ither comparisons.
For eg like the one x and pro versions or even people saying ps5 games run higher res on older ps4 games that didn't get a one x patch. Yes they run better but its a bc limitation. Not hardware obviously.
Ps5 has suffered the opposite of that example from the pro versions without always the ability to easily up res etc without a patch which in this climate devs would rather not do.
Still though there's enough examples of the direction of where these consoles land, trading blows, PS5 having less issues and smoother framerates overall.
There have been some decent cross gen ports, not fully advantage of either but gives us an idea.
