UI / Scrolling Lag
Hello,
I bought the mid 2014 ( 15inch Retina, 2.2 GHz Quad Core, 16 GB Ram, Intel Iris Pro, OSX Yosemite 10.10.2 ) yesterday and I am experiencing UI Lag and Heavy Scrolling Lag on bigger pictures 3648 x 2736 pixels ( http://upload.wikimedia.org/wikipedia/commons/9/92/Big_Sur_Coast_California.JPG ) , while the mac book air next to me (13 inch , mid 2012) is experiencing no lag at all.
It happens to me on 1440 x 900 Retina, 1680 x 1050 Retina and 1920 x 1200 Retina resolution. After alot of frustration and research an app called "Display Menu" which allowed me to even use high resolutions as 2880 x 1800 in non Retina Mode and I had literally no lag at all.
Now to my following questions:
1) Is the technology not capable of handling these kind of retina resolutions?
2) Is my mac book "damaged"?
3) Will future update of Yosemite fix this kind of issues?
I am really not picky about lags or little issues that will be flattened out, but as someone that works in the webdesign / printdesign field i cannot use this mac book productive.
Thanks for reading and a constructive feedback
MacBook Pro with Retina display, OS X Yosemite (10.10.2)
