Performance and resource costs
After dialing in object thickness, you can adjust the two core lighting parameters:
The shader better distinguishes between indoor environments and open-sky scenarios. In 0.17.0.2, ambient occlusion (the dark shadows in corners and crevices) blends seamlessly with the global illumination, eliminating the "halos" or dark glows that plagued older versions. 4. Precision Depth Buffer Tracking rtgi 0.17.0.2
: RTGI allows light to bounce off surfaces and illuminate areas that are not directly hit by a light source, creating realistic color bleeding.
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 Performance and resource costs After dialing in object
The optimization comes from the early out logic: if a ray hits a surface with low luminance variance, RTGI 0.17.0.2 terminates the ray after 2 bounces instead of the maximum 4. This saves compute without visibly altering the image.
and custom Reshade presets. But the RTGI was the final piece—the "magic" that would turn pixels into light. He launched Precision Depth Buffer Tracking : RTGI allows light
Note: Multiplayer games with anti-cheat software (like Easy Anti-Cheat or BattlEye) often disable the ReShade depth buffer to prevent wall-hacking, which will disable RTGI functionality. Step-by-Step Installation Guide To get RTGI 0.17.0.2 up and running, follow these steps: Step 1: Install ReShade
The architecture of RTGI 0.17.0.2 relies on rendering data extracted directly from the software execution pipeline. Unlike native hardware-accelerated ray tracing (such as NVIDIA RTX or AMD DXR) which utilizes dedicated BVH (Bounding Volume Hierarchy) structures built from true 3D scene geometry, RTGI functions strictly within .
The release of v0.17.0.2 was far from the end of RTGI's development. In fact, the shader has continued to evolve at a breathtaking pace, culminating in what Pascal Gilcher described as "the biggest upgrade yet" in June 2025.
