Reshade Ray Tracing - Shader Rtgi 033 Exclusive
| Problem | Likely Cause | Solution |
|---------|--------------|----------|
| Black screen or no GI | Wrong ReShade version | Use 4.9.1, not 5.x |
| Flickering/boiling light | Screen-space + no denoiser | Increase ray length, lower intensity, or accept as style |
| GI only near screen center | Screen-space artifact | Turn camera or accept limitation |
| Crashes on launch | Depth buffer access | Enable Copy depth buffer before clear in ReShade settings |
| Objects glow incorrectly | Incorrect depth buffer | Use DisplayDepth shader to debug; adjust Depth Buffer in ReShade add-ons |
You are likely looking at a filename or a download title for Pascal Gilcher's RTGI Shader (Version 0.33).

Safety Warning: If you are downloading a file with this name from a random website (not the official ReShade repository, the developer's Patreon, or a reputable site like Nexus Mods), be careful, as shader files can sometimes be wrapped in malware by third parties.
The ReShade RTGI 0.33 shader, created by Pascal Gilcher (also known as Marty McFly), is a highly advanced screen-space ray tracing tool that adds dynamic global illumination (GI) and ambient occlusion (AO) to almost any 3D game. While RTGI has since moved to newer versions like 0.70, version 0.33 remains a landmark release for its specific feature set and widespread adoption in various mod presets. Core Features of RTGI 0.33 reshade ray tracing shader rtgi 033 exclusive
Ray Traced Global Illumination (RTGI): Physically simulates how light bounces off surfaces, allowing colors from the floor or walls to bleed into the surrounding environment and illuminate dark corners.
Motion Vectors Support: One of the most critical additions in version 0.33 was support for motion vectors. This allows the shader to track object movement between frames, significantly reducing "ghosting" artifacts and improving temporal stability.
Hardware Independence: Unlike official "RTX" ray tracing, this shader does not require specialized RT cores. It runs on most DirectX 9, 11, 12, and Vulkan-compatible hardware by using the game's depth buffer data.
Depth-Based Lighting: It uses screen-space information to determine where shadows (Ambient Occlusion) and light bounces (Global Illumination) should occur, making it compatible with older titles that never had modern lighting engines. Performance & Requirements | Problem | Likely Cause | Solution |
However, note: As of my current knowledge cutoff in October 2023, the latest public version of RTGI was around 0.32 or earlier 0.33 beta. If "0.33 exclusive" refers to a newer Patreon-exclusive or beta release after that date, I recommend checking Pascal Gilcher's Patreon or GitHub for the most up-to-date changelog.
Below is a feature overview / highlight sheet based on what a typical "exclusive 0.33" update would likely include, following the pattern of previous RTGI updates (0.30 → 0.31 → 0.32):
Pascal Gilcher has moved on to RTGI "Mortens" (version 2.0), which uses Machine Learning (ML) denoising. It is incredible, but it requires an NVIDIA RTX 2060 or better to run at 1440p.
That means RTGI 0.33 Exclusive remains the ultimate democratization tool. It allows: You are likely looking at a filename or
The "exclusive" nature of 0.33—paywalled for a year and then abandoned—has ironically preserved it. Because it is no longer updated, it is stable. It is a time capsule of the perfect balance between visual fidelity and computational cost.
If you meant a different version (e.g., 0.33 is actually a typo for 0.32 or 0.34), or you want me to write a YouTube video script, Reddit post, review, or tutorial about it, just let me know!
Always ensure "Write to Normals Buffer" is checked in the bottom of the RTGI panel. Without this, light will ignore the angle of surfaces, making everything look flat like a 90s game.
