===Patches===
{{ii}} For patch releases after Patch 8, you must update through Steam or the Rockstar Games Launcher.
+
{{ii}} Patches after 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.
{{ii}} [https://community.pcgamingwiki.com/files/file/1056-grand-theft-auto-iv-patch-8/ Patch 8] updates the game to version 1.0.8.0
 
{{ii}} [https://community.pcgamingwiki.com/files/file/1055-grand-theft-auto-iv-patch-7/ Patch 7] is also available (may be required for some mods, as much as [[#Downgrading|Patch 4]]).
 
{{++}} Since [https://community.pcgamingwiki.com/files/file/1054-grand-theft-auto-iv-patch-6/ Patch 6] Rockstar Social Club is no longer required to run the game.<ref>https://games.softpedia.com/progChangelog/Grand-Theft-Auto-IV-Patch-Changelog-30489.html</ref>

# Extract the contents of the download.

# Add <code>d3d9.presentInterval = 1</code> to the file, which forces using DXVK's Vsync implementation. This may give less CPU overhead compared to the game's own Vsync implementation.
# Move the {{code|common}}, {{code|pc}} and {{code|plugins}} folders to {{code|{{p|game}}}} (replace the file(s) when prompted).
+
# Add <code>d3d9.numBackBuffers = 3</code> to the file. This may further improve frametime stability while using Vsync.
# If you have [[Grand Theft Auto: Episodes from Liberty City|EFLC]] installed as DLC in the GTA IV folder, also move the {{code|TBoGT}} folder to {{code|{{p|game}}\DLC\}} (replace the file(s) when prompted).

'''Troubleshooting:'''
 
{{Fixbox|description=Troubleshooting|fix=
 
'''Q:''' My game is crashing.
 
 
'''A:''' Delete hints.dat from your GTAIV folder or alternatively re-download the dll and replace your old one.
 
 
'''Q:''' My Antivirus/web browser marks this file as a virus, what do I do?
 
 
'''A:''' It's common for an Antivirus or Web Browser to mark certain system files as a virus and since dinput8.dll is a system file which gets loaded by the game, most antiviruses will detect it since it's not signed, hence why I have provided the source code if you want to read the code and compile this yourself.
 
 
'''Q:''' What does this do?
 
 
'''A:''' I pretty much just hook GetMaxAvailableVideoMemory (not an actual name, I named this myself) which returns the max available video ram in GTA IV and modify it to return something else. I also create a hook to Direct3DCreate9 to get the D3D device the host application creates and figure out the amount of available VRAM by creating a dummy DXGI adapter.
 
 
'''Q:''' How do I run this on Proton/Linux?
 
 
'''A:''' To run on Proton/Linux simply add WINEDLLOVERRIDES="dinput8=n,b" %command% as a launch option. Thanks to [https://github.com/Managor @Managor]

===Film grain noise texture size depends on water quality setting===
{{ii}} This was fixed with Patch 8.
+
{{Image|GTAIV Film grain noise issue.png|Example of film grain effect issue, using <code>Low</code> and <code>Very High</code> '''Water Quality''' settings, respectively.}}
 
+
In "The Lost and the Damned" (TLAD) expansion pack, the size of the noise texture used for the film grain effect is tied to the Water Quality setting and game resolution. This results in the film grain effect being virtually-invisible at the highest settings.

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 importing music files for playback in a custom radio station. Rockstar Games has removed some music tracks from the game due to expired licenses as it has done with Grand Theft Auto: Episodes from Liberty City. See Restore removed music

Visual effect shaders are known to be broken in the PC release when compared to both the Playstation 3 and the Xbox 360 releases.[1] See FusionFix for partial fixes. The game has an extensive modding community, with mod compatibility split between the Complete Edition and older, retail versions. It is also notorious for poor performance (especially on maxed out settings) and frame-pacing issues, even on high-end systems[2]. Lowering settings and/or DXVK are strongly advised.

