(For my future reference) Getting GTA IV To Run Properly

As the title states, this is mostly for my future reference as I'm going to be upgrading computers in a month or so. I've tried many ways of getting this game to run correctly, and this is what has worked the best for me.

Intro

I've tried multiple guides to try to get this god forsaken game to actually run and be playable, some stuff has worked and some stuff hasn't. This is just a compilation of stuff that I've tried and has worked for me, mostly for future reference because I'm upgrading my computers pretty soon and I still want an enjoyable experience playing this game on my new computer. No explanations because I'm lazy, don't remember, and it's not important for me.

These are the current specs of the computer I am using:

Core i7 4770 (4 core, 8 thread, base clock 3.4GHz, turbo clock 3.9GHz)
NVIDIA GeForce GTX 1060 6GB
16GB DDR4 RAM
128GB SSD (Boot)
1TB HDD

In-Game Graphics Settings

Texture Quality - High
Reflection Resolution - Very High
Water Quality - Very High
Shadow Quality - Very High
Night Shadows - Off
Texture Filter Quality - Anisotropic x16
View Distance - 40
Detail Distance - 40
Vehicle Density - 100
Definition - On
VSync - Off

stream.ini

1. Navigate to \GTA IV\pc\
   
2. Open "stream.ini"
   
3. Replace every 204800 with 409600
   
4. After saving and closing, copy and paste "stream.ini" into the main GTA IV install directory*

This is what it should look like when done:

virtual		409600
physical	409600
virtual_optimised	409600
physical_optimised	409600

*May not be necessary, this is more of a just in case thing I guess

LAA 4GB Memory Patch

The LAA 4GB memory patch can be found here.[ntcore.com] Thank you to MythAlex for the new link.

1. Run "4gb_patch.exe" located in the downloaded .zip
   
2. Select "gtaiv.exe" in your main install directory and patch it
   
3. After "gtaiv.exe" is patched, right click it and click "Properties"
   
4. Navigate to "Compatibility" and tick "Disable fullscreen optimizations"

DXVK Vulkan Wrapper

The DXVK Vulkan wrapper can be found here.[github.com]

1. Download the latest version of the Vulkan wrapper
   
2. In the downloaded .zip file, navigate to the x32 folder specifically, not x64. x64 will cause game crashes because GTA IV is a 32 bit application
   
3. In the x32 folder, copy "d3d9.dll" and "dxgi.dll" to your main GTA IV install directory

Disable Shader Pre-Caching in Steam

This is (apparantly) required for the DXVK Vulkan wrapper.

1. In Steam, click the Steam drop down menu at the top left and open settings
   
2. Select Shader Pre-Caching at the bottom
   
3. Untick Enable Shader Pre-Caching

NVIDIA Control Panel

This is courtesy of somebbq and Punkamania. Punkamania's settings were tried first, then somebbq's settings were. Honestly have no clue what will be better with my new computer.

1. Open the NVIDIA control panel
   
2. In the left menu under "3D Settings", select "Manage 3D settings"
   
3. In the 3D settings, select the "Program Settings" menu
   
4. Select "Add" and add "Grand Theft Auto 4 (gtaiv.exe)"

The following are the settings I'm using in the control panel:

Do not set FPS above 60.

i also install the liberty's legacy trainer, just have to make sure you use the complete edition patched scripthook

[ඞඞඞඞඞඞඞඞඞ]

wouldnt even bother downgrading, just install fusion fix and a couple other game enhancements you can find in the recommended mods section of the forum post for it. that and dxvk async

[Still Alive]

this guide covers everything needed to run the game well https://steamcommunity.com/sharedfiles/filedetails/?id=2850546763

[ඞඞඞඞඞඞඞඞඞ]

one of the biggest issues is the game was just poorly ported to pc to begin with. the game runs differently for pretty much every single hardware configuration

[ඞඞඞඞඞඞඞඞඞ]

honestly i think i might delete this and write a new one for people who dont even know where to begin. love this game and want people to be able to enjoy it lol

[ඞඞඞඞඞඞඞඞඞ]

this guide was honestly outdated when i wrote it, and i didnt even know it. if you just want to play the complete edition and dont really want to get into modding, try fusion fix https://github.com/ThirteenAG/GTAIV.EFLC.FusionFix

[michaellacelle8]

My problem is that whenever i get onbto the game its really laggy when im in the menu and super slow to load to stuff like fast traveling in a taxi or going in and out of cut scenes and stuff like that it takes like 25 minutes just to get into the game and takes a bit to get out of the safe house but it has normal FPS outside of cutscenes so i dont know why please help me.

[ඞඞඞඞඞඞඞඞඞ]

im so glad i posted this lol i just came back after two upgrades and was just like "why am i struggling to hit 60fps?" lol big difference now compared to when i made this guide
