Sony exclusives usually run really badly on pc, just look at GoW, it ran on base ps4 in 1080p30, yet look how much it needs on pc ps4 alike settings for same 1080p30
Compare performance in fair cases- aka multiplats, where they arent specifically made for ps4 then ported halfassedly with increased requirements to pc platform
Edit: Here proof how fucked up performance pc port of GoW has on pc, running on 750ti, for a very long time equivalent of ps4 gpu, if it wasnt close at stock clocks, it was if oced.
Yet here, with super strong cpu(that is actually much faster from ps5 cpu), it runs in single digits on 1080p low(so settings lower than ps4 base ran at)
On the other hand here fair comparision ps4 vs 750ti(with old i3 cpu nonetheles), witcher3, so top dev, good graphics, not some indie dev, DF vid so u can see where exactly dips happen
