The article doesn’t offer an explanation, but to opine: 9th gen consoles are very memory optimized. Beyond their GDDR6 or equivalent RAM, they also have ultra fast NVMe storage drives (which you cannot assume a PC will have when porting) that can carry some of the weight you would formerly expect RAM to carry.
Is there a technical reason that this is needed or do the devs just not optimize the games well?
