In my experience 30 FPS is perfectly fine for a game like this, I'm not sure what do you mean about "scrolling" ?
It's the much more fast paced, mostly first person games that really need those 60+ FPS...
Considering something like Simcity 2000/3000. Visual update is probably in single digits FPS most of the time, but the input cursor is very smooth.
A top down city sim 'scrolls' up/down/left/right around a map, which is a movement that is strongly associated to screen tearing -- which i'm not really sure is a relevant thing to bring up given the variety of v-sync options available.
Even a game locked at 30fps that 'scrolls' often shouldn't experience significant tearing with the options out there.
