Reshade Ray Tracing Shader Rtgi 0.33 Guide

: RTGI physically simulates light bounces, adding depth to scenes that otherwise look "flat". It adds subtle glow beneath light sources (like portals in ) and accurate shadows at material edges. Performance Cost

Settings have been reorganized inside the ReShade overlay, making it easier for beginners to get great results out of the box. Prerequisites for Using RTGI 0.33

Unlike basic ambient occlusion, which only darkens corners, RTGI calculates bounced light. If a bright red light hits a white concrete wall, the white wall realistically absorbs and reflects a subtle red hue. RTGI 0.33 improves the accuracy of these calculations, eliminating the "glow" artifacts common in older shader versions. 2. Prerequisites and Requirements Reshade Ray Tracing shader RTGI 0.33

If you see "boiling" white noise on faces or walls, reduce your "Ray Count" and increase "TAA Strength" . If you see inverted shadows (light inside dark corners), your depth buffer is reversed—toggle RESHADE_DEPTH_INPUT_IS_REVERSED in the preprocessor definitions.

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. ReShade 5.3 and RTGI 0.33 Update | August 2022 : RTGI physically simulates light bounces, adding depth

The 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.

: Usually caused by a "temporal" setting in the game (like TAA). Try disabling the game's native Anti-Aliasing. Prerequisites for Using RTGI 0

RTGI 0.33 hooks into a game’s depth buffer. This is a grayscale map representing the distance of objects from the camera. The shader casts virtual rays across this depth map. It calculates how light hits surfaces, creates shadows in crevices, and bounces colors onto nearby objects. Key Version 0.33 Enhancements

Expect a 20% to 50% drop in FPS depending on your resolution and ray count. 🚀 How to Optimize Performance Lower Ray Count:
