View New Content - Sphinx

[RevengeFNF]

I have a question:

In my board i get more or less a new post every 5 minutes. In busy times, like when there are a football match or a discussion in a topic it can reach several post per minute.

It secure to use the View New Content with Sphinx and update the Delta every minute.

In 3.4.x this is possible to do. In IPS4 i don't see any option to do it. What happens if i choose Sphinx? View New Content will still use SQL?

 

PS: In my board, the View New Content takes half the time to load with Sphinx. Which is awesome.

So, someone can tell me if IPS4 have that feature?
