Playing with the new FOV slider in beta patch 4…
For me, a FOV of 85 looks really nice used with the ini tweak described above (changing or adding the MaintainYFOV parameter).
It looks just as good as the default FOVof 95 at 16:9, with one exception which is the menus/HUD: They still get chopped off at the top and bottom.
This is becuase the ini tweak only ensures the Y aspect fits your monitor setup.
Devs, if you can get the game top fit both the X and Y aspects at custom resolutions, it should fix the menu/HUD issue.
As it is its quite playable, but still slightly annoying having the HUD cut off.
Also I’d recommend having that ini tweak changed by default in the meantime as it is a huge improvement and doesn’t affect the game at standard resolutions.
