My frame rate never go down from 120

I updated 4.10 recently, but as the frame rate range set to 22~62, it never changes and remains 120,
If I choose the Fixed Frame Rate(30 for example), the whole system seems speed up several times…and the rate is even larger than 120

What should I do?

New finding:
I tried typing “t.maxfps 60.0” in the console, it works! Frame rate is locked to 60.00

But I still wonder if this is the right way to achieve the goal, as the smooth function seems being abandoned. Is there any bug around this part of editor?

HI SpiritJZL,

Using the console command should be fine.

As for Frame Rate Smoothing Eric does a good job of explaining this in this AnswerHub post: https://answers.unrealengine.com/questions/90743/what-exactly-does-smooth-frame-rate-do.html

Thank you!
