Video game graphics have evolved rapidly, but older titles and even some modern releases often lack cutting-edge illumination. Marty McFly’s RTGI (Ray Traced Global Illumination) shader for ReShade completely changes this dynamic. By injecting real-time screen-space ray tracing into almost any 3D game, this shader revolutionizes visual fidelity.
Reduces the "noise" or graininess often seen in ray-traced shadows.

Once you have RTGI working, you'll likely want to fine-tune it for the best balance of visual quality and performance.
If the screen turns completely black or the lighting looks inverted, check the button and change RESHADE_DEPTH_IS_INVERTED from 0 to 1 (or vice versa). Optimizing RTGI 0.33 for Better Performance Video game graphics have evolved rapidly, but older
RTGI is a highly advanced, premium shader designed specifically for ReShade. It simulates how light bounces off surfaces in real time. Unlike standard game lighting, which often relies on pre-baked maps or basic screen-space reflections, RTGI calculates complex lighting paths based on the game's depth buffer. Key Visual Enhancements:
Move the .fx files into the reshade-shaders/Shaders directory. Reduces the "noise" or graininess often seen in
Some users report that enabling RTGI causes ReShade to freeze or display an infinite loading texture. This often relates to depth buffer conflicts or outdated ReShade versions. Solutions include:
A cleaner image with less grainy artifacting in dark corners.
Modifications made to the shader code so it runs smoothly on older ReShade installations, specific game engines, or non-standard graphics APIs (like Vulkan or older DirectX versions).
