For about the past month I've been having serious buffering issues in Chrome with YouTube. Used to load 720/1080p content with no problem. Now it fumbles along so bad I have to drop down to 360/240. Deleted history/cookies/logins from Chrome, but no dice. Would Adblock be causing the problem? Here's my specs and Speedtest...
