, which significantly improves the temporal stability of the lighting effect during movement. Screen-Space Ray Tracing
Once RTGI is enabled, open the shader parameters menu at the bottom of the ReShade overlay to fine-tune the look. Ray Length & Ray Quality
RTGI solves this by calculating how light bounces around a scene in real-time. It simulates how light behaves in the real world: colors bleed onto nearby surfaces (color bleeding), shadows become softer and more realistic the further they get from the object (contact hardening shadows), and ambient light feels natural rather than flat. reshade ray tracing shader rtgi 033
As the field of real-time ray tracing continues to evolve, we can expect to see even more innovative applications of this technology. Some potential areas of development include:
Once this reconstruction is built, RTGI 0.33 performs a "path tracing" simulation on this screen-space data. Because it has no access to geometry outside your current field of view, RTGI must make intelligent estimates for occluded areas and surfaces that are hidden from the camera. While this approach has limitations, Gilcher's algorithm used a proprietary method distinct from the earlier, more popular ReSTIR GI technique, aiming to maintain high visual fidelity even while relying on limited data. By version 0.33, the technology had proven itself capable of generating temporally stable lighting, minimizing the distracting flickering that often plagued other screen-space solutions.
The world of computer graphics is constantly evolving, with developers and enthusiasts alike pushing the boundaries of what is possible. One of the most exciting advancements in recent years is the integration of ray tracing technology into graphics processing. ReShade, a popular post-processing injector, has taken this to the next level with its Ray Tracing Shader RTGI 0.3.3. In this write-up, we'll explore the capabilities of this innovative shader and what it means for the future of graphics rendering. This public link is valid for 7 days
Furthermore, because RTGI modifies visual data after the game has rendered its own effects, users may experience on UI elements or during loading screens. Transparent UI panels might become translucent, or HUD elements may cast fake shadows as the shader mistakenly interprets them as 3D geometry. The developer recommends turning off the game's built-in anti-aliasing (AA) and SSAO (Screen Space Ambient Occlusion) before using RTGI to prevent conflicts and ensure the depth buffer reads are clean. Failure to disable in-game AA is one of the most common reasons for RTGI failing to render correctly.
Go back to the tab and enable the DisplayDepth shader to verify. Your screen should split into a clear gray depth map and a normal map. If it is blank, toggle the global preprocessor definitions like RESHADE_DEPTH_IS_INVERTED between 0 and 1 . Master Setting Explanations for RTGI 0.33
: Users frequently note that RTGI 0.33 significantly improves ambient occlusion and indirect lighting . It fills in shadows in areas where traditional screen-space effects (SSAO) fail, making environments feel more grounded and "physical". Can’t copy the link right now

Finally got my hands on the new RTGI 0.33 update for ReShade. 🤯
: Simulates complex light paths where light hits a surface, picks up its color, and bounces onto another.
RTGI v0.33 isn’t the future of real-time rendering—it’s a clever hack from a brilliant modder (Marty McFly) who refused to wait for game devs to catch up. In the right game, on the right hardware, it feels like magic. In the wrong game, it’s a performance-killing noise machine.
