I'm not a console fan on either side. So much for uneducated guesses. I'd imagine if you haven't realized what the comparison is conveying, then I don't know what to tell you at this point, especially as you have failed to understand it after all these pages still.
It's about the ps5 cpu, and how it isn't holding up to par compared to weak PC hardware. You can blame it on compatibility mode all you want, but it won't change anything. As matter a fact, you should blame Sony for it's implementation of BC, at the very minimum. The devs can only update their games based on hardware profiles, which are determined by Sony, as they mandate these things.
Either way, the performance is really bad. And I'm sure it would trigger you, especially as you constantly shitted on PC platform over the past year, only to end up looking foolish after every comparison made with PC. I don't blame you though, I'd be upset if I was completely wrong on all accords. Maybe there's hope for cache scrubbers and ssd bandwidth this year? Or next? Who knows, but we can't base then from your assumptions, as we may end up looking like you right now.
Not all Sony fans are like this, it's mostly the warriors and the die hard fanboys. I have no problem with the fans, just not the die hard fanatics. Hopefully more comparisons like this come out over the next few days/weeks/months/years, so we can see what secret sauces come to life or lack thereof.
