Reshade Ray Tracing Shader Rtgi 0.33 [top] May 2026
Unlike traditional flat ambient occlusion, the 0.33 build treats contact shadows as a byproduct of ray tracing. This produces deep, physically accurate micro-shadows in corners, foliage, and character clothing. 4. Cross-API Compatibility
The shader, developed by Pascal Gilcher (widely known as Marty McFly ), is a major update that brings real-time, screen-space ray-traced global illumination to older and modern PC games. By physically simulating how light reflects off in-game surfaces, it bridges the gap between traditional rasterized lighting and true hardware ray tracing.
In version 0.33, the RTGI shader pairs with the , which utilizes an optical flow algorithm to generate motion vectors. This dramatically reduces the visual noise and flickering that plagued earlier versions, resulting in much smoother lighting transitions during fast movement. 2. Improved Bounce Light Accuracy Reshade Ray Tracing shader RTGI 0.33
Below is an in-depth breakdown of the shader, its core enhancements, and how to configure it. 💡 What is ReShade RTGI 0.33?
RTGI 0.33 provides more accurate . When a bright light source strikes a red surface, the bounce lighting realistically tints neighboring white or dark walls, creating an incredibly immersive environment. 3. Screen-Space Ambient Occlusion (SSAO) Integration Unlike traditional flat ambient occlusion, the 0
The acronym stands for Ray Traced Global Illumination . It functions within the ReShade post-processing injector to extract depth information directly from the game engine. It then traces rays across those surfaces to calculate bounce lighting and ambient occlusion.
RTGI 0.33 functions across multiple graphics APIs, including DirectX 9, 11, 12, OpenGL, and Vulkan. This enables gamers to add cutting-edge lighting to retro titles like Unreal Tournament or Max Payne as easily as modern games.
