Rtgi 0.17.0.2 Release [2021]

The 2–5% uplift on NVIDIA Turing+ is real but subtle. More importantly, is improved. The old stutter when temporal accumulation resets (e.g., after a loading screen or cutscene) is almost gone. On AMD, the crash fix for depth buffer toggling is a lifesaver—no more CTDs when alt-tabbing.

: Adds real-time light bounces to game environments, making colors and shadows feel more physically accurate. Hardware Independence : Unlike native RTX implementations, RTGI works on non-RTX hardware rtgi 0.17.0.2 release

The principles established in 0.17.0.2 set the stage for future breakthroughs. While 0.17.0.2 optimized existing code, later updates in 2025 introduced entirely new algorithms. In June 2025, after a six-month hiatus, Pascal Gilcher unveiled what he called the "biggest upgrade yet" for RTGI. This update achieved a significant advance in ray tracing technology: its author claims it vastly outperforms Nvidia's ReSTIR GI in quality terms. ReSTIR GI represents the "state of the art for Global Illumination effects", but Gilcher developed a proprietary sampling algorithm that avoids many of its drawbacks, such as chroma noise and broken denoiser variance estimation.

Always leave this checked. The 0.17.0.2 optimization ensures that the visual leap of multi-bounce light is well worth the negligible performance hit. Final Verdict The 2–5% uplift on NVIDIA Turing+ is real but subtle

Software-based ray tracing strains the GPU. The developer rewritten core parts of the underlying code to utilize modern GPU architectures more efficiently. Users report a 10% to 15% frame rate improvement compared to the early 0.16 builds, making 60 FPS gameplay much more achievable on mid-range graphics cards. Performance Impact: What to Expect

Community discussion surrounding the version notes improvements in image stability. As the official RTGI documentation explains, the shader produces "very temporally stable lighting, minimizing flickering or temporal lag commonly seen in other solutions". Users who upgraded experienced a more performant application without the frustration of re-tuning their visual setups, with the shader remaining accurate in its modeling of both "diffuse and specular Global Illumination".

The RTGI (Ray Traced Global Illumination) 0.17.0.2 release, authored by (also known as Marty McFly), was a pivotal beta update for the popular ReShade shader that brings software-based ray tracing to virtually any DX9, DX11, or DX12 game. Key Features of RTGI 0.17.0.2
