In case it helps, I need to configure the controls as XInput to get the game to start. It won't start with DirectInput.
And to see the game in full screen, I simply hide the taskbar with an AHK script:
Run, RSLauncher.exe
sleep 4000
WinHide, ahk_class Shell_TrayWnd
WinHide, ahk_class Start
sleep 1000
Esc::
WinShow, ahk_class Shell_TrayWnd
WinShow, ahk_class Start
Process, Close, AutoHotkey.exe
Run,taskkill /im "AutoHotkey.exe" /F
Process, Close, RSLauncher.exe
Run,taskkill /im "RSLauncher.exe" /F
Process, Close, SWArcGame-Win64-Shipping.exe
Run,taskkill /im "SWArcGame-Win64-Shipping.exe" /F
ExitApp
return
