Vulkan DXVK 2.1 ASYNC Module - Eliminate texture loading lag

🎮 **Test environment**: This module is mainly tested on **nVIDIA graphics card**. Support for **AMD graphics cards** varies and may not work properly.

---

✨ Core Functions

Using **Vulkan DXVK Async** technology, the game finally gets rid of the lag problem when loading textures! 🚀

⚠️ **IMPORTANT**: When this mod is enabled, **DLSS, NVIDIA Low Latency Mode, and Ray Tracing will be disabled**.

🎨 **Enable HDR**: If you want to enable HDR, open the `dxvk.conf` file, find and uncomment (remove the `#` sign) this line: `# dxgi.enableHDR = True`.

📦 Module contains content

This integration package contains the following components:

• Integrated various **Engine.ini file optimization settings** from communities such as Reddit.
• **DXVK 2.1 Async branch** from Ph42oN/dxvk-gplasync.
• **VKD3D** from HansKristian-Work/vkd3d-proton.

📥 Installation Guide

• **Engine.ini file**:
• From the `WindowsNoEditor` folder, copy the `Engine.ini` file to the following directory:

`%AppData%\Local\Hogwarts Legacy\Saved\Config\WindowsNoEditor`

• **or**, you can also use your preferred `Engine.ini` file.

⚠️ **Critical Setting**: If using your own `Engine.ini`, **Make sure** to add the following lines to avoid DXVK crashes when using the "luminos" spell in certain scenarios:

`r.AllowPointLightCubemapShadows=0`

⚠️ **Video memory settings**: If you use the `Engine.ini` provided by the module, please modify the value of `r.Streaming.PoolSize` according to your graphics card memory:

• 6GB VRAM: set to `2048`
• 8GB VRAM: set to `3072`
• 12GB video memory: set to `4096`

• **Core files**:
• From the `Win64` folder, copy `d3d12.dll`, `dxgi.dll`, `dxvk.conf` and `dxvk_config.dll` to the `Win64` directory of the game main program:

`\Hogwarts Legacy\Phoenix\Binaries\Win64`

• **Clear cache**:
• **Delete** all contents within the `%ProgramData%\Hogwarts Legacy` folder. (**VERY IMPORTANT**)

• **First run**:
• Start the game and **wait patiently for the shader compilation to complete**.
• After the first compilation is completed, exit the game and **launch the game again**.

🎉 Now, enjoy a smooth and lag-free experience!

⚙️ Performance Notes

About **FPS (Frame Rate)**:

• If you have an older CPU, this mod may **boost** your FPS.
• If you have a newer CPU, FPS may be slightly lower than when using native DX12, but stuttering will be significantly improved.
• It is recommended that you test it yourself and decide whether to use it.

---

⚠️ Known issues

• **Poor AMD graphics card support**: Does not work properly on the latest RX6xxx series, RX570, RX5700, etc. models. Effects vary from person to person.
• **Launch Crash**: If the game crashes on launch, make sure you **don't press any keys or move the mouse** before the "Press any key" screen appears. This usually solves the problem.

🗑️ Uninstall method

To revert to the original DX12 mode, simply delete all files added by the mod and empty the `%ProgramData%\Hogwarts Legacy` folder again.
