and 128 pixels will also show improvement, because the total possible samples can reach 100.

shows a full render with 32 samples and a 0.1 Refinement Shading Rate.
Figure 7-34:
32 Samples/Pixel can be an effective setting with a low Refinement Shading Rate.
Because rendering every pixel in an image multiple times (in this case, 32 times) would take a lot of time
and be a waste in many parts of the image, the Refinement Threshold acts as a contrast check to see where
the antialiasing engine will be engaged. If the brightness of two adjacent pixels falls into the percentage,
the rendering engine calculates only a single pixel. Anything beyond the range is calculated based on the
