Possible to change video settings (resolution, etc.) from FAF or do I have to go to vanilla game?

Title says it all, sorry if it's a dumb question or has been answered already somewhere.

@muaddale it not possible from faf. But you can do it in the game.prefs accessible by the burger menue of the FAF client. The section regarding resolution is nearly all the way at the bottom. Windowed mode is an option as well. there is also the possibility to hide the taskbar etc:

Awesome! Thanks so much!
