This is a generic post-processing injector for games and video software. It exposes an automated way to access both frame color and depth information and a custom shader language called ReShade FX to write effects like ambient occlusion, depth of field, color correction and more which work everywhere.

ReShade can optionally load add-ons, DLLs that make use of the ReShade API to extend functionality of both ReShade and/or the application ReShade is being applied to. To get started on how to write your own add-on, check out the API reference.

The ReShade FX shader compiler contained in this repository is standalone, so can be integrated into other projects as well. Simply add all source/effect_*.* files to your project and use it similar to the fxc example.


You'll need Visual Studio 2017 or higher to build ReShade and Python for the gl3w dependency.

  1. Clone this repository including all Git submodules
  2. Open the Visual Studio solution
  3. Select either the 32-bit or 64-bit target platform and build the solution.
    This will build ReShade and all dependencies. To build the setup tool, first build the Release configuration for both 32-bit and 64-bit targets and only afterwards build the Release Setup configuration (does not matter which target is selected then).

A quick overview of what some of the source code files contain:

File Description
dll_log.cpp Simple file logger implementation
dll_main.cpp Main entry point (and optional test application)
dll_resources.cpp Access to DLL resource data (e.g. built-in shaders)
effect_lexer.cpp Lexical analyzer for C-like languages
effect_parser.cpp Parser for the ReShade FX shader language
effect_preprocessor.cpp C-like preprocessor implementation
hook.cpp Wrapper around MinHook which tracks associated function pointers
hook_manager.cpp Automatic hook installation based on DLL exports
input.cpp Keyboard and mouse input management and window message queue hooks
runtime.cpp Core ReShade runtime including effect and preset management
runtime_gui.cpp Overlay rendering and everything user interface related


Any contributions to the project are welcomed, it's recommended to use GitHub pull requests.
