The user is correct in that the modularity of a home PC is not the most efficient way for the electronics to communicate, and therefore some performance is lost.
I would also point out that while a PS5 has known, defined specs that a developer can plan for, a PC could be pretty much any specs. And while yes the dev can state a minimum spec requirement, but if they are launching on PC they are going to want to target a wide audience.
Long press is by far more annoying to me than the disguised loading screens.
