Install it anywhere BUT your Program Files folder. AKA your C drive. Problems booting up are likely related to Windows' file permissions. Make a new folder in another drive of yours and create a new library of it in Steam settings. Or split at least 30GB from your C drive and make a new partition if you only got one drive in your computer.

Drop all the contents from the folder to the folder where GTAIV.exe is found.

That's it. There will be options where you can turn on the console gamma to make the game darker, change tree visuals and such in the Display settings in-game.

I advise capping your FPS to 60, at most 120 if you really want to. Anything higher is guarenteed to cause issues.

FusionFix by default skips the intro/menu when you boot up the game, not letting you change settings before the game even starts.

Go to the plugins folder that came with FusionFix and drop the cfg in there.

DXVK is a translation layer for DirectX games. This significantly improves performance for GTA IV.

Download the latest release, and obtain d3d9.dll and dxgi.dll from the x32 folder and drop it into the folder where GTAIV.exe is found.

You might see some stutters but driving around will let the shaders compile and the experience should be seemless.

As some of you know, Rockstar refuses to renew licenses for certain songs so when they update the game they just remove them entirely.

As of the time I made this guide the Nexus page for this has been hidden for unknown reasons so I still have a archive of it here: https://drive.google.com/file/d/1RQhoTXPDu3hNIpUEFWVnoa473gaGClIx/view?usp=sharing

You will need a file extractor such as 7zip.

Drag the update folder into the same folder where GTAIV.exe is located. Replace when asked and thats it.

This restores certain things, while also improving inconsistencies with textures and such.

Download Installation.through.Fusion.Overloader.2.0.2.rar and in it theres a update folder. Just drag it into the same folder where GTAIV.exe is located.

In my opinion the console loading screens are significantly better than PC's.

Drop the 2 folders in the same directory as where GTAIV.exe is. Replace files when asked to.

This mod aims to restore console assets to PC. I highly recommend it as it looks stunning with FusionFix.

Download whatever you want (preferably all zip files)

Then go into each one you downloaded and drag the update folder to the same folder where GTAIV.exe is located. They all go into FusionFix's update folder so it doesnt actually modify anything.

If you already downloaded the console loading screens stated in last step do not download Console Visuals' loading screens. It will mess up the order of what screens play.

Due to DXVK your VRAM capacity will likely not be seen correctly, defaulting to 512MB and limiting you to medium textures. To fix this right click on GTA IV in Steam and click properties. Then type in the launch options:

-nomemrestrict -norestrictions -availablevidmem XXXX (replace the Xs with the amount of VRAM your GPU has in MB)

Examples-

1024MB (1 GB)
2048MB (2 GB)
4096MB (4 GB)
6144MB (6 GB)
8192MB (8 GB)
16384MB (16 GB)
24576MB (24GB)

Do not max out those distance settings. They go over the engine's limits, no idea why Rockstar even configured it like this.


FusionFix even will warn you on the bottom if you have unrecommended values set.

If you play on a gamepad and playing above 60FPS, you will encounter the handbrake cam bug where it will spin violently. Either cap the game to 60FPS or play on keyboard and mouse as it doesnt happen there.

FusionFix offers toggling console alpha textures and even lighting for trees plus other post processing effects.


I mentioned earlier you can toggle the console gamma as well which makes the game overall darker.

For you borderless users out there, FusionFIx also offers borderless mode. Just enable Windowed and Windowed Borderless and you are good to go.

Congratulations! You are finished and ready to delve into Liberty City. Enjoy.
