: Unlike "true" hardware-based ray tracing, this shader operates on depth buffer information . This means it can only "trace" what is currently visible on your screen, acting as a highly advanced form of ambient occlusion.
One of the most significant challenges in implementing real-time ray tracing is maintaining performance. The ReShade Ray Tracing Shader RTGI 0.3.3 has been carefully optimized to minimize computational overhead, ensuring smooth, consistent performance across a wide range of hardware configurations. reshade ray tracing shader rtgi 033
RTGI requires depth data to "see" where objects are in 3D space. : Unlike "true" hardware-based ray tracing, this shader
