This page may require cleanup to meet basic quality standards. The specific problem is: (Mrntptrs:) Unclear which fixes and mods work on the latest Complete Edition version (1.2.0.59) and which requires downgrading. Maybe too many mods are listed; should maybe only list the best mods). You can help by modifying the article. The discussion page may contain useful suggestions.

Warnings

For Games for Windows - LIVE on Windows 8 or later, install the latest Games for Windows - LIVE software.

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.[1][2] 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[3]. Lowering settings and/or DXVK are strongly advised.

Issues fixed

Timing-related issues

An unlocked or incorrect frame rate cap (+60FPS) can result in timing issues.

Related issues

  • 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
  • In the mission "A Revenger's Tragedy", while chasing the helicopter on your boat, the Jacob's helicopter crashes and you are not be able to achieve.
  • The weapons of the enemies are floating in the air (+200fps)
  • While playing pool, the balls physics breaks, balls don't go as far and as fast as they do.
  • The elevating work platform rises faster than normal
  • Too slow handbrake camera and regular camera movement and too zoomed-in cutscenes
Cap frame rate to 60 FPS[20]
Enable Vsync in the options game and set refresh rate on 60hz
Install Out of Commmission Helicopter Bug Fix[1], which uses the scripts.img from patch 8.
For Regular camera movement and handbrake camera are too slow and Cutscenes are too zoomed in Use FusionFix (keyboard and mouse controls only)[21][22]

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

Apply Language Loader[23]
Requires Ultimate ASI Loader.
  1. Download and extract Language Loader in <path-to-game>\plugins\.
  2. Alter GameLanguageID to wanted language in IVLanguageLoader.ini.

No bullet spread/recoil

Bullet spread/recoil is enabled only when playing with a controller by default, resulting in 100% shooting accuracy when using a keyboard and a mouse.[citation needed]
Apply FusionFix[24]
Works on the Complete Edition.
Apply Bullet Spread/Recoil Fix script[25]
Requires an ASI Loader.
Not recommended to use in Multiplayer.
Never got updated for the Complete Edition, likely incompatible.

Stuttering, texture popping and other performance issues after running the game for a while

Forcing available memory on Version 1.0.8.0 is not recommended; it will make the game unstable.[citation needed]
Force maximum available memory[26]
  1. Create a file named commandline.txt in the game's root folder.
  2. Enter one of the following codes in to the newly created file depending on the texture quality set:
    • Low textures (256 MB VRAM): -memrestrict 230686720
    • Medium textures (512 MB VRAM): -memrestrict 314572800
    • High textures (1 GB+ VRAM): -memrestrict 681574400
  3. Save the file and run the game.

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[27]
  1. Ensure both Rockstar Games Launcher and Steam are already set for offline mode: Rockstar Games Launcher's how-to. Steam's how-to.
  2. Disconnect the system from Ethernet and Wi-Fi.
  3. Run the Rockstar Games Launcher using Windows' Start Menu, that uses a shortcut to LauncherPatcher.exe (usually located in "%PROGRAMFILES%\Rockstar Games\Launcher").
  4. 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,[28] but may still happen on certain system configurations[29] such as laptops with dual GPU configurations[30], 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[31]

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.[32]
Use ExtendVidMem[33]
Works on the Complete Edition.
  1. Download the dinput8.dll file in this page.
  2. 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.

FLAC is not supported. Convert them to WMA Lossless to use them in-game.
Monaural audio files are not supported.

Downgrading

Some mods may not work on the game's latest version (1.2.0.59). Consequently, the most recommended versions for modding are 1.0.4.0 up to 1.0.7.0,
Steam guide for downgrading the Complete Edition to versions 1.0.4.0, 1.0.7.0, or 1.0.8.

Notes

Delete any plugins, like FusionFix, from the game folder before using this method.
Can keep DLCs in one game, Steam achievements and the 3 EFLC-exclusive radio stations.
Works with GFWL (delete xlive.dll from the game folder and XlivelessAddon.asi from the plugins folder and get the GFWL code protection disabler to enable GFWL) and multiplayer clients.
Has a beginner-friendly installer with a guide.
It is alternatively possible to play Singleplayer without any requirements for GFWL thanks to xlive.dll.
Downgrading to Version 1.0.4.0 removes DLC support.
Install Patch 4 (1.0.4.0)[citation needed]
  1. Extract and run the installer.
  2. Download the font fixes.
  3. Place fonts.dat and fonts_r.dat into <path-to-game>\common\data\.
  4. Download and install XLiveLess.

Notes

An older Script Hook version is needed for modding on Version 1.0.4.0, found here.
Some mods only work on Version 1.0.4.0, while other mods, like ColAccel, do not work on that version at all.
This version is claimed to have better game performance.[36][37]
Install Patch 7 (1.0.7.0)
  1. Extract the files.
  2. Run UpdateTitle.exe and install it.
  3. Download and install XLiveLess.

Notes

Only works when downgrading from Version 1.0.8.0 to 1.0.7.0.
Version 1.0.7.0 has better graphics, DLC support, many bug fixes, secondary key-bindings and more.
Many report a performance decrease on this version compared to Version 1.0.5.0 or older due to a better shadow quality starting with Patch 6.

