Reshade Ray Tracing Shader Rtgi 0.33 !new! <2026 Release>

The RTGI (Ray Traced Global Illumination) shader by Pascal Gilcher (Marty McFly) is a post-processing tool for ReShade that simulates path-traced lighting, shadows, and ambient occlusion in almost any DX9, DX11, DX12, or Vulkan game.

Future Developments

The Bottom Line: You don't use RTGI 0.33 to beat Alan Wake 2. You use it to make Mass Effect 2 look like it was released yesterday. Reshade Ray Tracing shader RTGI 0.33

Screen Space Only: It can only calculate lighting for objects currently visible on your screen. If a light source or an object is behind the camera or off-screen, it cannot contribute to the lighting. The RTGI (Ray Traced Global Illumination) shader by

Part 1: What Exactly is RTGI 0.33?

To understand the hype, you must first understand the acronyms. RTGI stands for Ray Traced Global Illumination. In real-world terms, this is the light that bounces off a red wall and tints the white floor pink, or the soft shadow under a table that isn't directly lit by the sun.

2. Performance Perks

Marty has optimized the compute shaders. On an RTX 3060 or RX 6700, the performance hit is still noticeable (expect a 15-30% FPS drop depending on your resolution), but it is smoother than previous builds. 0.33 feels leaner, allowing for lower "Ray Length" settings without breaking the ambient occlusion.

Key Features of Version 0.33 Version 0.33 is not just a minor update; it refines the core architecture of the shader significantly.
