Command Line Arguments

Here are some of the most useful Command Line arguments that can be passed through the shortcut's target area at the end. it would look something like this:

Command Line Argument	Description
-Game	Launches a UE Project as a game instead of with the editor.
-RenderOffscreen	Renders offscreen (Still seen by Live FX)
-ForceRes -ResX=1920 -ResY=1080	Sets the resolution. (Usually needs to match what you want your inner frustum to be).
-RCWebControlEnable	Required to use Web Remote Control
-RCWebInterfaceEnable	Required to use Web Remote Control
-t.maxfps = 23.976	Sets the max frame rate. Helpful if you do not set a project frame rate or need to limit it further.
/Game/Maps/MyMap	Before the other flags, this can launch a specific Map
-DisableAllScreenMessages (isn't working)
