To make ray tracing playable on mid-range hardware, RTGI reuses lighting data from previous frames (temporal accumulation). In early 0.17 builds, this logic was overly aggressive. Moving characters or vehicles would leave faint trails of light and dark shadows across the screen. 3. Depth Buffer Resets (The Flicker)
The stands as a landmark release for the community. It stabilized path-traced effects for hardware configurations that do not natively support standard developer-implemented ray tracing. Key Fixes in RTGI Version 0.17.0.2
Open the ReShade menu (Home key), find qUINT_RTGI.fx , and enable it. Recommended Settings for Stability: rtgi 01702 release fixed
Certain scenes, particularly those with dynamic weather or heavy skyboxes, caused the global illumination calculations to crash or cause severe screen flickering.
Before dissecting the fix, it is important to understand what aims to accomplish. RTGI stands for Realtime Global Illumination —a rendering technique that simulates how light bounces off surfaces to create indirect lighting, soft shadows, and color bleeding. Unlike screen‑space effects or baked lightmaps, RTGI calculates light paths in real time, dramatically increasing visual fidelity in games and 3D applications. To make ray tracing playable on mid-range hardware,
is a beta version of the popular Ray Traced Global Illumination (RTGI) shader developed by Pascal Gilcher (also known as Marty McFly). This specific release, launched in October 2020, was a critical point in the shader's transition from early testing to a more stable, featured-rich implementation. Overview of RTGI 0.17.0.2
was writing code that shouldn't have worked. He was building , a shader that used a clever trick called "Screen Space Ray Tracing" to simulate light in games that were never built for it. Key Fixes in RTGI Version 0
Run the installer, select your game's primary executable file, and choose the correct rendering API ().
While 0.17.0.2 was a major milestone, it is now considered "horribly outdated" by the community compared to modern iterations like iMMERSE Pro: RTGI . Key Fixes and Improvements
Once the visual artifacts are removed, you can dial in the settings for performance. Consider reducing the if you are encountering VRAM limits. Lowering the bounces while keeping the Ray Length appropriately scaled helps retain the cinematic look of global illumination without dragging your framerate below 60 FPS. The Impact of the Fixes
The many of the hurdles holding back early adopters of ray-traced ReShade. By addressing temporal stability and color accuracy, it enabled a superior visual experience. Even as technology progresses, the 0.17.02 update remains a testament to the rapid improvement of software-based ray tracing.
