Third-Party Notices

ReShade

Shader header files from the crosire/reshade-shaders repository are covered by the same notice.

ReShade's own program file (d3d12.dll or dxgi.dll, as the package installs it) contains further third-party components, and carries their licence texts itself: they are on ReShade's About tab. They are: MinHook (Tsuda Kageyu), including the Hacker Disassembler Engine (Vyacheslav Patkov); Dear ImGui (Omar Cornut); ImGuiColorTextEdit (BalazsJako); stb_image and stb_image_write (Sean Barrett); DDS loading from SOIL (Jonathan "lonesock" Dummer); fpng (Rich Geldreich); SPIR-V, OpenXR and the Vulkan headers (The Khronos Group); OpenVR (Valve Corporation); Vulkan Memory Allocator (Advanced Micro Devices); glad (David Herberth); the libjxl simple lossless encoder (the JPEG XL Project Authors); the Solarized colours (Ethan Schoonover); and the Fork Awesome font (SIL Open Font License).

CodeWalker / OIV Package Installer

CodeWalker, by dexyfex: https://github.com/dexyfex/CodeWalker
The fork the OIV Package Installer is built from, including its source: https://github.com/crxhvrd/CodeWalkerProjects
OIV Package Installer project page: https://www.gta5-mods.com/tools/oiv-package-installer

CodeWalker is published without a licence — all rights reserved by its author. Nothing about it being publicly readable places it in the public domain, and no right to use, modify or redistribute it arises automatically.

The OIV Package Installer is included with dexyfex's approval. That approval covers CoreFX and this use. It grants you nothing: the presence of the installer in a CoreFX package does not license you to extract it, redistribute it, build on it or reuse any part of CodeWalker. For any of that, ask dexyfex.

The OIV Package Installer is free, and its source is public in the fork linked above.

NVIDIA Real-Time Denoisers (NRD) and NVIDIA Render Interface (NRI)

NRD 4.18.0 denoises CoreFX's ray-traced lighting through NRI 181: in GTA V Enhanced (the Denoiser setting's NRD choice, and the RT sun shadow with any denoiser) and in GTA V Legacy (all of FXRT). Both are built into CoreFX.addon64 in object code form; no NVIDIA file ships on its own.

Three more libraries come in with them, also built into CoreFX.addon64, all under the MIT licence quoted below:

MathLib: Copyright (c) 2021, NVIDIA CORPORATION. All rights reserved. https://github.com/NVIDIA-RTX/MathLib
ShaderMake: Copyright (c) 2014-2023, NVIDIA CORPORATION. All rights reserved. https://github.com/NVIDIA-RTX/ShaderMake
D3D12 Memory Allocator: Copyright (c) 2019-2026 Advanced Micro Devices, Inc. All rights reserved. https://github.com/GPUOpen-LibrariesAndSDKs/D3D12MemoryAllocator

This software contains source code provided by NVIDIA Corporation.

NRD is used under the NVIDIA RTX SDKs License (the LICENSE.txt in the repository above). NVIDIA keeps all rights in NRD; using it as part of CoreFX gives you no right to use, copy or distribute it on its own. NRI is used under the MIT licence:

NVIDIA DLSS and Streamline

The Denoiser setting's Ray Reconstruction choice runs NVIDIA DLSS Ray Reconstruction, through the NGX interface of the DLSS SDK (310.9.1), in place of the game's own DLSS call (which reaches DLSS through Streamline). Parts of the DLSS SDK and of Streamline's headers are built into CoreFX.addon64 in object code form. CoreFX for GTA V Enhanced ships no NVIDIA runtime files: nvngx_dlssd.dll and the game's DLSS files come from NVIDIA and from the game.

In GTA V Legacy, CoreFX's DLSS upscaling and anti-aliasing runs through the same interface, and the Legacy package ships NVIDIA's nvngx_dlss.dll unmodified, in CoreFX\Libraries\DLSS.

This software contains source code provided by NVIDIA Corporation.

The DLSS SDK is used under the NVIDIA RTX SDKs License (the LICENSE.txt in the repository above). NVIDIA keeps all rights in the DLSS SDK; using it as part of CoreFX gives you no right to use, copy or distribute it on its own. NVIDIA, the NVIDIA logo and DLSS are trademarks and/or registered trademarks of NVIDIA Corporation in the U.S. and other countries. Streamline is used under the MIT licence:

AMD FidelityFX SDK — FSR and FSR Ray Regeneration

amd_fidelityfx_loader_dx12.dll and amd_fidelityfx_denoiser_dx12.dll are AMD's signed binaries from FSR SDK 2.3.0, shipped unmodified. CoreFX loads them for the Denoiser setting's FSR Ray Regeneration choice. amd_fidelityfx_dx12.dll is AMD's signed binary from FidelityFX SDK 1.1.4, shipped unmodified: CoreFX for GTA V Legacy loads it for FSR.

Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions:

Microsoft DirectX 12 Agility SDK

D3D12Core.dll (CoreFX\Libraries\FSR\D3D12) is Microsoft's binary from Agility SDK 1.614.1, shipped unmodified. CoreFX for GTA V Legacy loads it for FSR. Microsoft's licence terms govern it: they are not replaced or changed by CoreFX's licence.

Dear ImGui

Used by CloudBuilder. The permission notice is the MIT text quoted under AMD FidelityFX SDK above. Dear ImGui includes stb_truetype, stb_rect_pack and stb_textedit (Sean Barrett: public domain or MIT) and the ProggyClean font (Tristan Grimmer: MIT).

JSON for Modern C++

Used by CoreFX and CloudBuilder. The permission notice is the MIT text quoted under AMD FidelityFX SDK above.

Microsoft Detours

Built into CoreFX.addon64, where it hooks the game's calls. The permission notice is the MIT text quoted under AMD FidelityFX SDK above.

darktable Uniform Color Space

Part of the RenoDX shader library that CoreFX's shaders are built with. Its author's addenda ask that any reuse name the author, the project and the source, as above, and that any implementation of this colour space be called "darktable Uniform Color Space" or "darktable UCS" in the software's user interface. The permission notice is the MIT text quoted under AMD FidelityFX SDK above.

frozen and gtl

Constant lookup tables and hash maps, built into CoreFX.addon64, unmodified:

CoreFX shaders

The shaders in CoreFX are its own work. This includes our encrypted ReShade shaders, which ship in a packed format — they are CoreFX shaders, not third-party shaders under another name.

Where a CoreFX shader implements a rendering technique described in a published paper, talk or article, it is an implementation of that technique, not a copy of anyone's code. Techniques are described publicly to be used; copyright covers the code that expresses them, and that code here is ours. No third-party shader code is redistributed in CoreFX, so no notice is owed for any of it.
