How-To: Enable Borderless Windowed mode

Hey there all, managed to figure out a simple way to enable Borderless Windowed mode for Fantasy Strike without using any 3rd party utilities.

  1. Right click the game in your library in Steam, click Properties
  2. Click the Set Launch Options button
  3. Enter -popupwindow into the box that pops up
  4. Launch the game, turn off full screen mode if it’s still on.


My game isn’t filling the whole screen! Enable full screen mode, then disable it. This should set the window position so that it does.

The game has black bars at the top/bottom or left/right sides! Adjust your resolution down, then back up to your display’s native resolution.

Hopefully this is helpful to someone, let me know if you have any issues or questions. I’m pretty active in the Fantasy Strike discord as well.
