While ReSTIR GI is incredibly powerful, Gilcher was highly critical of the technique, citing chromatic noise, difficulty in variance estimation, and unstable white noise as its primary shortcomings. In the years following the 0.17.0.2 release, Gilcher even claimed that his own RTGI shader outperformed ReSTIR GI in visual quality and stability for screen-space applications. Where ReSTIR relies on reservoir resampling from sample streams, RTGI focused on brute-force, pixel-accurate path tracing within the screen-space, producing temporally stable lighting without the flickering often seen in other solutions.
