Force Fullscreen FOnlineD3D.exe launch options?

[IXxTNTxXI]

Hello fodev Community,

i have the following question:
Is it possible to force start FOnlineD3D.exe in real fullscreen?
i allready checked "Fullscreen" in FOConfig.exe but the game starts in "fake" fullscreen.
it is an 1920x1080 borderless Window-Mode but not real fullscreen.

maybe there are some hidden launch options like "-fullscreen" for the shortcut?

Thanks
TNT
