I get massive stuttering whenever I see other planes either green or red. Its very annoying and makes the game unplayable. 

 This has started just recently though I'm not sure i get a decent ping but the stuttering coincides with a variance spike on the AH net status clipboard. 
I have fast internet, and a decent rig. Its very confusing.
