Okay, after pulling my hair out for the past few weeks, I've finally figured out what was causing my stutters/micro freezes. It wasn't Windows, DX11, background processes, or driver issues...

It was..... <drumroll>
Checking 'disable players skins' in my AH3 Graphics Options!!!!-and-
Disabling Skin Downloads in flight 
If I had read the hints and tips at the top earlier, I could have avoided this issue. This should be sticky in its own category for everyone to see. I guarantee this will work for a huge chunk of the players experiencing micro-stutters/freezes.
