Hello everyone, in this simple and quick guide I will give you the commands available for you to change the game resolution or go full screen/window/borderless.

By default the game starts at a windowed resolution, but you can change it by:

1. Right-click the game in your library.
2. Go to Properties
3. Go to Set Launch Options...
4. Input the following depending on what you want:
a. "-screen-height X" - The game screen will start with the X height you entered.
b. "-screen-width X" - The game screen will start with the X width you entered.
c. "-screen-fullscreen X" - X can be 0 or 1. 0 starts the game in windowed mode while 1 starts the game in fullscreen mode.
d. "-popupwindow" - The game will start in borderless window mode. If you are using multiple monitors you can quickly change where the game is displayed with Win+Shift+Left/Right.
