UI scaled too far

Hello friends,

I tried the settings ui-scale to 150%, but now my screen is zoomed in so much that I can't even start a game.
How do I revert this?
Are there settings stored somewhere in a file that I can edit? Doing it via the context menu is impossible, as I cannot open it from in-game. Please help, I want to play ...

search for your Game.prefs file:
C:\Users\Uveso\AppData\Local\Gas Powered Games\Supreme Commander Forged Alliance\Game.prefs

Open it and search for:

ui_scale = xyz,

and change it to:

ui_scale = 1,

save the file, start the game.
