In very high populated areas, there are so many people on screen that a bunch end up disappearing until I move to another area of the screen; after moving people will reappear based on their location on my screen.

Is there a way to prevent anyone/anything from disappearing? Like some sort of graphics setting that can prevent it? During the Odin/Behemoth fights, having people/enemies disappear makes it impossible to do anything efficiently. I know someone suggested targeting someone that is targeting the enemy, and pick their target, but that doesn't work when the enemy doesn't show up on my screen.

Any help with this would be appreciated.
