Hello @Danbowie, we’re terribly sorry that you’re dealing with performance issues on the PS4, we are continuously investigating these while also monitoring the forums to gather as much data and feedback as possible from players.
If you could provide additional details for us to relay to the developers, please share them in this thread, which is specific for performance issues. All information, such as base size, thrall count, and even a couple of screenshots for the area responsible for these will help us immensely, thank you for understanding!