Reduce loading times

Place ColAccel script in <path-to-game>[38]
Requires an ASI Loader.
Supports the Complete Edition.
Greatly reduces loading times.
May cause bugs and/or other inconsistencies, mostly related to scripted models or objects that alter their appearance via story progression.[39]

Restore removed music

Over 50 radio station tracks were removed from the game in April 2018 due to expired licenses.[40]
Downgrading the Radio Stations[41]
  1. Download the (music) downgrader.
  2. Unpack to the installation folder.
  3. Run install.bat.

Ultimate ASI Loader

Ultimate ASI Loader is a tool that loads custom libraries with the ASI file extension.
Needed by FusionFix and ZolikaPatch.
Installation[42]
  1. Download the Ultimate-ASI-Loader.zip file.
  2. Extract the file to <path-to-game>\GTAIV\.

Use over 2 GB of RAM

The game will only use up to 2 GB of RAM by default; this can be adjusted to up to 4 GB. Extending this limit may be needed while using wrappers, like DXVK.
Edit stream.ini[43]
  1. Go to <path-to-game>\GTA IV\pc\ and open the stream.ini file.
  2. Alter every occurrence of 204800 to 409600 and save the file.

XLiveLessAddon

Disables Games for Windows - LIVE.
Includes Ultimate ASI Loader.
The location of the savegames alters to %USERPROFILE%\Documents\Rockstar Games\GTA IV\savegames\.
Adds borderless windowed mode.
Allows running the game directly from GTAIV.exe.
Gives an option to skip intro videos and the main menu.
Disables LIVE multiplayer acess. LAN multiplayer is still accessible, but connecting to a LAN lobby crashes the game.[citation needed]
Installation[44]
  1. Download the XLivelessAddon.zip file.
  2. Extract the contents of the download to <path-to-game> (replace the file when prompted).

DXVK

DXVK is a Vulkan-based translation layer for Direct3D 9-11 games.
May vastly improve the game's performance due to its added shader/state cache systems, advanced multithreading support and extended draw call handling capabilities.
May prevent some ENB shaders, like ambient occlusion, from caching and rendering.[45]
Install DXVK[46]

Notes

Create a text file, add d3d9.maxFrameLatency = 1 to it and save it as dxvk.conf in <path-to-game>\GTAIV\ to avoid or reduce occasional frame skipping and stuttering; this command ensures only a single frame is buffered by the CPU ahead of time.[47]
Adding d3d9.presentInterval = 1 to the dxvk.conf file enables Vsync; using Vsync via DXVK may give less CPU overhead compared to the game's own Vsync implementation.
Adding d3d9.numBackBuffers = 3 to the dxvk.conf file may further improve frametime stability while using Vsync; this command ensures Triple Buffering is active.
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.

Modifications

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.

FusionFix

Aims to fix some issues on the Complete Edition (version 1.2.0.30 or later), including emissive shaders which don't behave as they do on consoles.[1][2]
Installation[48]
  1. Download the GTAIV.EFLC.FusionFix.zip file.
  2. Extract the files to <path-to-game>\GTAIV\ (replace the files when prompted).

Notes

See this for Version 1.0.8.0. It is recommended to use ZolikaPatch otherwise.

ZolikaPatch

Only compatible with older versions 1.0.4.0, 1.0.7.0, or 1.0.8.0.
Requires Ultimate ASI Loader.
Started as a bug fixing mod and added some graphical overhauls.
Fixes issues that FusionFix does not address.
Requires downgrading to an older version of the game..[49]
Installation[50]
  1. Download the ZIP file from bottom of the first post.
  2. Extract the files to <path-to-game>\GTAIV\.

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.

IV HUD & Radar overhaul

Aims to accurately remake every texture of the HUD in higher resolution.

Beta Whiz Phone

Makes the phone model better match the Whiz Phone's cutscene model.

CG4 Radar/Map

Adds more details and information on the world map and improves its look.

Clean IV

Improves the game's saturation and removes the gray-green filter.

DayL's Natural Timecyc

Makes the game less dark/grey, more natural and more vibrant.
No Performance drop so perfect for low end hardware.
Compatible with every patch/version of GTA IV.

Draw Distance Tweak

Allows larger draw distances.
Not compatible with most visual mods because it replaces timecycle files.

EFLC PC Quality Texture & GTA IV&EFLC Graphics Fix

For versions 1.0.7.0 and 1.0.8.0.
Should be installed before FusionFix.
Fixes some minor graphical issues and replaces the low quality textures in EFLC by better quality ones.

ENBSeries graphic modifications

Popular modification amongst YouTuber and other content creators.
ENB Series graphical enhancement was never meant to work on Version 1.0.5.0 or later[51], and the particular ENB version must support Version 1.0.8.0 (so also dax.dll fix included) (IV | EFLC), otherwise the game may display a black screen. This instruction is additionally needed to fix the Social Club error on the Rockstar Games Launcher / Steam version.
One of the very few working ENB modifications with the Rockstar Games Launcher version (and also 1.0.8.0) is Excellent ENB and its versions from at least v3 (with Social Club error fix above) and later.
