Grand Theft Auto IV

From PCGamingWiki, the wiki about fixing PC games
This page may require cleanup to meet basic quality standards. The specific problem is: (Mrntptrs1:) Issues need cleanup for fixes that are outdated, have bad layout, unsourced claims or contain incorrect info. Unclear which mods and fixes are compatible with latest Complete Edition version and which requires downgrading. Maybe too many mods are listed; should maybe only list the best mods. DXVK-section needs cleanup and claims need to be better substantiated with user-testing.). You can help by modifying the article. The discussion page may contain useful suggestions.

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, introducing Rockstar Games Launcher DRM while removing Games for Windows - LIVE and SecuROM PA DRM entirely and adding achievements, but also removing multiplayer[3] (see Network for solutions).
Since Patch 6 Rockstar Social Club is no longer required to run the game.[4]

DLC and expansion packs

DLCs are now a part of the Complete Edition. All previously purchased copies on Steam were upgraded for free to that version, while original retail versions can be freely upgraded to Complete Edition, by registering a Games for Windows - LIVE key on Rockstar Games Launcher.

Essential improvements

Patches

Patches after 1.0.8.0 were only released for digital versions of the game..
Patch 8 updates the game to version 1.0.8.0
Patch 7 is also available (may be required for some mods, as much as Patch 4).

Skip intro videos

Edit loadingscreens_pc.dat[5][6]
  1. Go to <path-to-game>\GTAIV\common\data\.
  2. Open loadingscreens_pc.dat with a text editor.
  3. Change the value of "duration" for sections 1, 2, 3, 4, 5, and 6 to "0".
Use GTA IV No-intro Easy Fix
  1. Download and extract the NO-intro_easy-fix.rar file. (Mirror on PCGamingWiki)
  2. Move the loadingscreens_pc.dat file to <path-to-game>\common\data\ (replace the file when prompted).
Apply the GTA IV Intro Patch[citation needed]

Disable Xbox GFWL

Xbox GFWL is no longer included in digital releases.
See XLiveLess / ASI loader[7]

Fix in-game bugs

FusionFix

This projects aims to fix some issues present in the Complete Edition (patches 1.2.0.30 and above).
Requires Ultimate ASI Loader.
Installation[8]
  1. Download the GTAIV.EFLC.FusionFix.zip file.
  2. Extract the files to <path-to-game>\GTAIV\ (replace any file(s) when prompted).

Notes

For patch 1.0.8.0, see here. Otherwise, it is recommended to use ZolikaPatch.

ZolikaPatch

For use with patches 1.0.4.0, 1.0.7.0, and 1.0.8.0. For the Complete Edition (patches 1.2.0.30 and above) see FusionFix.
Requires Ultimate ASI Loader.
This started as a bug fixing mod and added a few graphical overhaul.
Requires downgrading.[citation needed]
Fixes issues that FusionFix doesn't address.
Installation[9]
  1. Download the ZolikaPatch_v6.9.4.zip file.
  2. Extract the files to <path-to-game>\GTAIV\ (replace any file(s) when prompted).

Using DXVK to improve performance

DXVK is a DirectX to Vulkan API translation layer. It may drastically improve performance over older APIs like DirectX 9 due to advanced multithreading support, extended draw call handling capabilities and added shader/state cache systems.
Installation
  1. Download the DXVK files on GitHub.
  2. Extract the file and copy d3d9.dll and dxgi.dll from the x32 folder to <path-to-game>\GTAIV\.
    • Users who experience crashing, freezing, or infinite loading (especially after alt-tabbing or the game otherwise losing focus) should try using DXVK version 1.9.3 or later, as this version has been reported to solve these issues.[10]
    • As of August 2022, some users reported DXVK version 1.9.4 being the most performant for GTA IV, with less overhead on the GPU and causing less stutter when the game engine is under stress (the latest DXVK version at that moment being 1.10.3). [citation needed]

Notes

The game may require more than 2 GB of RAM to avoid stuttering while using wrappers such as DXVK; extending the RAM usage limits is highly recommended, see Use more than 2 GB of RAM.
The game may not detect the correct amount of VRAM available and only show 512 MB instead while using wrappers such as DXVK; see VRAM amount is incorrectly recognized for a fix.
To avoid or reduce occasional stuttering and frame skipping, create a new text file, add d3d9.maxFrameLatency = 1 to it, and save it as dxvk.conf in <path-to-game>\GTAIV\; this command ensures only a single frame is buffered by the CPU ahead of time, also possibly leading to a decrease in input lag in case V-Sync is active.[11]
Adding d3d9.presentInterval = 1 to the dxvk.conf file enables V-Sync; using V-Sync through DXVK may provide less CPU overhead compared to the game's own V-Sync implementation.
Adding d3d9.numBackBuffers = 3 to the dxvk.conf file may further improve frametime stability while using V-Sync; this command ensures Triple Buffering is active.
Using the game's -noprecache command with DXVK is not recommended as it may interfere with its caching system.[12]
Combining DXVK with different wrappers (e.g. DxWrapper) is not recommended as it may negate the performance improvement otherwise brought by the Vulkan API and possibly cause other issues as well (e.g. infinite loading screens and visual issues such as invisible character model).
DXVK can prevent some ENB shaders like global occlusion from caching and rendering.[13]

Additional information

A GPU with Vulkan support is required.
At least 4 physical CPU cores, 8 GB of RAM, and 2 GB of VRAM is recommended.
The game may stutter for a while upon the first run; this is due to the shader/state cache compilation and only temporary.

