Reshade Ray Tracing Shader Rtgi 033 2021 Fixed

: The core feature simulates how light bounces off surfaces, picking up colors and casting them onto surrounding objects. This adds a level of depth and realism to older titles that typically rely on static, pre-computed lighting. Infinite Ray Length Multiplier

So, why does v0.33 hold a special place in the community’s heart? Released in 2021, this version arrived at a perfect moment for stability and accessibility.

Place the RTGI .fx file into the reshade-shaders/Shaders folder and the accompanying textures into reshade-shaders/Textures .

Sets the number of rays launched per pixel. Keep this at 3 or 4 for gameplay. Move it to 7+ only for taking screenshots. reshade ray tracing shader rtgi 033 2021

Ensure "Copy depth buffer before clear operations" is checked.

Real-time ray tracing used to require expensive, top-tier graphics cards. Pascal Gilcher changed this landscape by introducing his Ray-Traced Global Illumination (RTGI) shader for ReShade. The release of version 0.33 in 2021 marked a major milestone for this software. It brought optimized performance and stunning visual depth to thousands of older DirectX 9, 11, 12, and Vulkan titles.

| Parameter | Function | | :--- | :--- | | | Maximum distance a ray travels to find a surface. Higher = more bounce light but more performance cost. | | Intensity | Strength of the indirect lighting contribution. | | Bounce Count (Hidden) | Fixed in v0.33 to 1-2 bounces for performance reasons. | | Temporal Factor | How much the current frame blends with previous frames to reduce noise. | | Quality Mode | Low (performance) vs. High (visuals). High used 4 rays per pixel. | | AO Mix | Blends traditional ambient occlusion with ray traced AO for cleaner shadows. | : The core feature simulates how light bounces

: Controls how far each ray travels. A value between 10 and 15 offers great accuracy without tanking performance. Lighting and Filter Controls

In 2021, the ReShade RTGI (Ray Traced Global Illumination) shader, developed by Pascal Gilcher (Marty McFly), was a transformative post-processing tool that brought advanced lighting effects to games without native ray tracing support. Version

: This feature uses the screen's existing image to inform the ray tracing calculations, helping the added lighting feel more cohesive with the game's native art style. Hardware Independence Released in 2021, this version arrived at a

Kira smiled when she read it. In the end, the shader did what great small tools do: it invited attention. A ripple of simulated photons had illuminated not just pixels but a community that cared about light, craft, and the little human scale moments shading could reveal.

Unlike 2023’s RTGI 1.0 (which required a paid Patreon sub for early access), on GitHub and community forums, cementing its legacy.

RTGI was not using DXR or Vulkan ray tracing extensions. That meant AMD GCN cards and even Intel integrated graphics (with very low settings) could run it – a major democratization of ray tracing.
