RTGI 0.17.0.2 remains a foundational version for post-processing ray tracing. While it requires precise folder structure and depth buffer access, it provides a high-fidelity lighting solution for legacy and modern titles lacking native RTX support.
| Issue | Description | How the RTGI 01702 Update Fixed It | | :--- | :--- | :--- | | | A well-known problem in older DirectX 9 titles where enabling RTGI would result in large, corrupting black bars across the screen. | While the developer introduced fixes, the community often combined RTGI 0.17.0.2 with workarounds like the DXVK translation layer (converting DX9 to Vulkan) to ensure a stable, bug-free experience. | | Excessive Performance Overhead | Previous versions required a high sample count to produce a clean image, leading to a large performance penalty. | The update's "less samples with same look" approach directly addressed this. The rewritten sampling and culling prepass meant the shader could now achieve a clean look with far less computational expense. | | Infinite Loading Texture in ReShade | In some games, enabling RTGI would cause the ReShade overlay to freeze or show a loading texture indefinitely, breaking the effect. | By stabilizing the shader's core loops and memory management, 0.17.0.2 reduced the likelihood of these crashes and freezes, making it the recommended version for users experiencing instability. | | "Bright Shadows" and Light Leaking | Early RTGI implementations often produced unnaturally bright shadows or light leaking through solid objects, breaking immersion. | The refined sampling logic and better integration with the depth buffer in 0.17.0.2 provided more accurate shadowing and indirect lighting, significantly reducing these artifacts. |
Hardware anti-aliasing can split the depth target into multiple samples, rendering it unreadable to ReShade. Use SMAA or FXAA inside ReShade instead.
Higher values allow light to bounce further but increase noise. 3 or 4 Determines ray count. Keeping this low saves massive FPS. Steps Amount 8 to 12
Visit the official ReShade website and download the latest version (ideally the version, which is required for depth-buffer access in multiplayer-disabled games). Run the installer and select your game's executable. Choose "Update" when prompted.
Many community-driven fixes require a quick edit to the qquint_rtgi.fx file to solve the compilation loop and normal map glitches. Navigate to your game's installation directory. Open the reshade-shaders\Shaders folder.
Toggle RESHADE_DEPTH_IS_REVERSED between 0 and 1 until you see the lighting align with the objects on your screen. If objects cast light in front of themselves instead of behind, change this setting. Optimizing Performance Post-Fix
For games that require depth buffer manipulation to make RTGI work correctly, always use the ReShade build that includes full add-on support.
This active development cycle means that most "01702" style problems are fixed quickly by the developer. Users are strongly encouraged to check the official Patreon feed or the ReShade forum threads (specifically Pascal Gilcher's section) for dedicated hotfixes, as the developer is known for rapid iteration when visual bugs are discovered.
