Rtgi 0.17.0.2

However, a note of caution: RTGI is not a miracle worker. Because it is a post-process effect (it only sees the 2D final image and the depth buffer), it cannot handle data that isn't on the screen. If a light source is behind the camera, RTGI cannot bounce it. For that, you need native engine raytracing (like Cyberpunk 2077's Psycho mode).

Ensure your game is running in 4K for the best results, as screen-space techniques depend on screen resolution. 2. Basic Configuration (Within ReShade Menu) Enable RTGI: qUINT_RTGI.fx in the ReShade menu and activate it. Depth Buffer Issues: If the image is upside down, adjust the Global Preprocessor Definitions under the "Home" tab to fix the RESHADE_DEPTH_INPUT_IS_UPSIDE_DOWN setting (toggle from 0 to 1 or 1 to 0). Performance:

, was designed to bring screen-space ray tracing effects to older or non-RTX titles like Grand Theft Auto V Alien: Isolation Key Details & Access Developer: Pascal Gilcher (Marty McFly). Official Source: The shader is distributed exclusively through Pascal Gilcher's Patreon

Extract the contents, specifically the shader and texture folders, into the reshade-shaders folder within your game's directory. rtgi 0.17.0.2

If your character stands next to a neon blue sign, their clothes and the surrounding concrete will realistically catch a blue tint.

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

Integration and engineering considerations However, a note of caution: RTGI is not a miracle worker

Users can improve performance by adjusting settings within the RTGI menu, such as reducing the number of rays (sampling) or lowering the resolution of the GI effect.

→ depth buffer wrong (invert / format) Too noisy → reduce Ray Length or Intensity, or accept as stylistic Too dark → increase Intensity / Bounce Count Too slow → Bounce Count = 1, lower Ray Length Artifacts on edges → screen-space limitation – unavoidable

Let’s break down what specifically changed from 0.17.0.1 to 0.17.0.2. For that, you need native engine raytracing (like

If you want, I can:

RTGI 0.17.0.2 is computationally heavy because it processes complex mathematical equations on the GPU in real-time.

: If the shading moves inversely to your camera, toggle the global preprocessor definition RESHADE_DEPTH_INPUT_IS_REVERSED between 0 and 1 .

⚠️ Do use with older ReShade 4.x – missing math functions.
