Reshade Ray Tracing Shader Rtgi 033 2021 Jun 2026

RTGI stands for Ray Traced Global Illumination. It is a post-processing shader created for the ReShade framework. Unlike native hardware ray tracing built into game engines, RTGI works externally. It utilizes the game’s depth buffer to calculate how light bounces off objects within the player's field of view. The 2021 Breakthrough: Version 0.33

High temporal denoising values can cause a trailing effect behind moving objects.

The functions by intercepting the game's depth buffer (the data map showing how close or far geometry is from the camera). It casts thousands of virtual light rays across this screen-space data to accurately compute Diffuse Global Illumination and ambient contact shadows in real-time. Key Milestones in the 2021 Era reshade ray tracing shader rtgi 033 2021

Real-world light bounces infinitely. RTGI 0.33 refined the approximation of secondary and tertiary light bounces. When a ray hits a bright red surface, it accurately carries that red tint onto neighboring white walls. This creates a realistic color bleeding effect that traditional ambient occlusion methods cannot replicate. How Screen-Space Ray Tracing Works

Launch the game and open the ReShade overlay (usually the key). Navigate to the Add-ons tab. RTGI stands for Ray Traced Global Illumination

: Reduce the temporal blending factor in the shader settings or increase your base in-game framerate. To get the most out of your setup, let me know: Which game you are trying to mod? What graphics card do you have? Are you currently getting any error messages in ReShade?

Here is a blog post you can use to break down how it works and why it’s a game-changer. It utilizes the game’s depth buffer to calculate

Note regarding "Piece": If you are asking for a "piece" of code or a specific download link, I cannot provide direct download links for paid/patron software. However, v0.33 was widely circulated as a "public test" build at the time.

: Light takes on the color of the surfaces it reflects from, creating realistic ambient lighting.
