The RTGI 0.17.0.2 release represents a pivotal moment for enthusiasts of the ReShade RTGI shader. Developed by Pascal Gilcher (also known as Marty McFly), this update was specifically designed to address critical stability and performance issues that players encountered in earlier 0.17.x builds. Understanding the RTGI 0.17.0.2 "Fixed" Update
The RTGI (Ray Traced Global Illumination) shader is a state-of-the-art post-processing tool that physically simulates light interaction within an environment. By utilizing ray tracing techniques, it introduces diffuse global illumination and ambient occlusion to games that do not natively support it.
The 0.17.0.2 release was released in late 2020 as a refined version of the beta, focusing on the following "fixes":
Noise and Dithering Optimization: Earlier versions often suffered from heavy "noise" or graininess. The 0.17.0.2 build improved the denoising algorithm to provide a cleaner image even at lower ray counts.
Depth Buffer Stability: A common issue with RTGI is "flickering" or light bleeding when the game's depth buffer is not correctly aligned. This release included better internal handling for various depth buffer formats.
Legacy Hardware Compatibility: While primarily intended for modern GPUs, this "fixed" version optimized the shader's footprint, making it more viable for users on older NVIDIA or AMD architectures. How to Install and Optimize
For users looking to implement this specific version, the process typically involves the following steps: rtgi 01702 release fixed
Download from Patreon: Official releases, including 0.17.0.2, are traditionally hosted on Pascal Gilcher’s Patreon.
Shader Placement: Extract the contents of the .zip file into your game’s reshade-shaders/Shaders folder.
Depth Buffer Setup: Within the ReShade menu, ensure the depth buffer is active (check the "DisplayDepth" shader to confirm it’s working).
Tuning for Performance: Adjust the "Ray Amount" and "Step Amount" sliders. The 0.17.0.2 version is efficient enough to run at 10–12 rays on most mid-range systems without significant frame drops. Legacy and the NVIDIA Connection
The success of version 0.17.0.2 eventually led to a simplified version of this algorithm being integrated into NVIDIA’s FreeStyle and Ansel drivers as SSRTGI. However, the Patreon version (like 0.17.0.2 and later 0.33 builds) remains the preferred choice for enthusiasts due to its vastly superior customization and experimental feature set.

RTGI version 0.17.2 addresses critical issues, including improved depth buffer detection for DX11/DX12, enhanced UI masking to prevent ghosting, and significantly reduced flickering in high-motion environments. The update also includes optimized spatial filtering and corrected light-leaking bugs, with recommended usage on ReShade 4.8.2 or newer.

Release Notes & Technical Summary – RTGI v0.1702 (Fixed Build)
Version: 0.1702
Release Status: Fixed
Previous Version: 0.1701
Date: [Insert date]
The RTGI shader is a post-processing effect that implements screen-space Ray Traced Global Illumination via compute shaders. It allows for real-time color bleeding, indirect lighting, and ambient occlusion in games that do not natively support Ray Tracing.
The transition from version 0.16 to 0.17 represented a major backend overhaul aimed at increasing compatibility with the latest ReShade versions (5.x+) and fixing long-standing temporal instability.
The fixed version, often labeled RTGI_01702_FIXED or 01702_rev2, addresses every major complaint. Here is the breakdown: Document Title: Release Notes & Technical Summary –
For users who may have reverted to older builds (such as 0.16) due to crashes, the 0.17.02 release is a strong invitation to upgrade back to the latest version. The performance overhead remains consistent with the 0.17 branch, offering better visual fidelity than 0.16 for roughly the same frame cost, provided the crashes have been resolved.
Users are reminded that RTGI remains a Patreon-supported project. As such, access to the 0.17.02 binary requires an active subscription to the developer's Patreon page.
Since the fixed release dropped three days ago, the response has been overwhelmingly positive.
“I was about to give up on RTGI entirely. The old 01702 crashed my 4090 build every 20 minutes. The fixed version ran for a six‑hour session without a single stutter. It’s night and day.” — DigitalDawn, ReShade forum moderator
“The fireflies were making my renders look like a 1990s rave. Now it’s clean enough for production work.” — LightingArtist, Twitter
The only negative comments come from users who downloaded the wrong file (still the original broken release) or who did not purge their old shader cache before installing. A clean installation is mandatory.
