Hi all, i own a Retina macbook pro (Model in my signature) OSX 10.9.2 It seems to me that when i do my work using the HiDPI resolutions in the Retina Macbook Pro, i cannot use my notebook very well, as it lags in scaled resolutions. I do heavy Photoshop CS6 13.0.6 editing and image proofing/management using Lightroom 5.3 (Studio Photography, Commercial and Event Photography) (Heavy photoshop retouching and composition making) (Usage of Text,Brush,Blur tools in Photoshop CS6 are laggy) +Also video editing with final cut pro x 10.1.1. Among the scaled resolution that the macbook pro gives, the performance that i can say that is usable for me is the (Best Retina) but the screen real estate is so small, by the time i use larger resolutions, performance is stated to decrease. Which it really do. I needed the real estate of 1920x1200 but as stated, performance is drastically decreased. I tried the 3rd party app SwitchresX, i used the non-HiDPI mode of the 1920x1200, and yes the performance surely does improve but the app limits the retina viewing. I've tried 2048x1280 But i am not sure if this is as close enough to retina sharpness with performance not being lost. May i ask kindly on what settings you guys use in SwitchresX without sacrificing much sharpness (screen blur/fuzziness) but also gives you enough performance? Thank you.
