Installation:

Install using the installer:

  1. Download GTAIV-Remix-CompatibilityMod-1.1.3.zip

  2. Download GTAIV-Remix-CompMod-Installer.exe

  3. Place both files in the same folder (no need to copy them to your game folder) and run GTAIV-Remix-CompMod-Installer.exe

  4. Use the File Dialog to select your GTAIV.exe which is located in your GTAIV install folder

  5. If this is your first time installing, the installer will ask if you want to install a custom Fork of FusionFix
    If you already have FusionFix installed, it's definitely recommended to install this because the original, unmodified version has a few incompatibilities with RTX Remix. If you do not have FusionFix installed, you are free to choose. It's not a requirement.

  6. Make sure that you remove all custom launch arguments for GTAIV in Steam (if you have any set)


OR Install manually (no need to do this if you've used the installer):

  1. Download GTAIV-Remix-CompatibilityMod-1.1.3.zip

  2. Open the zip and extract all files contained inside the GTAIV-Remix-CompatibilityMod folder into your GTAIV directory (next to the GTAIV.exe). Overwrite all when prompted.

  3. If you want to use FusionFix or have it installed already, it's definitely recommended to install my custom fork of FusionFix because the original, unmodified version has a few incompatibilities with RTX Remix.
    You can find the files inside _installer_options/FusionFix_RTXRemixFork. Extract the plugins & update into your GTAIV directory and override any existing files.


Usage and general Info

  • Run the game like normal or use the provided batch files (mentioned in the Wiki further down) if you notice heavy stuttering.

  • It's recommended to adjust distance and quality sliders in the GTA4 graphic options (higher values => earlier CPU bottleneck).
    Try 30 for view distance and 50 for quality and adjust from there. The first launch might cause problems, simply re-try a second time.

    Press Alt + X to open the Remix menu
    Press F4 to open the Compatibility Mod menu
