RTGI stands for . It is a premium shader developed by Pascal Gilcher (known online as Marty McFly) distributed primarily through his Patreon community.
In the context of ReShade modification, a "patched" version typically refers to a shader configuration modified for universal compatibility. Standard RTGI shaders require access to a game's depth buffer.
RTGI is a custom shader designed for ReShade, a popular post-processing injection tool. Created by renowned modder Pascal Gilcher, also known as Marty McFly, its purpose is deceptively simple yet technically profound: to add fully dynamic, realistic, and immersive ray-traced lighting to video games that were never designed to have it.
Ray tracing is computationally expensive. Because ReShade injects RTGI at the screen-space level without deep game-engine optimization, it requires a robust PC build to maintain stable frame rates.

"Patched" versions shared on sketchy file-hosting websites are rarely maintained. They frequently contain broken, stripped-down pre-processor code that triggers memory leaks, engine micro-stutters, or outright crashes back to the desktop when paired with newer versions of the core ReShade Repository . 3.

Launch your game and press the key to open the ReShade overlay. Check the box next to qUINT_rtgi . Navigate to the Add-ons tab in the ReShade menu.
| Game | Effect of RTGI 0.33 | Performance Hit | | :--- | :--- | :--- | | (with ENB) | Completely transforms dungeons and forests. Light properly fills interiors. | Medium (15-20% FPS drop) | | Fallout 4 | Fixes the flat, gray ambient lighting. Makes settlements feel alive. | Medium | | Mass Effect Legendary | Subtle but gorgeous. Light bouncing off armor and ship walls. | Low (5-10%) | | Dark Souls 3 | Removes the need for screen-space ambient occlusion (SSAO). Adds depth to cathedrals. | Low | | GTA V | Outdoors is minimal benefit, but interiors of buildings pop dramatically. | Medium | | Minecraft (Java + OptiFine) | Yes, it works. Ray-traced GI without needing a PTGI shader. | High (Use with Iris mod for best results) | RTGI stands for
Pascal Gilcher develops the RTGI shader as a premium tool, traditionally hosting beta versions behind a Patreon paywall. Version 0.33 represents a highly stable, feature-rich release optimized for modern graphics cards. What Does "Patched" Mean?
Video game visuals evolve at a breakneck pace, yet many classic and modern titles lack native support for advanced ray tracing. Ray Tracing Global Illumination (RTGI), a groundbreaking screen-space ray tracing shader created by Pascal Gilcher (Marty McFly), changes this entirely. By injecting path-traced lighting, ambient occlusion, and physical reflections into almost any 3D game, RTGI transforms flat imagery into cinematic masterpieces.

Downloading patched shaders from unverified third-party forums, YouTube descriptions, or file-sharing sites poses significant security risks. Malicious actors frequently package malware, crypto-miners, and trojans into archives labeled "reshade rtgi 033 download patched."

Early beta versions of RTGI contained expiration dates or hardware identification checks. A patched version removes these lines of code so the legacy shader remains functional indefinitely. Key Features of RTGI 0.33 Description Visual Impact Colors from bright surfaces bleed onto nearby walls. Highly realistic environments. Sky Illumination Uses the skybox color to cast natural outdoor lighting. Seamless open-world blending. Infinite Bounces Simulates multiple light reflections across the scene. Deeply immersive interior shadows. Z-Thickness Control
: This version added the ability to use motion vectors, which helps the shader better track pixels between frames, significantly reducing the "ghosting" or flickering typical of earlier screen-space effects .
