Configuration: Smoke Simulation at 60FPS

I want to render a smoke simulation at 60 fps, the problem is it doesn’t. At first I backed my smoke simulation and then the particles with the Smoke Flow Force Field. (both from frame 1 to 250)

They should go with the smoke and surround it.

When before rendering I set the framerate to 60fps and set the time mapping to (old: 24 new:60). I also the endframe to 625.

After rendering for 12 hours, I noticed it didn’t work exactly as I wanted. The particles move till the end but the smoke ends at frame 250 and freezes. Although both simulations were backed at 250 frames they were in sync in the render. I dont really know what happens. I would say, the render doesn’t seem 60fps but there aren’t really any reallife physics in it so I cant tell. Maybe the time remapping won’t get applied to the smoke, at least thats what it looks like.

Its blender 2.79b because the smoke flow force field is glitching in newer versions. Please be patient if my question isn’t complete and lacks quality, this is my 4th try, rendering this and its 2 am.
