What does "22-62 Smoothened" Mean?

[hawkhill]

When I checked the options for Frame-Rate Cap., I would see a range from 20 to unlimited. But one particular one confused me. The "Smoothened 22-62" option.
Why so specific? What does it mean by Smoothened, exactly? And what makes it so different from 60 Capped option, other than being 2 frames extra? Please explain. Thank you!

In a more technical explanation (found here: https://answers.unrealengine.com/questions/90743/what-exactly-does-smooth-frame-rate-do.html):
"With Frame Rate Smoothing, the application is determining what range is acceptable for frame rate wandering, so you can cap your frame rate to between Min and Max allowable frame rates. Since this is application based, it will make these changes before any hardware vsync changes."

Basically, 22 and 60 are MIN and MAX frame rates allowed with this option, which also gives a smooth variation (more "fluid" animations in-game, but I don't know how to describe this with right words). This option is recommended if you have a low end PC.
