Reshade Ray Tracing Shader Rtgi 0.33 -
Let’s be real: RTGI costs FPS. On an RTX 3060 at 1440p:
But here’s the magic — because it’s screen-space, it scales with resolution and scene complexity, not polygon count. A game like Skyrim with heavy mods hits harder than Dishonored 2 with simple geometry.
Pro tip: Turn down ReShade’s “Effect Resolution” to 0.5x. You’ll barely see the difference in motion, but you’ll gain back 10–15% FPS.
The most exciting feature for power users in 0.33 is the Multi-Pass capability. You can now run two instances of RTGI in a single preset:
When blended together, the result looks indistinguishable from native engine Ray Tracing, but running on hardware that is five years old.
One of the biggest headaches with ReShade is getting the mod to understand what is a wall versus what is the sky. Version 0.33 includes smarter automatic depth buffer detection for DirectX 9, 10, 11, and 12 titles. Fewer crashes, fewer pink screens.
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.

Title: Illuminating the Shadows: An Informative Review of ReShade Ray Tracing Shader RTGI 0.33
Introduction For years, PC gamers have sought ways to bridge the gap between traditional rasterization and modern hardware-accelerated ray tracing. While Nvidia’s RTX and AMD’s Radeon Rays have pushed the industry forward, not every game supports these features, and performance costs can be steep. Enter Pascal Gilcher’s RTGI (Ray Traced Global Illumination) shader for ReShade. Specifically, version 0.33 represents a significant milestone in the accessibility of software-based ray tracing. This review examines the technical capabilities, visual impact, and performance implications of RTGI 0.33.
What is RTGI? RTGI is a post-processing shader that simulates Global Illumination (GI) in real-time. Unlike native ray tracing implemented in a game engine (which traces rays during the geometry rendering phase), RTGI works with the final image (color, depth, and normals) generated by the game. It calculates how light bounces off surfaces and into shadowed areas, effectively eliminating the "flat" look of games that rely solely on static lighting or simple dynamic shadows.
Key Features of Version 0.33 Version 0.33 is not just a minor update; it refines the core architecture of the shader significantly.
Visual Impact: The "Wow" Factor The primary selling point of RTGI is the dramatic shift in atmosphere.
Performance Analysis It is crucial to manage expectations regarding performance. RTGI is computationally expensive because it runs on the GPU's generic compute shaders, rather than dedicated RT cores.
Limitations and Drawbacks While impressive, RTGI 0.33 is not magic; it has inherent limitations due to being a screen-space effect.
Verdict RTGI 0.33 is arguably the single most transformative shader available in the ReShade ecosystem. It takes games that look dated or "flat" and injects them with a modern, high-fidelity lighting engine.
While it is not a replacement for native hardware ray tracing—due to screen-space limitations and a heavy performance tax—it serves as an incredible tool for breathing new life into older titles or enhancing games that lack advanced lighting.
For gamers with headroom on their GPU who prioritize visual immersion over raw framerates, RTGI 0.33 is an essential addition to the modding toolkit. It proves that lighting is the foundation of visual realism, and with this shader, that foundation is stronger than ever.
Score: 9/10 (Deducted points strictly for the high performance cost and UI setup requirements).
The ReShade RTGI (Ray Traced Global Illumination) shader, developed by Pascal Gilcher (also known as Marty McFly
), is a post-processing tool that adds dynamic, realistic lighting and ambient occlusion to games by utilizing depth data. Version
, released around August 2022, was a significant update that introduced motion vectors to improve temporal stability and performance. Key Features of RTGI 0.33 Motion Vector Support : Requires the additional MotionVectors.fx
shader to help RTGI track pixel movement, significantly reducing flickering and ghosting while reclaiming some FPS. Hardware Independence
: Unlike native RTX, this shader works on most modern GPUs (including non-RTX cards) because it operates on the game's depth buffer rather than specialized hardware. Diffuse & Specular GI
: Models how light realistically bounces off surfaces to illuminate shadows and add subtle color bleeding from the environment. Depth-Based Ray Tracing
: Uses the screen's depth information to calculate light occlusion, providing a much higher level of detail than standard screen-space ambient occlusion (SSAO). Installation & Setup Requirements Let’s be real: RTGI costs FPS
To use RTGI 0.33 effectively, you typically need the following: ReShade with Full Add-on Support
: Essential for many games to allow the depth buffer to remain active during network activity or to access advanced features. Depth Buffer Access
: The game's depth buffer must be correctly configured in the ReShade "Edit global processor definitions" or the "Add-ons" tab. If the depth buffer is "reversed" or "logarithmic," RTGI will not display correctly. Companion Shaders : Specifically MotionVectors.fx , which can be found on Marty McFly's GitHub Vulkan/DX11/DX12
: While RTGI supports various APIs, newer versions (including 0.33) have dropped official DX9 support; a Vulkan wrapper is recommended for older DX9 titles.
The phrase “Reshade Ray Tracing shader RTGI 0.33” refers to a specific, older version of a popular screen-space ray tracing effect for ReShade.
Here’s a breakdown of what each part means:
Important notes about this specific version (0.33):
If you have a file named like that (e.g., RTGI.fx with version 0.33), you can use it with ReShade 4.9.1 or older. Newer ReShade versions (5.0+) may have compatibility issues with that old shader code.
Would you like help installing and configuring RTGI 0.33, or are you looking for the newer version instead?
The ReShade RTGI 0.33 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.
Below is an in-depth breakdown of the ReShade RTGI 0.33 shader, its core enhancements, and how to configure it. 💡 What is ReShade RTGI 0.33?
The acronym RTGI 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.
The 0.33 update introduced critical performance and fidelity enhancements, most notably integration with advanced motion estimation vectors via auxiliary shaders. 🚀 Key Features in Version 0.33 1. Motion Vectors & Temporal Stability
In version 0.33, the RTGI shader pairs with the Launchpad shader, 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
RTGI 0.33 provides more accurate diffuse global illumination. 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 0.33 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
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
I’ve written this for a typical PC gaming/graphics enthusiast blog — informative, slightly technical, but not overly academic.
Marty McFly has since moved on to RTGI 0.50+ (currently in Patreon beta) which uses "ReSTIR GI" — similar to what NVIDIA uses in its developer SDKs. Furthermore, Reshade 6.0 now includes a native "Depth3D+" system that conflicts with older RTGI builds. But here’s the magic — because it’s screen-space
Does that kill RTGI 0.33? No. In the modding community, stability beats features. Because 0.33 is "finished" (no more updates), it will never break your game due to a Reshade update. It is the archival gold standard. For games built on the Creation Engine (Skyrim, Fallout 4) or Unreal Engine 3 (BioShock, Arkham Asylum), 0.33 remains the easiest, most crash-free path to ray traced illumination.
