I can only guess its a resolution issue more than a hardware issue.
I literally can run the game in Borderless Windowed on Ultra everything, in ever aspect of the game 'except' Fleet Battles and never crash. Fleet battles require i turn that setting down to medium, "if" i want to run the game across all 3 screens via Nvidia Surround, or i'll crash on loading to the point were i'd be 'in' the fighter.
If i run the game in a window, i never crash, at any video option from low, to ultra. (though when its in a window, i keep the window inside 1 single monitor, keeping it at roughly 1080p resolution)
That 1 single, specific, option seems to be the culprit. and its specific to the Fleet Battle maps.
I can only guess that something with their files that setting runs off of, were not made with our larger resolutions in mind, and the game 'breaks' when it tries to load them stretched out that big. (yet it has no problems with any of the other Graphical things being super-sized 😃 nore with it being set to even Ultra in 'other' game-modes.)
