It isn't exactly meaningless. Nvidia having deals with certain games can lead to AMD cards running games very poorly. WB and Namco are just publishers to distribute physical copies, whatever. Microsoft owns the Xbox brand and they would certainly have a vested interest in, say, making the PC version not look too much better than on their console.
So Microsoft pay to "downgrade" PC graphic while Nvidia pay to "downgrade" AMD graphic that are used by consoles. CDPR Just take the moniez and "downgrade" graphics everywhere. Make sense.
