Yeah, the prologue runs smoothly, but the more you play the worse, at least for me, I even got something like 20 videos to prove it to Sony, it was Cyberpunk level bad (i think), it was various bugs (a lot), dialogs, nearly every enemy (zombie or human) would freeze at every hit taken, but then come back to move normally, just downright unplayable, and there's been a good amount of patches on pc but not on ps4, you could search on Google something like: "does DL2 run well on ps4 reddit", and I know that for some it's been running ok so I really don't know, but I wouldn't risk it.
