i thought rolling back to VP (5-20-3) eliminated the problem, but after an hour of gameplay, it becomes a problem again. i even rolled back the video driver to no effect.
the latest version of VP changed something, somewhere, but i cannot figure out what. i have stopped short of reinstalling CIV 5, since that would take so long.
I have not had any such problems, although in the latest version - it happened only a couple of times - a unit slowed down a tiny bit when moving from point A to point B. I think if other people were having the same problem as you, the forum and GitHub would have already been flooded with reports. As you say that the same problem - only to a lesser extent - appears even if you downgrade, it seems to me that there is something wrong with your computer/system/install and something in the new VP is maybe amplifying it somehow? I do not mean to scare you, but Civ5+VP was lagging badly for me on my old computer when my hard-drive was dying (you would not like to hear the screeching sound it made before it left me for good!). Did anything change with your computer lately? New video drivers (you say you rolled back?). I would give reinstalling Civ5 a go - it is not as bad as it sounds (unless you are on some very slow internet connection).
