I'm not well versed on ultrawides, but I do want to give you a word of caution.
From what I've seen, ultrawide isn't really supported that well by this game.
Users needing to use specific launch commands to make it fit the screen (But not always being allowed to do this)
I'm not 100% sure if this is a super common issue and if it can be resolved, but I've seen it come by a decent amount of times, so I'd recommend looking into that, checking out what the limitations are, before you do decide to move over.
