Reshade Ray Tracing Shader Rtgi 033 2021 [ 2025-2026 ]

The ReShade RTGI shader is a post-processing effect that simulates . Unlike traditional baked lighting, RTGI facilitates real-time interactive "bounce lighting," where light reflects off surfaces to illuminate areas not directly hit by a primary light source. Key benefits of the 0.33 version include:

The lighting is calculated only based on what is visible on the screen. If a large bright light source is just off-camera, the scene might not reflect that light correctly. Conclusion reshade ray tracing shader rtgi 033 2021

Move your camera fast, and the GI disappears for a frame. If an object goes off screen, its light contribution vanishes instantly (unlike true RT). The ReShade RTGI shader is a post-processing effect

It is important to manage expectations regarding hardware. While this is a "shader," it is computationally expensive. If a large bright light source is just

When you enable the , you gain access to a suite of adjustable parameters. Here is what mattered in 2021:

Here is a comprehensive breakdown of what makes the RTGI 0.33 shader a landmark release, how it works under the hood, and how you can configure it for optimal performance and visual fidelity. The Breakthrough of RTGI 0.33

Racing sim fans used RTGI 0.33 to replace the dull cockpit shadows with realistic light bleed from the track. It made sunset races look photorealistic.
