Not allowing change of resolution.
Resolution will not allow to change out of 1280x720. I am able to run the game at max settings and it runs perfectly fine but it will not allow me to change any resolution settings as well as change from windowed to full screen. Resetting the video settings to default does but it in full screen but still at 1280x720.
@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"
