Really? That’s interesting cause I have a 2014 15” MBP and I’ve literally never noticed the performance difference. I find it so minimal that it is insignificant in all concerns. The improved sharpness of a integer scaling factor is the biggest draw to me of 2x scaling, but things just feel to crammed for me, so I prefer the 1680x1050 option
I have been using the default setting for at least 8 months and especially in Safari scrolling is not smooth. The old standard setting of 2x provides much sharper text, better scrolling and a smooth experience. Add to that the improved battery life too.
The caveat is of course the loss of desktop real estate, but this can be compensated in a variety of ways:
* Change the font size in Safari by using Cmd and - to adjust zoom
* Adjust zoom size in the app you are using
* Make the dock auto disappear, so that apps can use more space
* Reduce text size in preferences for side bars
* Use full screen mode when working on just one app
Of course the default setting will still give you more space to work with, but it is a shame to use it when knowing that the Macbook can display everything much sharper. It is now difficult to go back to any other setting.
I would also suggest to increase the available resolution when is really required, when you need to work with more space. For my kind of work this happens rarely..
I would like to see Apple increasing the native resolution of the display, so that we can use 1650x1050 with 2x scaling..
