commandline.txt for GTA 4 doesn't work on Steam

I have GTA 4 on Steam and I use commandline.txt but it doesn’t work. When I launch it, Rockstar Social Club just pops up asking me to log in and after I click Play or Play Offline, the game starts and commandline.txt doesn’t work just as if it’s ignored

I’ve tried:

  • What happens when I block someone on Steam?
  • Can I give away Steam games?
  • How do I get an older Windows 95/98 game to run in Windows 7 64-bit without some colors looking off?
  • Why are Steam's “hours played” numbers wrong for so many games?
  • How do I remove a Steam game from my library?
  • Can I trade a Steam game that I don't want?
    • Running without Steam (Desktop shortcut to LaunchGTAIV.exe)
    • Arranging the options so that they’re all on one line
    • Arranging the options so that each option is on one line
    • It’s updated ( ’cause Steam updates it

    Also, I didn’t make any spelling mistakes ’cause none of the options worked

    My commandline.txt

    Steam launch options doesn’t seem to work either

    Never mind. Steam launch options are working again.

  • How many friend slots do you start off with, and how many do you get per Steam level?
  • Can the Steam achievements be gained also offline?
  • Are there alternate methods to activate Steam CD Keys?
  • How can I sync achievements for Steam games bought through another vendor?
  • Can you run games with non-trivial graphics requirements in a virtual machine?
  • Enable “Play” button for Undertale on Linux Steam

    Steam has built-in support for letting you specify command-line args for games.

    Right-click the game’s entry in the Library and click Properties. On the window that pops up, there’s a button named “Set Launch Options…”, and clicking that gives you a textbox that lets you type in command-line arguments that Steam will use when launching your game.

    You can include the entries you would’ve had in commandline.txt in there (all on one line, of course, since the textbox in Steam is one line only).
