How to Install iCEnhancer 4.0 in GTA IV – Step-by-Step Setup for Stunning Graphics

If you've ever dreamed of playing GTA IV with ultra-modern visuals—reflections on wet streets, volumetric fog, and photo-real lighting—then iCEnhancer 4.0 is the mod you’ve been waiting for.

But before you dive in, there’s one catch: it only works on specific versions of the game. This guide walks you through the full installation process, whether you're starting fresh or modding an existing copy.


๐Ÿ”ง What You Need to Know Before You Start

iCEnhancer 4.0 only works with:

  • GTA IV Patch 1.0.3.0 or 1.0.4.0

  • Clean or mod-ready installation folders

Most Steam users have Patch 1.0.7.0, so you'll likely need to downgrade before installing the mod.

๐Ÿ“ฅ Step 1: Downgrade GTA IV to Patch 1.0.4.0

To avoid crashing or broken visuals, downgrade your game using the official 1.0.4.0 patch or a trusted community downgrade tool. Here’s how:

  1. Backup your game folder first.

  2. Download the GTA IV Patch 1.0.4.0 from Rockstar’s archive or trusted community sources.

  3. Run the patch installer and follow the instructions.

  4. Confirm the downgrade by launching GTAIV.exe — it should display version 1.0.4.0 in the main menu or EXE properties.

⚠️ If you're using Steam, avoid launching the game through the client once downgraded—use the .exe directly.


๐Ÿ“ฆ Step 2: Download iCEnhancer 4.0

Head over to the official mod page:
๐Ÿ”— https://icelaglace.com/mods/ice4.html

  • Download the latest iCEnhancer 4.0 zip file.

  • Extract the contents using 7-Zip or WinRAR.

  • Open your GTA IV install folder (same one as GTAIV.exe).

  • Drag and drop all mod files into the folder. Overwrite if prompted.


⚙️ Step 3: Configure ENB & Shader Settings (Optional but Recommended)

Inside the mod files, you’ll find:

  • enbseries.ini

  • iceconfig.ini

  • iceShader.fx

Here’s what you can tweak:

  • Disable Depth of Field (DoF): Great for performance.

  • Adjust reflections or bloom: Useful if roads look too shiny.

  • DXVK integration: Advanced users can add Vulkan support for better FPS on modern GPUs.


๐ŸŒ† Step 4: Add Compatible Mods (Optional)

For the ultimate GTA IV overhaul, consider adding:

  • HD Roads Pack

  • Euphoria Physics Enhancer

  • Real Vehicle Pack

  • Better Trees & Vegetation

Be sure these mods are also compatible with Patch 1.0.4.0. Use OpenIV or IMG Tool to import .img files correctly.


๐Ÿš€ Step 5: Launch the Game

  • Use GTAIV.exe from your folder.

  • Avoid launching from Steam to prevent updates or version conflicts.

  • If you see stunning visuals, enhanced shadows, glowing reflections, and dynamic weather—you’re good to go!
