Short description of error
['Use Adaptive Time Steps' setting in the Domain settings only seems to change when the minimum value is raised, as in it does not seem to 'adapt' between the set minimum and maximum values entered.]
Exact steps for others to reproduce the error
[Bake the attached blend with 'Use Adaptive Time Steps' disabled, then again with it enabled and set to minimum=1, maximum=8, it will look the same, with visible steps in the smoke/fire trail every frame, then bake again with 'Use Adaptive Time Steps' minimum increased to 2, you should see the 2 steps in the smoke every frame.
Then again with the minimum set to 3, looks useable by then, and not much different from using a minimum of 4 for this sim.
It looks like this-
And here's the blend-
So it looks to me like the solver is not 'adapting' much, definitely not in this instance anyway.]
[Based on the default startup or an attached .blend file (as simple as possible)]
