Nvidia can say they're going to break the laws of physics all they want. They're not going to though. It could be feasible for certain classes of games where the options for "what thing can the player do next" are very limited, but literally anything with analog controls just can't work like that.

im still very skeptical that predictive rollback is gonna feel very good to play with, ggpo is still probably the best existing version of rollback netcode and it still gets pretty fucky when it has to roll back

Well it won't work on games that are designed around the reflex of players. Unless they somehow provide an EEG on the primal motor cortex, which I would be very happy to see :-)
