There are currently rifts in the Force that are causing Vader's Force abilities to fluctuate wildly(it was a whole thing in the comics)... Though I suspect that will all get resolved before we're properly caught up to RotJ.
Aside from that, there is really no evidence to suggest that Vader's power has done anything but increase since ANH/ESB. Inner conflict 'hindering' him(or w/e) isn't a thing at all right now -- quite the opposite, actually. Of course, that can all change with a single issue... But as of now, I'm comfortable saying that current Vader > ESB Vader > ANH/Rebels Vader, and so on.

Not opening for me. Where has fight happened? And when does it take place?
In recent Darth Vader issue. It seems Vader has studied and thus gained the knowledge how to make Scourge of the droids.
He also is able to use Force through those infected machines
