Installation

This is a step-by-step guide to installing GTA 5 Redux. Follow the steps in order, starting from a fresh, unmodded copy of GTA V.

Skipping steps or installing out of order is the most common cause of install issues - follow all of them, in order.

Before You Start

A legitimate copy of Grand Theft Auto 5 Legacy (Steam or Rockstar Warehouse - pirated copies are not supported)
OpenIV installed
BattlEye disabled for Story Mode (see the ASI Loader step below - required, or the game won’t load mods)
A minimum of 70GB extra disk space available
A PC that can comfortably run GTA 5 vanilla at a decent FPS

GTA 5 Redux only works with the Legacy version of GTA 5, not Rockstar’s 2025 Enhanced Edition re-release - OpenIV does not support Enhanced.

GTA 5 Redux is installed into a mods folder, separate from your original game files, so you can still access GTA Online and uninstall it cleanly.

GTA 5 Redux improves graphics, so expect a frame drop of around 5-15 FPS compared to vanilla (depending on the ReShade preset selected).

Install OpenIV

OpenIV is the tool used to install GTA 5 Redux.

Download OpenIV

Download the latest version of OpenIV, then run the installer.

Start OpenIV

Open OpenIV and select Grand Theft Auto V Windows.

Select your GTA V install folder:

Rockstar Warehouse: C:\Program Files (x86)\Rockstar Games

Steam: C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto V

Continue to the end of the wizard.

Install ASI

The ASI Loader lets custom mods load into GTA V, and creates the mods folder that Redux installs into.

Click Tools > ASI Manager, then install ASI Loader and OpenIV.ASI.

Disable BattlEye before you launch, or the game will refuse to load mods.
The ASI Loader works by replacing dinput8.dll, a file Windows normally loads as part of DirectInput - that’s how it gets Redux’s mod files into the game. Rockstar’s BattlEye anti-cheat blocks this on sight. If you see a “BattlEye Launcher” window and a message like Blocked loading of file: "...dinput8.dll", that’s what’s happening.
Mods are only safe in Story Mode, never GTA Online. To turn BattlEye off for Story Mode, open the Rockstar Games Launcher, go to Settings, and disable BattlEye (or add -nobattleye to the game’s launch options) - then launch Story Mode specifically, not “Grand Theft Auto Online”.
Before you ever go back online, re-enable BattlEye and remove dinput8.dll and any other mod-loader files - taking modded content into GTA Online risks a ban.

Install GTA 5 Redux

Before you continue, make sure you have a 100% clean, un-modded install of GTA V.
Tip: You can verify your game files are unmodified using Steam’s verify integrity feature or the Rockstar Games Launcher’s verify option.

Get the latest version of GTA 5 Redux from the download page.

The Direct download button gives you the .oiv file directly, ready to open in OpenIV with no extraction needed. The torrent option downloads the same .oiv.

Open OpenIV and select Tools > Package Installer.

Locate the GTA5_REDUX_v1.X.oiv file you downloaded and open it to begin the installation.

Click Install, and choose the option to install into the mods folder.

The installer will copy all the required files - this can take a while.

Once it’s done, you can launch GTA 5 Redux directly from the installer to test it. If everything installed correctly, you’ll see the GTA 5 Redux intro video when GTA V loads.

ReShade Installation

ReShade adds visual presets you can choose between to change GTA 5 Redux’s look. It’s optional - ReShade can occasionally cause crashes for some users, and GTA 5 Redux still works fine without it.

Download ReShade from the official website and run the installer.

Select Click here to select a game and manage its ReShade installation.

Click Browse..., then navigate to your Grand Theft Auto V folder and select GTA5.exe:

Rockstar Warehouse: C:\Program Files (x86)\Rockstar Games

Steam: C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto V

Tick Legacy standard effects - the Redux ReShade presets need it, despite the checkbox’s own hint that it’s only for old presets.

Download the ReShade presets (a separate small download from the main mod).

Extract it, then copy the .ini files from the GTA_5_REDUX_RESHADE folder to your main GTA V folder.

Choosing a ReShade Preset

ReShade presets are chosen from the in-game ReShade menu, which opens automatically when GTA V starts.

Press Home to bring up the preset drop-down and pick one.

Uninstall

To remove GTA 5 Redux, delete the mods folder in your GTA V folder.

Note: this also removes any other mods you have installed there.
