I'm wondering if any of you are noticing some lag in the 3D window in 2014. I found the 3D window viewing and scrolling in 2012 much better. In 2014 there seems to be a delay in the 3D zoom, and also when viewing the model it is constantly regenerating. In 2012 it regened once and then I could rotate and move around the model with no delays. Any ideas as to why this is?
