The keyword "free" requires a critical discussion. While the shader is open-source in its legacy forms, we will clarify the difference between the free version (0.33) and the paid "Martymod" version.
ReShade is a free and open-source post-processing injector that works as a universal graphics enhancement tool for DirectX, OpenGL, and Vulkan games. It allows you to apply custom shaders to nearly any game, effectively transforming its visuals by adding effects like ambient occlusion, color correction, depth of field, and, most importantly, real-time ray-traced global illumination (RTGI). The easiest way to set it up is by downloading the latest version from the official website . reshade ray tracing shader rtgi 033 free
