So you’ve installed iCEnhancer 4.0, rebooted GTA IV, and now Liberty City looks like a cinematic masterpiece. But guess what? You’re only halfway to perfection.
To truly unlock GTA IV’s full potential in 2025, you need more than just beautiful lighting. You need performance fixes, enhanced textures, smarter camera systems—and a few quality-of-life mods to tie it all together.
Here are 5 essential mods that work beautifully with iCEnhancer 4.0, transforming Rockstar’s gritty classic into a stunning, modern open-world experience.
๐ ️ 1. Fusion Fix + ZolikaPatch – Stability First
Before you add any bells and whistles, you need a stable foundation—and that’s where Fusion Fix and ZolikaPatch come in.
Why you need them:
-
Fixes bugs from the GTA IV PC port (broken shaders, mouse input issues)
-
Resolves compatibility problems with ENB and iCEnhancer
-
Improves cutscene playback and framerate pacing
⚠️ Pro tip: Apply this fix right after downgrading to Patch 1.0.4.0. It’s lightweight and absolutely essential for a smooth experience.
๐ 2. Project2DFX – Bring the Skyline to Life
Ever notice how Liberty City feels… flat, even with better lighting? Project2DFX fixes that.What it does:
-
Extends the draw distance of coronas and LOD lights
-
Adds real-time light sources to skyscrapers, bridges, and cars
-
Makes nighttime look alive when paired with iCEnhancer’s volumetric fog
This mod makes Liberty City’s skyline glow like a true modern metropolis—especially when you’re driving across Broker Bridge at sunset.
๐ผ️ 3. 4K2K Road & Building Textures – Next-Gen Feel
iCEnhancer boosts the lighting engine, but textures still matter. High-resolution texture packs fill in the detail.
Recommended options:
-
4K2K Road Pack – adds ultra-detailed asphalt, sidewalks, manholes, and road signs
-
HD Building Retexture – improves glass reflections, wall details, windows, and interiors
Combined with iCEnhancer’s shadows and reflections, these textures deliver a truly photorealistic Liberty City. Just be sure you’ve got enough VRAM (8GB+ recommended).
๐ฎ 4. Ultimate ASI Loader – Unlock Script-Based Mods
Ultimate ASI Loader doesn’t change the visuals—but it’s the gateway to most script-based enhancements.
Why it’s critical:
-
Required for most trainers, first-person camera mods, and advanced reshades
-
Works silently in the background to load
.asiplugins on startup -
Compatible with iCEnhancer and Fusion Fix setups
Once installed, you can stack immersion mods, vehicle tweaks, or custom shaders with confidence.
๐️ 5. First Person Mod or Zolika Trainer – Pure Immersion
Want to feel inside Liberty City? Add a first-person camera mod or use the Zolika Trainer to enable immersive features.
What they offer:
-
Play GTA IV from Niko’s perspective in first-person
-
Change weather, time, traffic, and pedestrian behavior
-
Spawn vehicles or manipulate physics on the fly
It’s perfect for roleplay, cinematic screenshots, or just exploring the city with iCEnhancer’s lighting engine in full view.
⚙️ Bonus: Realism IV & Minor Enhancers
Want to go even further? Try these optional mods:
-
Realism IV: Overhauls physics, recoil, vehicle handling, and AI behavior
-
HD Blood & Fire FX: Replaces particle effects with sharper versions
-

These don’t interfere with iCEnhancer but help complete the experience.
