An NVIDIA RTX card is not technically required—it works on GTX cards—but an RTX card makes it much more practical.

Enhanced algorithms in 0.36.x allow light to propagate more realistically across surfaces, reducing the "flatness" seen in raw SSRTGI implementations. An NVIDIA RTX card is not technically required—it
Path-Traced Screen-Space Global Illumination (SSGI) in Generic Post-Processing Injectors Author Reference: Based on the work of Pascal Gilcher ( Marty's Mods ) 1. Abstract Abstract Because it only knows what is currently
Because it only knows what is currently on your screen, light from "behind" the camera or behind objects cannot be calculated. This can lead to occasional "flickering" or light disappearing at the edges of the screen. For single-player gaming, RTGI 0.36.1
