The shader now includes an . If your GPU drops below 45 FPS, RTGI 0.17.0.2 dynamically reduces the number of rays per pixel (RPP) from 6 to 3, then scales up when headroom returns. This feature was experimental in 0.17.0.0 but is now stable and toggleable via RTGI_Performance_Mode.cfg .
The algorithm now better differentiates between "new light information" and "temporal noise." Users will notice that static scenes look plastic-smooth, while moving objects retain a natural grain without the dancing pixels of older iterations. rtgi 0.17.0.2
