The Verlet scheme supports free energy calculation in 5.0; it works
with GPUs too, but not in double precision.
However, I suggest you consider first whether you really *need* double
precision. If you do, it may still be beneficial for you to use the
Verlet scheme in 5.0 -- especially if you have a small system that
you'll run single-node case in which you can use OpenMP-only and avoid
DD and related bottlenecks like imbalance.
