Do you mind trying RadeonPro to force v-sync, triple buffering or, even better, force limit your framerate to your average fps that you get in-game ?
You may have to create a game profile for each game, but if you get it right, you won't regret it.
Just a suggestion that works for me as well.
EDIT: "Keep crossfire disabled or lower in-game settings."
yes, that was not helpful at all wasn't it now ?
