Grand Theft Auto IV is a singleplayer third-person open world and action game in the Grand Theft Auto series.

The PC version allows to import music files for playback in a custom radio station. Rockstar Games has removed some music tracks from the game due to expired licenses. Same with Grand Theft Auto: Episodes from Liberty City. See Restore removed music

Emissive shaders are known to be broken in the PC release, when compared to both Playstation 3 and Xbox 360. See FusionFix for partial fixes. The game has an extensive modding community. See Downgrading. It is also notorious for poor performance (especially on maxed out settings) and frame-pacing issues, even on high-end systems. Lowering settings and/or DXVK are strongly advised.

Essential improvements

Patches

The latest Steam/Rockstar Games Launcher version may be incompatible with some modifications, so downgrading to 1.0.8.0 may be required (check your desired mods' requirements).

Patch 1.0.7.0 and 1.0.8.0 restores multiplayer which is still available to play.

Patches after Patch 1.0.8.0 were released only for the game's digital versions. Although the first numbered upgrade was referred as "1.20", subsequent versions of the game adopted a "1.2.x.x" model.

DXVK

Can vastly improve the game's performance.

Install DXVK

DXVK#Installation Install DXVK to <path-to-game>\GTAIV. Create a text file, name it dxvk.conf, and add d3d9.maxFrameLatency = 1 to it to avoid or reduce occasional frame skipping and stuttering Add d3d9.presentInterval = 1 to the file, which forces using DXVK's Vsync implementation. This may give less CPU overhead compared to the game's own Vsync implementation. Add d3d9.numBackBuffers = 3 to the file. This may further improve frametime stability while using Vsync. Notes: The game may wrongly detect the amount of VRAM available and only show 512 MB instead while using DXVK. The game may need to use over 2 GB of RAM to avoid stuttering while using DXVK.

FusionFix

Fixes various gameplay and visual issues, includes an accurate, adjustable frame rate limiter, and restores and improves broken shaders which were lost or broken as a result of porting from consoles to PC

Includes a mod loader via the folder <path-to-game>\GTAIV\update, which must be used for any internal file modifications in Complete Edition

Only the latest version includes most of the changes, and said version is only compatible with Complete Edition. If you're running an older patch, the only compatible version is 1.10

Installation
Go to Releases and download latest version (or 1.10 if you're running older patches) Extract the contents of the archive to <path-to-game>\GTAIV\ Update Shader Fixes if you want to.

ZolikaPatch

Only compatible with older versions 1.0.4.0, 1.0.7.0, or 1.0.8.0.

Requires Ultimate ASI Loader.

Fixes issues FusionFix does not address.

Installation
Download the ZIP file from bottom of the first post. Extract the files to <path-to-game>\GTAIV\.

Shader Fixes

Restores and improves various visual issues, which were brought during the PC port and updates after 1.0.5.0. The goal is to restore and fix everything from here

Restores and improves effects from the console versions, like depth of field, motion blur, and volumetric lights

Compatible with older patches.

Already included with FusionFix for Complete Edition, but you can update the Main files by dropping them in update folder. Do not add Addons in this case.

Installation
Go to Releases and download latest version Extract the Main folder of the archive to <path-to-game>\GTAIV\ (or <path-to-game>\GTAIV\update folder if you're using FusionFix) Note: If you want Console Gamma on older patches, also extract the folder in Addons

Downgrade Tool

ItsClonkAndre's downgrade tool is a simple-to-use tool to downgrade a digital copy of the game to a retail patch version, such as 1.0.8.0.

Useful for situations where a majority of desired mods and fixes will not work with the Complete Edition.

Also comes with a radio downgrader and additional mods with multiple options.

Skip intro videos

Install FusionFix if you're using Complete Edition or ZolikaPatch if you're using older patches

Edit loadingscreens_pc.dat
Go to <path-to-game>\GTAIV\common\data\. Open loadingscreens_pc.dat with a text editor. Alter the value of "duration" for sections 1, 2, 3, 4, 5 and 6 to "0".

