iCEnhancer 4.0 is not lightweight. Expect a 30–50% FPS drop compared to vanilla GTA IV.

iCEnhancer 4.0 remains a landmark achievement in GTA IV modding, transforming Liberty City into a believable, atmospheric world. However, it is not a plug-and-play mod. Successful installation requires careful version matching, downgrading, and manual tweaking. For users unwilling to troubleshoot, lighter visual mods are recommended. For those who persevere, iCEnhancer 4.0 can make GTA IV look—at times—indistinguishable from a modern release.

Final Advice: Always scan downloaded .dll and .exe files via VirusTotal, and avoid any download that asks for a “password” or “survey completion.” Join the GTA IV Modding Discord community for verified file links and real-time help.

iCEnhancer 4.0 was officially released in July 2025 by creator Hayssam Keilany, marking the first version of the mod to feature physically-based lighting. It is widely considered the most stable and performant version of the series, significantly updating the game's original "dark and dull" aesthetic with ultra-realistic visuals, improved water, and better fog rendering. Essential Pre-Installation Requirements

Game Version: For maximum compatibility and visual quality, you must downgrade your game to patch 1.0.4.0 (or 1.0.3.0). Modding the standard Steam/Epic Games "Complete Edition" directly often results in buggy reflections and broken lighting.

Clean Install: It is highly recommended to start with a fresh installation and create a backup of your save files and game folder before proceeding. Step-by-Step Installation Guide

Downgrade the Game: Use a tool like Grand Theft Auto IV Patch v1.0.4.0 to roll back your game version.

Install ENBSeries: Download the core ENB files. Open the ZIP and copy everything from the "Wrapper version" folder into your main GTA IV directory. Install iCEnhancer 4.0:

Download the mod from the official source at icelaglace.com.

Extract the files and copy all contents into the root directory of your game, overwriting files when prompted.

Configuration: Once in-game, you can customize effects by pressing Shift + Enter to open the ENB menu. Troubleshooting & Optimization

Always scan downloaded .rar or .zip files with VirusTotal before extracting. Legitimate iCEnhancer 4.0 should never contain .exe launchers—only .dll, .ini, .fx, and texture files.
