Reshade: Ray Tracing Shader Rtgi 033 2021 _best_

Improved handling of light over time, reducing the flickering ("fireflies") common in earlier versions.

Select your game's .exe and the correct API (usually DX11/12).

RTGI requires access to the game's "Depth Map" to know where objects are.

: Go to the Add-ons (or DX11/DX12) tab in ReShade and try different depth buffer checkboxes until the image appears correctly.

: Version 0.33 introduced the use of motion vectors, which allow the shader to track object movement across frames. This significantly improves temporal stability, reducing the "ghosting" and "shimmering" effects common in earlier versions. Hardware Independence Improved handling of light over time, reducing the

Released in 2021, the 0.33 beta update introduced a highly sophisticated spatial-temporal denoiser. Ray tracing is inherently noisy; it produces a grain effect because tracing infinite rays is impossible in real-time. Version 0.33 solved this by blending lighting data across multiple frames (temporal) and surrounding pixels (spatial), delivering smooth, flicker-free lighting with a fraction of the performance cost of earlier versions. Hardware Requirements and Compatibility

Controls how far light bounces. Keep it low for performance. Ray Amount: Higher values reduce noise but tank FPS.

While Pascal Gilcher has since updated the shader with newer versions (such as RTGI 0.36 and newer beta builds featuring complete path tracing), version 0.33 remains highly regarded. It represents the perfect intersection of stability, highly refined denoising, and modest hardware requirements, cementing its place as a legendary tool in the PC enthusiast's toolkit.

One of the most significant updates in the 0.33 release was the addition of motion vectors, which drastically improved the accuracy of lighting during fast movement. Key Features of Version 0.33 (2021)

Unlike native ray tracing solutions from Nvidia (RTX) or AMD (RX), RTGI 0.33 does not rely on hardware-level BVH (Bounding Volume Hierarchy) traversal. It executes entirely through standard compute shaders. This means you can run ray-traced global illumination on older graphics cards, including the Nvidia GTX 10-series or older AMD Radeon cards.
