Fix to particular FPS

I need fix FPS
I making 3d Infinity Runner Platformer Game I need particular fps on play,
my laptop when charging 120fps, without-charing 60fps
I need 60fps if i charging or not, I desighn my level Map on 60fps without charging when the fps increase i had problem because level dismaintain the player speed affect Level actors & object position will not set
Example : when player jump on moving platform, player jump ahead from platform And player fall down, not set particularl

Have a look here:


when the fps increase i had problem
because level dismaintain the player
speed affect Level actors & object
position will not set

That’s because of frame delta. Some good reading:

And here:

If you start using it correctly, the game will run with the same speed regardless of the fps.

thankyou very Much It’s Work
UE4>>Project Setting>> General Setting>>Used Fixed Frame Rate

The FPS will be different on all platforms, you have to compensate for that ( see above, delta time ).