Rockstar Social Club is not needed to run the game using retail patches 1.0.6.0, 1.0.7.0, or 1.0.8.0.[4]
The Complete Edition includes Grand Theft Auto: Episodes from Liberty City.
The March 2020 update to the Steam version upgraded the game to the Complete Edition, adding achievements, introducing Rockstar Games Launcher DRM and removing multiplayer[5], SecuROM PA DRM and Games for Windows - LIVE DRM entirely (see Network for solutions).
CD keys can be redeemed on the Rockstar Games Launcher to activate the Complete Edition.[6]

DLC and expansion packs

The Complete Edition includes the DLCs now. All previously bought copies on Steam were freely upgraded to that version, and original retail versions can be freely upgraded to the Complete Edition by registering a Games for Windows - LIVE key on Rockstar Games Launcher.

Essential improvements

Patches

Patches after 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[7]
  1. Install DXVK to <path-to-game>\GTAIV.
  2. Create a text file, name it dxvk.conf, and add d3d9.maxFrameLatency = 1 to it to avoid or reduce occasional frame skipping and stuttering[8]
  3. 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.
  4. 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 not use the desired resolution and refresh rate while using DXVK. Use the respective commands to remedy this.[9]

Ultimate ASI Loader

Ultimate ASI Loader is the primary tool used by the game's modding community to allow players to load mods into the game.

Included with FusionFix.
Installation[10]
  1. Download Ultimate-ASI-Loader.zip.
  2. Extract the file to <path-to-game>\GTAIV\.

Note:

Rename the included dinput8.dll file to xlive.dll to disable Games for Windows - LIVE.

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[11]
Includes Ultimate ASI Loader.
Supports both the Complete Edition and retail versions 1.0.7.0 and 1.0.8.0.
Shader fixes and improvements performed utilizing Shader Fixes.
Installation
  1. Go to Releases and download latest version.
  2. Extract the contents of the archive to <path-to-game>\GTAIV\

Issues unresolved

Community-maintained issue database

Timing-related issues

A framerate higher than 60 FPS can result in timing issues, including, but not limited to:
  • Menu fade in/out becomes increasingly longer at framerates above 60
  • In the mission "Out of Commission", while trying to climb onto the helicopter, no matter how often the jump key is pressed, the player character will not be able to get onto the helicopter. Reportedly fixed with patch 1.0.8.0.[26], but may still break above 60 FPS.
  • Brucie's garage door in the mission "Easy as Can Be" closes, prematurely leaving Niko trapped.[27]
  • 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.
  • Several activities, such as pool and air hockey, have their physics break, causing them to not play as expected.
  • The handbrake camera and regular camera movement become excessively slow.
  • The entire game runs faster than normal when above 250 FPS.[28]
  • Cutscenes zoom in above 30 FPS.[29]
  • Postprocessing effects are inconsistent at different framerates.
  • Rain effects are inconsistent on different framerates.
Use FusionFix[30][31]

Note:

Does not completely fix timing-related issues.
Cap frame rate to 60 FPS.[32]

Note:

FusionFix has an in-game FPS toggle, configurable in the in-game Graphics section of Settings.[11]

Issues fixed

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

Apply Language Loader[33]
Requires Ultimate ASI Loader.
  1. Download and extract Language Loader to <path-to-game>\plugins\.
  2. Edit GameLanguageID in IVLanguageLoader.ini to the desired language.

No bullet spread/recoil

Use FusionFix[34]

Note:

Requires 1.0.7.0, 1.0.8.0, or the Complete Edition.
The option is enabled by default, but can be toggled off by changing RecoilFix to 0 in GTAIV.EFLC.FusionFix.ini.

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[35]
  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 1.0.8.0,[36] but may still happen on certain system configurations[37] such as laptops with dual GPU configurations[38], when using wrappers like DXVK.
Use -availablevidmem XXXX.0 command line argument and replace XXXX by the wanted amount of VRAM in MB[39]

Notes

Using any value above 3072.0 on latest Complete Edition version is not recommended as it seems to cause texture popping all throughout the map.[40][dubious – discuss]
Use ExtendVidMem[41]
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 dinput8.dll 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

Install Visual C++ Redistributable 2005 SP1 and .NET 3.5[42]
Remove any administrator compatibility fix from <path-to-game>\GTAIV\GTAIV.exe

All civilian cars are taxis (taxi bug)

Example of a game affected by the "taxi bug".
Example of a game affected by the "taxi bug".

