I've no idea why or even how people encounter such issues, but most of the time these seem exaggerated - I guess people with issues tend to be report matters more actively. With that said, I did have issues in RDR2, where the performance tanks in a linear fashion the longer you play, couldn't find a workaround. Restarting the game helped as a temporary relief, but it was annoying regardless. Otherwise, it's been smooth across the board.
I have a full ayyymd-build, so your mileage may vary. But you can't really know how things pan out without trying, can you.
