It shows off a new version of Sonic Ether’s Unbelievable Shaders (SEUS), reports PC Gamer.
Namely, the developers have added support for path tracing, a type of ray tracing. This means that the light from different light sources is reflected and refracted in a more or less natural way. Add a new light source with a different color and the light in the room changes immediately. Open a wall and place a window with slats – suddenly shadows of the slats appear against the walls in the room.
But Minecraft’s game engine isn’t the most efficient, and it shows. Twitter user @notglacier writes that he has a computer with an Intel Core I9-9900k processor and Geforce GTX 1070 Ti, and gets between 25 and 40 frames per second with the shader package activated.
