[2019] Ps4 Pro Problems?

My Girlfriend and I picked up the game when it became free for ps+ subscribers - first I thought the game itself is horribly bugged, but it seems its only on my playstation pro, while her playstation slim seems to play the game a lot smoother and better. We tried to switch playstations to make sure its not a problem with the account or playstyle. Also, both playstations are stationed next to each other, so internet connection shoudn't be the problem. Also, playing other online games (vermintide, warframe, destiny 2, fallout 76) is fluid. Already tried to reinstall the game.

Problems I encounter on ps pro that she doesn't on ps slim:

- Buildings disappearing / only beeing half there. Takes up to several minutes to load them.

- Hacking on a stone/tree will be registered with an extreme delay and then will make the stone / tree disappear with one hit. It will reappear about 30-60 sec later, then I can harvest it normally.

- Enemies sometimes won't spawn in for me for 20-40 seconds, a time during wich she can already attack them. Sometimes I get damaged out of nowhere, guess its an "invisible enemy"

- Sometimes Enemys bug out and run straight forwards very fast. This only happens if I'm the one who aggros the enemy, tho she can see the enemy just running past us in this cases.

- Sometimes my Stamina / health won't deplete and hits won't register on enemys, just what you'd expect when a huge serverlag ocures - just that it only lags for me and not for my gf

Problems she encounters on the playstation slim that don't occure on ps pro:

- Game shut down thrice by now.
