I’ve released a new version of my launcher that includes one feature that I’ve personally been wanting in it for a while.

Proper Command-line Argument support.

Below are the command-line arguments you can use for Wow.exe [source]:

-console

Allow access to console in game.

-d3d

Run the game using Direct3D (default under Windows).

-fullscreen

Run the game in full screen.

-nosound

Run the game without sound.

-opengl

Run the game using OpenGL (default under Mac).

-swtnl

Run the game using Software T&L.

-windowed

Run the game in windowed mode.

-maximized

When used with -windowed, runs the game window maximized.

–widthxheight

Sets the resolution to width by height. note: it is not known if this works with abnormal resolutions. it is recommended to only use resolutions known to work with WoW.
