Extreme lag FPS issues after beating game PS4

I have the dlc handsome collection for ps4, I never had issues with lag before on TPS up until I got to the Vault. At the time it wasn’t that bad, could still play. But after I beat the game, it has become unbearable. The fps is so bad I can’t even walk/shoot without at least a second delay or even load scenery. Even when I start a new character, its the same thing.

I’ve owned this game since it came out with no problems until now, no new updates recently the only difference was beating the vault level.

I realize there were problems at launch with the ps4, but I was under the assumption it was fixed by now.

Please help!!!

I have not heard anything about this yet I guess all you can do is cross your fingers for a patch
