The person you replied to mentioned a refund from Sony, so we can assume then that they got the PS4 version. Unfortunately, the last-gen console versions of the game were horrendously broken and had major performance problems. I don't blame people for being mad at CDPR for releasing the game on those platforms - the game was clearly not designed for the older platforms and the company took a lot of flak for releasing it on them.

I say all this as someone who has enjoyed the game immensely on PC - it's one of my favorite single player games of all time. It's just a shame that CDPR got greedy and tried to sell it on platforms that couldn't handle it.
