1) Wondering what resolution you are running day to day? Best for Retina is too big and the 1440x900 seems a little blurry to me. 2) Have you turned off font smoothing? I turned off font smoothing which helped with the blurriness a little but also make the fonts look a little washed out. 3) Notice any UI lag difference between resolutions? I didn't notice any difference going from Best for retina to 1440X900.
