Its just one of those things i cant stand, it affects me on xbox one games that have low FPS aswell, it annoys the crap out of me. Ill be replacing my 2011 MBA with a 2015 MBA, i would love a hi res screen but that ui lag is unbearable and for the price Apple charge i want perfection.
You guys must have super eyesight I guess. I do photo and video professionally and I can easily notice when video is dropping frames I don't see any lag at all, odd. I'll still post a video so others can see for themselves
