Reshade Ray Tracing Shader Rtgi 033 2021

In 2021, the ReShade RTGI (Ray Traced Global Illumination) shader, developed by Pascal Gilcher (Marty McFly), was a transformative post-processing tool that brought advanced lighting effects to games without native ray tracing support. Version

Cons:

For gamers, it opens up the possibility of experiencing ray tracing in games that originally lacked it. For developers, it serves as a bridge to more advanced rendering techniques without the need for extensive game engine overhauls. reshade ray tracing shader rtgi 033 2021

Ray Length:

Controls how far light bounces. Keep it low for performance. Ray Amount: Higher values reduce noise but tank FPS. In 2021, the ReShade RTGI (Ray Traced Global

• RTGI 0.33 (2021): Stable, great performance, best for lighting bounce.
• IL (Illumination) 2023: Better reflections, but heavier performance.
• SSR (Screen Space Reflections): Better for mirrors, worse for lighting.

March 2021

– While NVIDIA and AMD pushed hardware-accelerated ray tracing in blockbusters like Cyberpunk 2077 and Control , PC gamers with older GPUs or libraries of classic titles were largely left in the dark. Enter Pascal “Marty McFly” Gilcher and version 0.33 of RTGI (ReShade Ray Tracing Global Illumination) – a shader that simulated ray-traced global illumination using only post-processing, no specialized RT cores required.
