The algorithm now better differentiates between "new light information" and "temporal noise." Users will notice that static scenes look plastic-smooth, while moving objects retain a natural grain without the dancing pixels of older iterations. Ray tracing is notoriously expensive. However, RTGI 0.17.0.2 includes a new Adaptive Ray Count . Instead of casting the same number of rays across the entire screen, the shader intelligently reduces ray counts in darker, shadowed areas where high precision is unnecessary, and focuses compute power on brightly lit surfaces.
| Issue | Solution | | :--- | :--- | | | This is a depth buffer access error. Go to ReShade settings ( Home -> Add-ons ). Find "Copy Depth Buffer Before Clear Operations." Toggle it ON. | | Character outlines have a glowing aura | Your "Depth Rejection" is too low. Navigate to the RTGI variables. Increase Rejection Threshold from 0.5 to 0.8 or 0.9. | | Massive FPS drop (50% loss) | You likely have "Trace Quality" set to "Ultra." Drop it to "Balanced." In 0.17.0.2, the visual difference is minimal, but the performance gap is large. | | No lighting change at all | Ensure your game's native Ambient Occlusion (SSAO/HBAO) is turned OFF in the game’s video settings.

With the release of , the modding community has been buzzing. This isn't just a minor patch; it represents a significant leap in performance optimization, artifact reduction, and ease of use. Whether you are a seasoned modder or a curious gamer looking to breathe new life into your favorite classic titles, this article breaks down everything you need to know about version 0.17.0.2. What is RTGI? A Brief Refresher Before diving into the specifics of version 0.17.0.2, let’s establish the baseline. RTGI (Ray-Traced Global Illumination) is a proprietary ReShade filter that simulates how light bounces off surfaces. Unlike screen-space ambient occlusion (SSAO), which only darkens creases, RTGI calculates the color bleed and indirect lighting that occurs when light hits a colored wall, a character’s skin, or a grassy field. The algorithm now better differentiates between "new light
Early benchmarks suggest a 15-20% performance gain over version 0.16 on the same hardware (tested on an RTX 3060 and RX 6700 XT). A persistent issue with post-process ray tracing is "haloing"—where an object in the foreground bleeds light information from the background. Version 0.17.0.2 implements a stricter depth rejection parameter . This reduces the "ghosting" effect behind moving characters substantially, though it may require slight tweaking per game. Installation Guide: Getting RTGI 0.17.0.2 Running Because RTGI is a paid shader (available via Patreon), the installation process differs from standard free ReShade effects. Instead of casting the same number of rays
In the ever-evolving landscape of PC gaming modding, few tools have commanded as much respect and attention as Pascal Gilcher’s Ray-Traced Global Illumination (RTGI) shader. Part of the renowned ReShade suite, RTGI has democratized high-end lighting effects, bringing a taste of next-gen illumination to games that were never designed for it.
However, a note of caution: RTGI is not a miracle worker. Because it is a post-process effect (it only sees the 2D final image and the depth buffer), it cannot handle data that isn't on the screen. If a light source is behind the camera, RTGI cannot bounce it. For that, you need native engine raytracing (like Cyberpunk 2077's Psycho mode).
Furthermore, the improved efficiency hints that future RTGI versions might run on integrated graphics (like the Steam Deck) at playable frame rates—something unthinkable just two years ago. RTGI 0.17.0.2 is not a revolution; it is an evolution. It fixes the annoying flickering of its predecessors, runs faster on mid-range hardware, and finally makes post-process ray tracing viable for fast-paced action games.
