Critically, RTGI operates on depth data alone. This hardware independence means it is fully compatible with non-RTX video cards and has no inherent hardware feature requirements, though ray tracing is fundamentally demanding. It uses innovative methods to accelerate ray marching, often outperforming hardware-accelerated ray tracing on meshes reconstructed from depth input. However, due to its screen-space nature, it can only directly observe surfaces currently facing the camera, which sometimes requires workarounds or adjustments.
The "Dreamers RTGI" mod for the Tomb Raider series provides a simple installation process: extract the preset into the game's main folder, install ReShade with DirectX 10/11/12 support, and the effect is ready to go. While the documentation does not specify the exact RTGI version, the mod's release date (June 2022) makes it compatible with the v0.17.0.2 lineage.
Runs on almost any GPU geometry—including legacy architectures—since it does not rely on dedicated ray-tracing hardware blocks. The Core Technical Workflow of 0.17.0.2 rtgi 0.17.0.2
RTGI 0.17.0.2 has far-reaching implications across various industries:
The shader reconstructs a 3D scene representation from the 2D depth map. Critically, RTGI operates on depth data alone
It paved the way for subsequent updates and influenced the development of technologies like NVIDIA’s own SSRTGI (Screen-Space Ray Traced Global Illumination) seen in modern games. *If you'd like, I can: for 0.17.0.2. Compare its visuals to newer versions. Recommend specific settings for games like GTA V.*
As a screen-space, software-based solution, RTGI's performance scales with screen resolution and the complexity of the scene. Ray tracing is inherently demanding. Users report a frame rate impact ranging from or more, depending on the quality settings and the hardware involved. However, the optimizations introduced in version 0.17.0.2 were specifically designed to mitigate this impact. However, due to its screen-space nature, it can
Ray tracing inherently introduces visual noise or "graininess" due to limited ray counts. This version features an overhauled denoiser that combines spatial data (pixels next to each other) and temporal data (frames over time). The result is a clean, stable image with minimal ghosting or trailing artifacts during fast camera movements. Enhanced Screen-Space Depth Assessment
Extract the contents, specifically the shader and texture folders, into the reshade-shaders folder within your game's directory.
RTGI stands for . It operates as a post-processing plugin injected directly into a game's rendering pipeline using the ReShade universal shader injector.
