The problem mostly occurs in port but and more rarely in battles, with the game freezing up and giving a black screen which forces me to close the application trough task manager.
Increasing the other settings has no impact, only the water quality, and if all other settings are maxed out except for that one, the game runs perfectly fine. I already ran the launcher repair utility, WGCheck, checked drivers, Windows updates, GPU temps and everything is up to date and working as intended. The problem also occurs in safe mode without mods.
My PC configuration includes: GPU: RX 580; CPU: Ryzen 1600; RAM: Corsair Vengeance DDR4 16GB 3200Mhz
