Longtime Sketchup user here.
Im getting a sluggish SU viewport framerate (10-20 fps) on a new macbook air, regardless of model complexity and even on empty projects. Using the same machine with bootcamp/windows, the camera is butter smooth.
I use OS X Yosemite on a 2014 macbook air (1.4 ghz, 8gb ram, hd5000, 256gb ssd) and have tried SU 2014 and 2015. Ive reinstalled and enabled/disabled hardware acceleration but no luck. Strangely, when I make the SU window really small, the framerate seems to go up.
Anyone else having this problem? Is this known? What might the issue be?
Thank you & all the best
