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.
Adds dramatic shadows under vehicles and realistic sun rays bouncing off tarmac and building facades.
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.
This build is a GPU heavy-hitter. Try lowering the "Ray Length" or "Amount" if your frames are tanking. 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.
Standard video game lighting often relies on static lightmaps or basic ambient occlusion (like SSAO). These methods frequently leave scenes looking flat, disconnected, or unnaturally glowing. RTGI 0.17.0.2 fundamentally transforms scenes by introducing two critical lighting behaviors: 1. True Color Bleeding However, the optimizations introduced in version 0
| Setting | Recommended start value | Note | |--------|----------------------|------| | | 0.20–0.35 | Larger = farther bounce but more artifacts | | Bounce Count | 2 | 1 for performance, 3+ for quality | | Intensity | 0.6–1.0 | Bounce light brightness | | AO Strength | 0.4 | Ambient occlusion contribution | | Enable specular | On | If game has rough/metal materials | | Temporal accumulation | Off | Not stable in 0.17 – causes ghosting |
With the release of version , this screen-space ray tracing shader reaches a new peak of optimization, compatibility, and visual fidelity. Whether you are revisiting classic RPGs, enhancing competitive shooters, or pushing your graphics card to its absolute limits, RTGI 0.17.0.2 injects modern lighting into older engines.
It does not require an RTX-capable graphics card. It runs on any card capable of running ReShade, making it highly accessible. This hardware independence means it is fully compatible
Real-time ray tracing through ReShade requires access to the depth buffer. Anti-aliasing (like MSAA) often hides this buffer. Disable in-game AA for the best results.
It focuses on real-time global illumination, adding depth and realistic lighting bounces to games by using the game's depth buffer. Common Usage & Troubleshooting Visual Enhancements:
