Rtgi 0.17.0.2 Release [best] (EXTENDED)

Ray tracing via ReShade is notoriously hardware-intensive because it operates entirely in screen space without internal engine data. The 0.17.0.2 release introduces smarter spatial filtering and code optimization.

Perhaps even more critical was the fix for a long-standing issue: light leaking. Gilcher identified that while the shader was efficient at finding intersections (great for ambient occlusion), it was not pinpoint accurate, leading to light bleeding through solid geometry. The update introduced a "quick and dirty fix" for this problem, ensuring that bounce light no longer incorrectly seeped through occluded areas.

The RTGI 0.17.0.2 release serves as a powerful reminder that high-end graphical effects are not solely the domain of AAA game engines. Through careful optimization and innovative coding, Pascal "Marty McFly" Gilcher continues to push the boundaries of what a post-processing injector can achieve, empowering gamers and creators to experience ray-traced global illumination without the need for dedicated high-end hardware. The shader's evolution from the 0.17.0.2 optimization baseline to the algorithm-shattering 2025 releases demonstrates the incredible progress possible when passionate developers refine their tools over time. It establishes a benchmark for community-driven graphics, ensuring that the visual quality of PC games will continue to soar, driven by the ingenuity of modders for years to come.

The engine casts a relatively low number of rays from each probe into the scene. These rays hit geometry, sample the material properties, and calculate the incoming light.

The first major enhancement involved how the shader captured tiny geometric features. As shown in initial comparisons, small surface details—such as the step of a pillar—would often fail to cast sufficient bounce light onto adjacent walls. The new ray intersector in RTGI 0.17.0.2 was meticulously reworked to catch these small details effortlessly, resulting in significantly more accurate and "solid" lighting for fine surface geometry.

Overview

To use this specific version, you generally need the following:

The developer has streamlined the underlying code to better utilize the architectural strengths of modern graphics cards, including NVIDIA’s RTX series, AMD’s RX line, and Intel Arc GPUs. Compute shader dispatches are tighter, leading to improved frame pacing and fewer micro-stutters during rapid camera movements. Performance Impact: What to Expect
