Min shading rate – Controls the number of rays shot for Antialiasing versus rays for other effects like glossy reflections, GI, area shadows etc. Higher values mean that less time will be spent on Antialiasing, and more effort will be put in the sampling of shading effects.

Example: Anti-aliasing Filters
...
Here is an example briefly demonstrating the effect of different anti-aliasing filters on the final result.
Note that rendering with a particular filter is not the same as rendering without a filter and then blurring the image in a post-processing program like Adobe Photoshop. Filters are applied on a sub-pixel level, over the individual sub-pixel samples. Therefore, applying the filter at render time produces a much more accurate and subtle result than applying it as a post effect. The zoomed in images below have been zoomed in and cropped 300%.
Filter | Image | Zoomed-in Image | Comments | |
Filtering is off. | | | Applies an internal 1x1 pixel box filter. | |
Lanczos filter size 2.0 | ||||
Triangle Filter size 2.5 | ||||
Sinc Filter size 2.5 | ||||
Box Filter size 2.5 | ||||
Area filter size 2.5 | | | Slightly blurs the image, visually more pleasing than the box filter. | |
Catmull-Rom | | | Edge-enhancing filter, often used for architectural visualizations. Note that edge enhancing can produce "moire" effects on detailed geometry. | |