Anti-aliasing

While not available through DXVK or in-game, anti-aliasing can be added over DXVK by using the SweetFX DLL injector.[14]
  1. Install DXVK into <path-to-game>\GTAIV\ as described above.
  2. Rename the d3d9.dll file to d3d9_dxvk.dll and the dxgi.dll file to dxgi_dxvk.dll.
  3. Download SweetFX 1.4u Boulotaur2024's Injector.[15]
  4. Extract all the contents of the file except for the \X64_dll's folder to <path-to-game>\GTAIV\.
  5. Open SweetFX_settings.txt, and under "Misc settings" at the bottom of the file, set the external wrapper settings to the following:
    // external_d3d9_wrapper = d3d9_dxvk.dll
    // external_dxgi_wrapper = dxgi_dxvk.dll
    
  6. Save the file and launch the game.
Both SMAA and FXAA are available.
The anti-aliasing levels, among other features, can be adjusted in SweetFX_settings.txt under "SMAA Anti-aliasing settings" and "FXAA Anti-aliasing settings".
Use the Insert key to toggle SweetFX entirely, the End key to create a screenshot, and the Delete key to reload SweetFX.

  • -minspecaudio: forces lower quality audio - good for lower-end processors (while it doesn't decrease the definition of the audio, some extra audio details were removed, therefore reducing CPU load).
The game uses DirectSound[20] which can be handled by Creative Alchemy (set duration to 10).[21] Just run LaunchGTAIV.exe as administrator just in case the game crashes (unnecessary in Rockstar Launcher version).

DSOAL for using as alternative DirectSound wrapper (with or without HRTF) is compatible with the Rockstar Games Launcher version and with Windows 10 builds lower than at least 1809.

In case of old versions - for Games for Windows - LIVE on Windows 8 or later, install the latest Games for Windows - LIVE.

Unable to play in Offline Mode with the Steam version of the game

This solution will enable offline mode with local game saves.

Launch the game from the Rockstar Games Launcher[23]
  1. Make sure both Steam and Rockstar Games Launcher are already set for offline mode: Steam's how-to. Rockstar Games Launcher's how-to.
  2. Disconnect the system from Ethernet and Wi-Fi.
  3. Launch the Rockstar Games Launcher using Windows' Start Menu, which uses a shortcut to "LauncherPatcher.exe" (usually located in "%PROGRAMFILES%\Rockstar Games\Launcher")
  4. Launch the game from this launcher by clicking on "Play on Steam".

Fatal error: RMN20

Whole error: GTA IV FATAL ERROR: Windows Vista: Need to have Service Pack 1 or higher to proceed[24]

  2. Click on Right Trigger and bind Soft Pull Action to Right Trigger.

Texture popping, stuttering and other performance issues after running the game for a while

Force maximum available memory[28]
  1. Create a file named commandline.txt in the game's root folder.
  2. Depending on the texture quality set, enter one of the following codes in to the newly created file:
    • 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 launch the game.
Forcing available memory with Patch 1.0.8.0 is not recommended as it will make the game unstable.[citation needed]

No recoil/bullet spread

By default, recoil/bullet spread is only enabled when playing with a controller.[citation needed] This results in 100% shooting accuracy when using a keyboard and a mouse.
Apply FusionFix[29]
Compatible with Complete Edition.

Many mods for GTA IV won't work with the latest version
The most supported versions for modding are any versions between 1.0.4.0 and 1.0.7.0
ENB Series graphical enhancement was never meant to work with anything above patch 1.0.4.0[48] and the particular ENB version needs to support 1.0.8.0 (so also dax.dll fix included (IV | EFLC), otherwise the game may display a black screen. Additionally, for RGL/Steam version this instruction is necessary to fix Social Club error.
Steam Guide for downgrading Complete Edition to 1.0.8.0, 1.0.7.0 or 1.0.4.0

Notes

Has a beginner-friendly installer with a guide.
Can keep Steam Achievements, DLCs in one game and the 3 EFLC-exclusive radio stations.
Is compatible with multiplayer clients and GFWL (To enable GFWL, delete xlive.dll from the game folder, delete XlivelessAddon.asi from the plugins folder and get the GFWL code protection disabler).
Alternatively, it is possible to play Singleplayer without any requirements for GFWL thanks to xlive.dll.
Downgrading to 1.0.4.0 doesn't have support for DLCs.
Delete any plugins such as FusionFix from the game folder before using this method.
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 version of ScriptHook is required for modding on Patch 1.0.4.0, found here
This version is claimed to have improved game performance[49][50]
Some mods work only with Patch 1.0.4.0, while other mods, such as ColAccel, won't work with Patch 1.0.4.0 at all
Install Patch 7 (1.0.7.0)
  1. Extract the files.
  2. Run UpdateTitle.exe and install it.
  3. Download and install XLiveLess.

Notes

Patch 1.0.7.0 has enhanced graphics, secondary key-bindings, several bug fixes, support for the DLCs and more
Many have reported a performance decrease in this patch in comparison to patches prior to 1.0.6.0. This is because the shadow quality has been improved in 1.0.6.0 and later.
This only works when downgrading from 1.0.8.0 to 1.0.7.0.
