DXVK for Grand Theft Auto IV:

Game version: GTA 4 / Grand Theft Auto IV: The Complete Edition – v1.2.0.43.

DXVK is a Vulkan-based translation layer for DirectX 9/10/11, allowing the game to utilize Vulkan API instead of older DirectX APIs, potentially improving performance and compatibility, especially on integrated GPUs like Intel Iris Xe. Here’s how you can install and use it with GTA IV:

Steps to Install DXVK for GTA IV:

1. Download DXVK:

Visit the DXVK GitHub Releases page.
https://github.com/doitsujin/dxvk

Contribution for the modders Philip Rebohle.

Download the latest DXVK .tar.gz or zip file.

2. Extract DXVK:

Extract the downloaded archive to a folder on your computer.

You’ll find two folders: x32 and x64, corresponding to 32-bit and 64-bit games.

3. Identify GTA IV’s Executable Architecture:

GTA IV is a 64-bit game, so use the contents of the x64 folder.

4. Locate the GTA IV Installation Directory:

Go to the folder where GTA IV is installed. For example:

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

5. Copy DXVK Files:

Copy the following files from the x64 folder:

d3d9.dll

dxgi.dll

Paste these into the same directory as GTA IV's executable (GTAIV.exe).

6. Verify Vulkan Runtime Installation:

Ensure that Vulkan runtime libraries are installed on your system. Most systems with Iris Xe already have Vulkan support. If not, download the latest Intel GPU drivers.

7. Run the Game:

Launch GTA IV. DXVK should now be active.

To confirm DXVK is working, look for a dxvk.log file in the game's folder after running the game.

Difference Between DXVK and DirectX 9 on Iris Xe:

DirectX 9:

Uses an older rendering API designed for traditional, fixed-function pipelines.

On modern GPUs like the Intel Iris Xe, it relies on software layers for compatibility, which can lead to suboptimal performance and higher CPU usage.

Limited multithreading capabilities.

Lacks support for modern graphical optimizations and hardware acceleration.


DXVK:

Translates DirectX 9 calls into Vulkan, a modern graphics API optimized for current hardware.

Takes advantage of multithreading, reducing CPU overhead.

Improves performance, especially on integrated GPUs like Iris Xe, where Vulkan has better driver support.

Provides smoother frame rates and better resource management.

May resolve compatibility issues in some games when running on modern hardware.

Why DXVK is Beneficial for GTA IV on Iris Xe:

1. Improved FPS: DXVK reduces the CPU bottleneck, leading to better frame rates on Iris Xe.


2. Stability: Vulkan drivers are often more stable than legacy DirectX 9 on modern GPUs.


3. Compatibility: Some graphical glitches or stutters common in DX9 games can be mitigated.


4. Future-Proofing: Vulkan ensures the game runs better on new hardware and operating systems.
