Launch options make sure that specific commands are loaded each time you start the game. CS2 has changed and removed several commands, meaning that you can no longer modify your gameplay in the same way as in CS:GO. However, in most cases, it won’t be necessary to change any settings in the launch options.
Here’s how you find the launch options:
From Steam Library, right click on Counter-Strike 2 and choose Properties.
Under the General tab you’ll find Launch Options at the bottom of the page.
