Installing and using the shader required a few crucial steps, particularly ensuring the shader could "see" the 3D world. reshade ray tracing shader rtgi 033 2021

This version utilized better frame-to-frame data tracking, resulting in stable lighting that did not flicker when the camera moved.

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.

Early versions suffered from a "noisy" or grainy artifact look as rays scattered. 0.33 introduced a smarter spatio-temporal denoiser that smoothed out lighting changes without causing immense motion blur.

ReShade is a generic post-processing injector for games and video software, allowing users to add effects like Bloom, Ambient Occlusion, and Depth of Field. is a premium shader developed by Pascal Gilcher (Marty McFly).

Unlike native hardware ray tracing (like Nvidia RTX or AMD DXR), ReShade RTGI is software-based. It runs on almost any graphics card that supports ReShade, but it is still highly demanding.
