Grand Theft Auto IV

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. 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 is incompatible with a lot of modifications so a downgrade to patch 1.0.4.0, 1.0.7.0 or 1.0.8.0 is strongly recommended if you plan to use global mods.

Patch 1.0.4.0 is recommended for ENB visual mods, 1.0.7.0 for overall mod compatibility and patch 1.0.8.0 haves the most stable performance but there's a rare issue/bug which makes patch 1.0.8.0 run way worse compared to other patches.

Patch 1.0.7.0 and 1.0.8.0 restores multiplayer which is still available to play. Patch 1.0.4.0 also supports multiplayer with this mod but you won't be able to play with patch 1.0.7.0 and 1.0.8.0 users.

Patch 1.0.4.0 doesn't have EFLC support so you can only play the original game but not the DLC's.

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.

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

Clarification the mission A Revenger's Tragedy at the launch of the game was breaking when playing at more than 30fps, but a patch released in 2016 (1.0.8.0) fixed the problem and now you can play at 60fps perfectly

Cap frame rate to 60 FPS (if using FusionFix you can set a framerate cap in-game by going to Display tab)

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)

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

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
Works on the Complete Edition.

Apply Bullet Spread/Recoil Fix script
Requires an ASI Loader. Not recommended to use in Multiplayer. Isn't compatible with Complete Edition - use FusionFix instead

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
Create a file named commandline.txt in the game's root folder. 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 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

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.

Simply place any audio files/folders or create shortcuts in the %USERPROFILE%\Documents\Rockstar Games\GTA IV\User Music\ folder and tune into the station in-game.

iTunes must be installed for M4A support.

Supported formats are M4A, MP3 and WMA. Other formats and extensions are not detected.

Use shortcuts to audio files/folders to improve performance and save disk space.

Supports Surround audio files. Up to 6 channels.

FLAC is not supported. Convert them to WMA Lossless to use them in-game.

Monaural audio files are not supported.

Reduce loading times

Place ColAccel script in <path-to-game>
Requires an ASI Loader. Supports the Complete Edition. Greatly reduces loading times. Patch 1.0.4.0 is not supported. Produces memory issues on some PC's. May cause bugs and/or other inconsistencies, mostly related to scripted models or objects that alter their appearance via story progression.

Restore removed music

Over 50 radio station tracks were removed from the game in April 2018 due to expired licenses.

Downgrading the Radio Stations
Download the (music) downgrader. Unpack to the installation folder. 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
Download the Ultimate-ASI-Loader.zip file. 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
Go to <path-to-game>\GTA IV\pc\ and open the stream.ini file. 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.

Installation
Download the XLivelessAddon.zip file. Extract the contents of the download to <path-to-game> (replace the file when prompted).

Make sure to set everything inside XLivelessAddon.ini to 0 to make it compatible with ZolikaPatch.

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.

Install DXVK

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. 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.

Modmenus

A modmenu is extremely reccomended for multiplayer play.

ZMenuIV

Biggest modmenu for GTA IV.

Includes a lot of useful options.

Multiplayer-focused - highly reccomended for multiplayer.

Includes a Chaos mod for streamers and fun.

Not compatible with Complete Edition

Liberty's Legacy Trainer=

One of the few modmenus that are compatible with Complete Edition.

Requires ScriptHook Compatibility Patch for CE.

Smaller than ZMenuIV.

ENBSeries graphic modifications

Popular modification amongst mod creator, YouTuber and other content creators.

ENB Series graphical enhancement was never meant to work on Version 1.0.5.0 or later, 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.
