ReShade is an advanced post-processing injector. It features its very own effect language, based on HLSL, which not only makes API and platform independent shaders possible, but also introduces a wide range of useful features designed especially for post-processing effect development.
In contrast to all the existing injectors ReShade was written to be completly generic: it itself does not come with any effects, it's a toolset for shader developers to realize their very own imagination.
Define and use your own textures right in the shader code, request custom timers etc., retrieve access to every game's color and depthbuffer (which ReShade is able to genericly identify and hook across games without any extra configuration), no matter if it renders with Direct3D8 (which is wrapped to Direct3D9 to allow using higher shadermodels), Direct3D9, Direct3D10, Direct3D11 or OpenGL (and in both 32bit and 64bit). A highly advanced dynamic hooking system is reponsible for keeping track of the APIs. And because ReShade as mentioned comes with its own shader transpiler, shaders written once work in all five.
