Re: Not allowing change of resolution.
@Locolind64 Instead of of writing -window try -fullscreen if that wont help try to manually change resolution and to full screen within config file thats located in C:\Users\Your User Name\Saved Games\Respawn\Apex\local. Files name is videoconfig change these lines:
"setting.defaultres" "here put your desired width"
"setting.defaultresheight" "and height"
"setting.fullscreen" "1"
