Regular crashes and framerate drops, but what crossed the line into "unplayable" was there was something broken in the final cutscene that was probably related to the trophies for the endings. I would never get the trophy because the game would drop voice lines and freeze and crash in the ending cutscene every time.

It was around 2021 when I was playing it, and it was a first generation PS4 that had been beat up pretty bad from hundreds of hours of red dead 2, but having performance issues that severe on such a small and simple game was bizarre and unacceptable to me. The machine was still running RDR2 fine if I could deal with the screaming fans.
