amd_fidelityfx_loader_dx12.dll

What Is amd_fidelityfx_loader_dx12.dll?

amd_fidelityfx_loader_dx12.dll is a runtime component used by AMD FidelityFX, a suite of open-source GPU technologies designed to enhance image quality and performance. This specific DLL is the DirectX 12 loader used by games or applications that integrate AMD FidelityFX features.

It is not part of Windows and is not a system DLL. It is bundled directly with games or engines that enable FidelityFX.

What amd_fidelityfx_loader_dx12.dll Is Used For

This DLL initializes and loads FidelityFX effects in DirectX 12 titles. Depending on the game, it may enable:

• FidelityFX Super Resolution (FSR) upscaling
• Contrast Adaptive Sharpening (CAS)
• Ambient Occlusion (CACAO)
• Denoising or post-processing filters
• Optimized compute shader passes

The loader ensures that the game can safely interface with AMD’s effects library using DirectX 12.

It may also:

• Detect GPU capabilities
• Handle device initialization for AMD hardware
• Route FidelityFX shaders to the correct DX12 pipeline

Where amd_fidelityfx_loader_dx12.dll Is Located

Legitimate copies should appear only inside the game or engine directory, typically:

• GameName\amd_fidelityfx_loader_dx12.dll
• GameName\bin\dx12\
• Steam\steamapps\common\GameName\

You should not see this DLL in:

• System32 / SysWOW64
• AppData folders (unless temp extracted)
• Downloads folders

Common amd_fidelityfx_loader_dx12.dll Error Messages

amd_fidelityfx_loader_dx12.dll was not found

The code execution cannot proceed because amd_fidelityfx_loader_dx12.dll is missing

Error loading amd_fidelityfx_loader_dx12.dll

Failed to initialize FidelityFX DX12 runtime

These errors occur when:

• The DLL is missing from the game folder
• Game files are corrupted or partially installed
• The wrong version of FidelityFX runtime is included
• Antivirus quarantined the file
• The game is launched with incompatible DX12 settings

How To Fix amd_fidelityfx_loader_dx12.dll Errors

1. Verify or Repair the Game Installation

This restores the correct FidelityFX components automatically.

• Steam: Properties → Installed Files → Verify integrity
• Epic Games: Manage → Verify
• GOG Galaxy: More → Manage Installation → Verify / Repair

2. Restore the DLL From Antivirus Quarantine

Some AV engines flag shader-related DLLs.

• Check Quarantine / Threat History
• Restore amd_fidelityfx_loader_dx12.dll if listed

After restoring, verify the game again.

3. Update Your GPU Drivers

FidelityFX features rely on modern DirectX 12 support.

Update to the latest drivers:

• AMD Adrenalin for AMD GPUs
• NVIDIA GeForce (FSR-compatible but GPU-agnostic)
• Intel Arc (also supports FSR)

Outdated drivers may prevent FidelityFX initialization.

4. Ensure Your GPU Supports the Feature Used

Although FidelityFX is GPU-agnostic:

• Some effects require DX12 feature level 12_0 or higher
• Integrated GPUs may not support all FidelityFX modules

Lower-end hardware may fail to load the DLL’s required functions.

Manual Installation Notes

If restoring manually:

• Use the DLL only from the game's official files
• Or use a verified copy on DLLme when available

Do not place it in Windows system folders. FidelityFX loaders must reside beside the game executable.

Standalone DLLs from unverified sources may not match your game build and will fail to load.

Security Considerations

A legitimate copy should:

• Come from a game using AMD FidelityFX
• Be located in the game directory
• Have valid metadata (often AMD or the game developer)
• Not be found in random folders

If the DLL appears anywhere outside a game folder, scan it.

Summary

• amd_fidelityfx_loader_dx12.dll is the DirectX 12 loader for AMD FidelityFX technologies.
• It is bundled with games that use AMD FSR, CAS, or other FidelityFX effects.
• Errors are caused by missing files, corrupted installations, outdated GPU drivers, or antivirus interference.
• The correct fix is to verify the game files, update GPU drivers, and restore quarantined files.

If you need a specific version of amd_fidelityfx_loader_dx12.dll, you can request it on the file page to prioritize its upload.