Issues unresolved

Timing-related issues

A framerate higher than 60 FPS can result in timing issues, including, but not limited to:

• Mouse movement is very difficult while using a browser computer.
• In the mission "Out of Commission", while trying to climb onto the helicopter, no matter how often you press repeatedly the jump key, you will not be able to get onto the helicopter.
• Brucie's garage door in the mission "Easy as Can Be" closes, prematurely leaving Niko trapped.
• The use of the virtual keyboard of the police car computer becomes impossible to control with the keyboard due to the sensitivity being increased too much.
• While playing pool, the balls physics breaks, balls don't go as far and as fast as they do.
• Handbrake camera and regular camera movement become excessively-slow, and cutscenes are zoomed-in to the point where the subjects are cut off.

Install Out of Commmission Helicopter Bug Fix[1], which uses the scripts.img from patch 8.

Use FusionFix
Note: Does not completely fix timing-related issues.

Issues fixed

Game language does not follow the Rockstar Games Launcher/Steam settings

Apply Language Loader
Requires Ultimate ASI Loader. Download and extract Language Loader in <path-to-game>\plugins\. Alter GameLanguageID to wanted language in IVLanguageLoader.ini.

No bullet spread/recoil

Apply Bullet Spread/Recoil Fix script
Notes: Requires an ASI Loader. Not recommended to use in multiplayer. Requires 1.0.8.0 or earlier.

Use FusionFix
Note: Requires 1.0.7.0, 1.0.8.0, or the Complete Edition.

Unable to play in offline mode with the game's Steam version

This solution will enable offline mode with local game saves.

Run the game from the Rockstar Games Launcher

Ensure both Rockstar Games Launcher and Steam are already set for offline mode: Rockstar Games Launcher's how-to. Steam's how-to. Disconnect the system from Ethernet and Wi-Fi. Run the Rockstar Games Launcher using Windows' Start Menu, that uses a shortcut to LauncherPatcher.exe (usually located in "%PROGRAMFILES%\Rockstar Games\Launcher"). Run the game from this launcher by clicking "Play on Steam".

VRAM amount is wrongly detected

The game can wrongly detect the amount of VRAM available, showing only 512 MB instead.

Claimed to be fixed on Patch 8, but may still happen on certain system configurations such as laptops with dual GPU configurations, when using wrappers like DXVK or when Downgrading to a pre-Patch 8 game version.

Use -availablevidmem XXXX.0 command line argument and replace XXXX by the wanted amount of VRAM in MB
Notes Using any value above 3072.0 on latest Complete Edition Version seems to cause texture popping all throughout the map. Therefore, it's not recommended to use 4096.0 even if your video card allows it.

Use ExtendVidMem
Works on the Complete Edition. Download the dinput8.dll file in this page. Extract it to <path-to-game>\GTA IV\. Notes Rename the ASI loader's variant of the dinput8.dll file to dsound.dll to use this fix along with Ultimate ASI Loader.

DRM-related errors

Absent from the Complete Edition, where GFWL and SecuROM were removed from the game.

Install the latest Games for Windows - LIVE in case of old versions on Windows 8 or later.

Fatal error: WTV270

See In-game interface does not open

SecuLauncher: failed to start application. [2000] error

Modifications

• GTA Gaming Archive
• GTA Garage
• GTA Inside
• GTA Land

It is strongly recommended to backup any files these mods may replace.

Should not be used in multiplayer.

Script Hook and CE Hook is a prerequisite for some mods.

OpenIV might be required for some mods. Main website is down at the moment - you can use a mirror to download the mod instead.

Installing mods that replace files on Complete Edition follows a different procedure - update folder must include all non-img files in their respective folder structure, while all the .img files must be separately batched into one (or three if they affect EFLC too) .img files with OpenIV in a separate folder.

Run EFLC as DLCs

Unneeded on the Complete Edition.

For older versions from 1.0.6.0 to 1.0.8.0.

Merges the radio stations and songs from EFLC into the base game.

Removes RamJam FM, Self-Actualization FM and Vice City FM radio stations.