During gameplay with mods, civilian cars can be entirely replaced with taxis.[43][44][45]

Use RIL.Budgeted[46]
  1. Download the mod.
  2. Extract to <path-to-game>\GTAIV.
  3. Open RIL.Budgeted.ini with a text editor.
  4. Find the following line in the opened file: VehicleBudget=40000000
  5. Change 40000000 to 120000000
  6. Save and close the file.

Note:

Requires Ultimate ASI Loader.
FusionFix already includes this mod, edit the value in GTAIV.EFLC.FusionFix.ini instead.[47]
If using IV Tweaker on retail patches, edit the value in IVTweaker.ini instead.[48]
The value given for VehicleBudget should be the size of vehicles.img in bytes (i.e. the 120,000,000 bytes shown in the above instructions is 114.44 MB) plus the combined size in bytes of all vehicle model and texture mods in use. Increase this value if the bug re-occurs. Decrease it if cars stop having engine sounds.
Use Simple Traffic Loader[49]

Note:

Requires Ultimate ASI Loader and any retail version.
Rather than being a direct solution, it's a workaround that completely changes how traffic is handled.
Allows to limit selected cars to specific in-game regions.
Attempting to limit modded cars to specific in-game regions can result in the game world failing to render.[50]

Film grain noise texture size depends on water quality setting

Example of film grain effect issue, using Low and Very High Water Quality settings, respectively.
Example of film grain effect issue, using Low and Very High Water Quality settings, respectively.

In "The Lost and the Damned" (TLAD) expansion pack, the size of the noise texture used for the film grain effect is tied to the Water Quality setting and game resolution. This results in the film grain effect being virtually-invisible at the highest settings.

Use FusionFix[51]

Miscellaneous fixes

Various Fixes, as the mod's name suggests, provides a variety of miscellaneous fixes, such as broken transparencies on various objects and textures, texture and model flickering, missing or incorrect textures (i.e. using beta textures instead of finalized textures as used on console releases), broken LODs, and so on.

The mod also adds textures and assets from various versions of the game where it makes a noticeable visual improvement.

Custom music

The game allows users to play their own music on a custom radio station: Independence FM.[52]

Instructions[52]
  1. Place any audio files/folders or create shortcuts into %USERPROFILE%\Documents\Rockstar Games\GTA IV\User Music\ folder.
  2. Go into the in-game settings.
  3. From the in-game settings, go to Audio.

GTASnP

Gives an incomplete checklist of objectives to reach 100% based on your save.

OpenIV

Used to install mods that are packaged in .oiv format.
Required for mods which expect the user to package their contents into a format usable by the game.

Trainers

Trainers are usually used for fun, but can also add extra features, such as improved FOV settings over FusionFix.

Liberty's Legacy Trainer

Compatible with Complete Edition and retail versions 1.0.7.0 and 1.0.8.0.
aru's Script Hook (additionally, Compatibility Patch for CE if you're using Complete Edition) and ASI Loader are required.

Modifications

Important things to consider

Due to the nature of modding the game, here are some important things to consider before engaging in general (e.g. non-essential) mod installation:

It is strongly recommended to backup any files these mods may replace.
OpenIV may be required for some mods. Such mods do not depend on a specific version unless stated otherwise.
Installing mods that replace files can follow a different procedure which don't require replacing files if you have Ultimate ASI Loader. For example, <path-to-game>\GTAIV\update can include all non-img files in their respective folder structure, while all the .img files can be separately batched into one (or three if they affect EFLC too) .img file with OpenIV in a separate folder.[56]

Improved Animations Pack

Requires OpenIV.
Fixes many issues with gun animations, like the firing delay on the assault rifles.
Ammo depletes much faster on weapons, such as Micro SMG.

Console Visuals

Restores additional console-only visual effects and content.
FusionFix is required.
