[upd] - Reshade Ray Tracing Shader Rtgi 033 2021

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:

One of the biggest hurdles in ray tracing is "noise" (grainy artifacts). 0.33 introduced cleaner filters, making the image look stable even at lower ray counts.

: 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
