Game spreads basically perfect. Hor+ & FOV proper. Guns, aim, vehicle-views & HUD are all proper. HUD element-positions span full width, but are fairly adjustable (via Safe Area in Options). Rendered cutscenes full hor+, FMVs usually pillarboxed (rarely full vert-). All text & menus are proper (menu text on center, with rendered background either pillarboxed or hor+). Bloody injury overlay stretched full (looks fine).
