Rtgi 0.17.0.2 -

The shader now includes an automatic quality scaler. If your GPU drops below 45 FPS, RTGI 0.17.0.2 dynamically reduces the number of rays per pixel (RPP) from 6 to 3, then scales up when headroom returns. This feature was experimental in 0.17.0.0 but is now stable and toggleable via RTGI_Performance_Mode.cfg.

The sprawling cityscapes of Los Santos suffer from flat, pre-baked lighting in the vanilla game. RTGI 0.17.0.2 adds incredible bounce lighting inside alleyways and car interiors. The new temporal stability ensures helicopter blades don't turn into a blurry mess.

RTGI 0.17.0.2 is heavy – expect 20–40% FPS drop at 1080p with bounce count=2.

Performance tips:

Look for a section where rays are traced with a fixed step size.

To understand RTGI 0.17.0.2, you need to understand the hardware cost.

Performance delta vs. 0.16.x:

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.

Recommended GPUs:

Note: RTGI 0.17.0.2 still relies on compute shaders, not RT cores. Therefore, Nvidia GTX cards and AMD RX 5000 series run it comparably to low-end RTX cards. rtgi 0.17.0.2

In the ever-evolving landscape of PC gaming modding, few tools have commanded as much respect and attention as Pascal Gilcher’s Ray-Traced Global Illumination (RTGI) shader. Part of the renowned ReShade suite, RTGI has democratized high-end lighting effects, bringing a taste of next-gen illumination to games that were never designed for it.

With the release of RTGI 0.17.0.2, the modding community has been buzzing. This isn't just a minor patch; it represents a significant leap in performance optimization, artifact reduction, and ease of use. Whether you are a seasoned modder or a curious gamer looking to breathe new life into your favorite classic titles, this article breaks down everything you need to know about version 0.17.0.2.
