I didn't think of this until right now, but after the first comment they made, they tried to say that it's the PS4 that was the cause of lower framerate anyways due to its CPU. So many NPCs in the game with so it was the AI architecture that was slowing it down. There are a lot of people in the game, but most of them are standing in the same spot, and the other ones in the game are walking from point to point.
So what just popped into my head?
The game is going to be garbage, guaranteed, and it's in its alpha stage, but the game looks to run a minimum of 30fps. Just look at the video below to see how many enemies are on screen at once. The AI is stupid, but that doesn't change the fact that they actually AI programmed into each enemy rather than for nothing more but the AI to react when brushed up against.
