Is there any scenario that can visually demonstrate the role of Subpixel Mapping and Max Ray Latency?

Like the options in the picture, is there a scene that can demonstrate their function

It’s quite easy, maximum ray intensity will cut out the amount of “energy” of the ray, perform a couple tests with a low and a high setting and it will be very noticeable. It may help reducing high energy pixels in the scene that can cause several artifacts. Subpixel mapping oversamples areas of the scene where you have very bright pixels next to darker pixels. The antialiasing sampler can not resolve those areas efficiently and it will give you a sharp transition, the subpixel mapping will smooth out this transition. It was useful a long time ago but today those imperfections are easily manageable by adding a bit of lens effects that will hide the sharp transition and look more natural.

Thank you for your explanation
