Tried downlord's client again after a few months.

Everything seems to be working nicely and without stutter. Only a couple games in it seems that there is less ui lag. Perhaps because it doesn't force FA to wait for it as much as FAF does, while sending packets back and forth. Completely non scientific placebo, double blinded wishful thinking conclusion.
