While 033 was a stable and beloved version, the RTGI shader has not stood still. Its developer, Pascal Gilcher, is continuously innovating. In a massive update after 033, he attempted to use NVIDIA's advanced ReSTIR GI algorithm but ran into issues like color noise. Undeterred, he , which he claims provides superior quality and stability. Newer versions also feature HiZ (Hierarchical-Z) Min-Max Tracing for pixel-perfect reflections and, most recently, a fully path-traced volumetric fog shader, pushing the boundaries of what's possible with a screen-space injector.
Open your game and press the Home key (or your designated ReShade hotkey) to open the overlay.
: Most games' MSAA will break the depth buffer. Use FXAA or TAA instead. Configure ReShade : Press Home in-game to open the menu.
Performance Tip: Keep this between . Higher values cause massive performance drops in wide-open, outdoor environments. reshade ray tracing shader rtgi 033
While a fantastic tool, RTGI 0.33 is not without its quirks:
Download the latest version of ReShade from the official website.
It is important to understand the limitations of ReShade RTGI v0.33. Unlike native DXR (DirectX Raytracing) or Vulkan Ray Tracing, which have access to the full 3D geometry of the scene, ReShade only sees what is on the screen (the 2D image and depth buffer). While 033 was a stable and beloved version,
On mid-range hardware, such as an Nvidia GTX 1060 or an AMD RX 570, enabling RTGI 0.33 at default or high-quality settings is "very demanding on PC resources," often resulting in severe frame rate drops. Some users have reported that enabling RTGI can reduce performance by 30 frames per second or more in GPU-intensive titles. It is generally recommended for users with high-end cards (RTX 2070 Super or better) for a smooth 60 FPS experience. However, even on high-end rigs, the performance cost can be noticeable; for instance, a preset was noted to cause a massive FPS drop on even a powerful system.
: Higher values provide cleaner lighting but lower FPS.
: Includes options to scale the ray count and step size, allowing users to balance visual fidelity with frame rate. How to Install and Use Undeterred, he , which he claims provides superior
Before diving into the specifics of the 033 version, it's crucial to understand the core technology. The RTGI shader is a post-processing effect designed for ReShade, an open-source tool that allows users to apply custom filters and effects to games. Unlike the standard Ambient Occlusion (SSAO) or simplified Screen-Space Global Illumination (SSGI) found in many games, RTGI employs a form of (or Monte Carlo Integration) to calculate how light rays bounce and interact within a scene, providing a more realistic and physically accurate global illumination effect.

I'll search for relevant sources. search results show various mentions of RTGI 0.33, but no official page. The user likely wants an article covering what RTGI is, its features in version 0.33, installation, usage, performance, and where to get it. I need to gather detailed information from multiple sources. I'll open the relevant results. search results provide a good amount of information about RTGI and its features, but specific details about version 0.33 might be limited. I can structure the article to cover what RTGI is, features of version 0.33, installation, usage, performance, compatibility, community, and where to get it. I'll need to infer some details from the available sources. Now, I'll start writing the article. world of PC gaming is an ever-evolving pursuit of visual perfection, where the line between interactive entertainment and cinematic reality is increasingly blurred. For years, this quest has been centered on Ray Tracing, a rendering technique that simulates realistic light behavior, casting a new level of depth and immersion into virtual worlds. However, for a vast majority of gamers with non-RTX hardware or libraries filled with older titles lacking native support, accessing this technology seemed like a distant dream. This is where the ReShade Ray Tracing Shader RTGI 033 enters the scene, acting as a game-changer. Version 033 of Pascal Gilcher's (also known as Marty McFly) acclaimed Screen-Space Ray Traced Global Illumination (RTGI) shader has become a major milestone for the community. Released around the time of ReShade 5.3.0, this version is celebrated for its refined ability to inject hardware-independent ray-traced global illumination into almost any game, bringing a new level of dynamic lighting to older and modern titles alike.
