Change Resolution // Switch FullScreen & Windowed

[SickB]

I have an Ultra Wide with 2560x1080. The game starts in fullscreen, but the picture doesnt fit. i see the menu with the languages. i see start, load and how to play and the next button (i think its quit) is outside of the bottom of the screen. ALT+ENTER doesnt solve the problem. The game goes in Windowed Mode, but i still can´t see everything
