Overview#

Welcome to Gillian's Grand Theft Auto IV Modding Guide, a centralized and modular all-in-one modding guide.

This guide aims to provide the best vanilla-faithful experience for GTA IV, but is not limited to that. It's meant to be accessible to everyone and to be able to help anyone who has their own specifics on how they want to experience the game - be it creating the best singleplayer experience, creating the best environment for manual modding, playing multiplayer, getting the best performance, or something else.

This guide aims to be as unbiased as possible, and tries to provide only relevant information for modding GTA IV. Any mods or information listed do not reflect my personal opinion of anyone, and I'd prefer this guide to be free of personal bias.

However, one strict rule is enforced: all modifications mentioned must preserve the original feel of the game.

Prerequisites#

In order for this guide to be useful to you, and for you to be eligible for support later, please make sure the following prerequisites are met, aswell as my additional requirements:

  • Read everything as is and don't skip anything.
  • Avoid using other guides unless they are mentioned in this one. If something is mentioned in other guides but not here, it is most likely not useful here.
  • I do not provide support for ENBs and other graphical enhancements (i.e. ICEnhancer). You're on your own for those.
  • You must own the game on Steam or the Rockstar Games Launcher. Pirated versions will not receive guaranteed support from me if any problems occur. Other versions may work, but no guarantee is given, nor will I provide support if any problems occur.
  • Operating system: Your PC should be running Windows 10 or 11 or any up-to-date Linux distribution suited for gaming. Older Windows versions may work, but I will not provide support for them. ARM64 systems have not been tested.

  • Hardware: Your PC must meet the minimum requirements of the game. For the best experience, it should also meet my personal recommended spec sheet below which ensures pleasant gameplay with mods at Full HD resolution and 60Hz screen. Scale manually for your own needs:

    Hardware Recommended Alternative
    CPU Intel Core i5-6600k Ryzen 3 2200G
    GPU GTX 980/1060 RX580, Intel Arc A310
    RAM 8 GB
    Storage 30 GB (Ideally SSD) If manually modding, ~70 GB for backups

  • Go to preparation to get ready to mod the game and start using the guide:
