Hey folks, If there is already a page for this, then I apologize. I know there are lots of threads complaining about scrolling lag and for a brief period I had late 2013 13" rmbp, but returned it in the 2 week window because I needed a bigger screen. While the 13" only had the traditional iris, it did seem to be slow especially when manipulating websites that were already loaded OR even pdfs. Since I did not know of this Quartz Debug for testing fps in Mac when I had the laptop and I'm not too sure apple's policy on installing it on the demo computers, I was wondering if someone might be able to run Quartz Debug (specifying the specs of your computer & which resolutions you tried) and post your results? I'm looking for Min/Max/Averages, in a somewhat similar fashion to: http://www.anandtech.com/show/6495/...erformance-on-macbook-pro-with-retina-display Is the "UI" lag only when the page first loads or consistently? People say there is no lag in the Iris Pro, but can anyone confirm this with some numbers? Much appreciated.
