Raytracing Engine Options
This zone permits the CPU resources to be allocated to the raytracing engine to be defined. Three options are available: Use all CPU cores, Use all CPU cores but one, and Manual thread count.
The Tile size in pixels can also be set. During the calculation of a rendering via raytracing, the image is rendered and displayed tile by tile in the viewport. The smaller the blocks are, the more fluid the display will be, but the rendering time will also be longer. The height and width of these square tiles corresponds to the number of pixels provided in this field.
