Why Fusion Fix matters

• Fixes notorious PC bugs: z‑fighting, broken post‑processing (Definition/DoF/Motion Blur/Bloom), washed‑out colors, missing volumetrics/soft particles, and cutscene judder above 30 FPS.

• Modern performance & stability: faster loads, optional DXVK/Vulkan toggle (stutter‑free rendering on many systems), launcher skip, and small physics fixes (e.g., the helicopter bug).

• Quality‑of‑life: granular graphics sliders (DoF/Motion Blur/Bloom strength), centered camera options, immediate aiming from cover, improved sniper controls, Always Run, adjustable camera recenter delay, and optional camera shake scaling.

• Attention to detail: restored vehicle light colors from TBoGT, turn indicators and hazards, seasonal events (winter snow, Halloween atmosphere) you can trigger on demand.

Bottom line: With Fusion Fix, the PC version finally looks and feels like the best way to play GTA IV in 2025.

Visual fixes

• Z‑Fighting Eliminated: Depth precision reworked to match the Xbox 360 approach.

• Definition Untangled: Removes leftover AA logic; provides a sharper, cleaner image.

• Depth of Field (DoF): Properly scales up to 4K, with its own toggle/strength.

• Motion Blur: Consistent intensity at any frame rate, with an on/off slider.

• Bloom: Resolution‑correct scaling and a modernized look.

• Volumetric Lights & Soft Particles: Restored and smoothed; no more particle clipping.

• Console‑accurate Color: Console Gamma brings back the punchy 360 curve.

• Tone Mapping: Optional highlight handling for a less harsh HDR look.

Gameplay & camera

• Cutscenes fixed at >30 FPS: FOV and judder issues solved.

• Centered camera options: On‑foot and/or in‑vehicle; plus cover‑corner aiming is instant.

• Sniper improvements: Move while scoped; aim without scope if you want.

• Always Run: Jog by default; walk with a key when needed.

• Controller feel: Adjustable camera recenter delay specifically for controllers.

• Camera shake: Frame‑rate independent with the ability to disable it.

Polishing touches

• Vehicle lights restored: Correct red/amber/headlight colors for TBoGT vehicles.

• Indicators & hazards: Auto‑blink on turns; hazards after windshield ejection.

• Seasonal events: Optional snow/Halloween vibes via menu or phone numbers.

Installation (safe & simple)

Supported game: GTA IV: The Complete Edition (latest Steam/Rockstar Launcher build). Older patches can work but aren’t officially supported—use at your own risk.

• Back up: Copy your clean Grand Theft Auto IV folder somewhere safe.

• Download Fusion Fix: Grab the latest release from the official page.

• Extract to game folder: Unzip directly into the main GTA IV directory (where GTAIV.exe lives). A plugins folder and config file will be added.

• First run: Launch the game once to generate configs. If you prefer, enable Skip Intro/Menu in Game settings for faster loading.

• Configure options: In the in‑game Graphics and Game menus (or FusionFix.ini), tune:

Console Gamma (colors), Bloom, DoF, Motion Blur (strengths/toggles)

• DXVK toggle (on systems that benefit from Vulkan)

• Camera: center on‑foot/in‑car, recenter delay, shake

• Always Run, Seasonal Events

• Verify stability: If you use other mods, add them one by one and test.

Quick troubleshooting

• Stutter on some systems: Try enabling DXVK (Vulkan). If you already use global DXVK, prefer the built‑in toggle and remove external DLLs to avoid conflicts.

• Controller micro‑stutter: Reset Fusion Fix settings, then re‑apply changes gradually. Reduce overly aggressive post‑FX while testing.

• Crashes after copying old configs: Delete FusionFix.ini to regenerate defaults.

• Night vehicle shadows glitchy? Keep the Vehicle Night Shadows option off if you observe artifacts.

Frequently asked

Is Fusion Fix safe to use online? It modifies the single‑player game’s behavior and visuals. Avoid mixing with online/Live features. Play single‑player.

Does it work with older (pre‑CE) patches? Official support targets the Complete Edition. Some users run it on 1.0.8.0 with extra steps, but it’s DIY territory.

Can I use it with ENB/NVR‑style graphics mods? Yes, but add one mod at a time. Fusion Fix already corrects much of IV’s pipeline; stack carefully and test performance.

Will it fix every crash? No mod can fix everything, but Fusion Fix addresses the biggest PC issues and adds tools that make diagnosing conflicts easier.

Pro tips for the perfect replay

• Cap cutscenes at 60 FPS if you stack heavy reshade/ENB to keep pacing consistent.

• Prefer borderless‑window + VRR/G‑Sync + DXVK for ultra‑smooth traversal.

• Keep your save files backed up separately before experimenting with bigger mod lists.
