Cura running very slow on my PC

[nathanswood 0]

HELP!!!  I am Running Windows 10 on an Intel Core i7-4790 @ 3.60GHz.  16 GB Ram, with NVIDIA Quadro K2200.  I have used Cura for the last several years and the last several updates have gotten progressively slower in actual functionality.  It can take half an hour to set up a simple print, where I used to be able to do it in a minute or two.  Cura spends a lot of time "Not Responding", thinking or ignoring requests.  Resizing and reorienting is a nightmare.  Changing any settings is next to impossible.  Cura is super fast on my MacBook Air, that actually has less Ram and a lower quality Graphics Card.  I have Deleted all old AppData, and tried reinstalling multiple times.   There have been no updates or changes to my machine that I know of  I can't recall the last time that Cura ran in a way that didn't waste my time, and this is a huge shame, because I absolutely hate using Simplify 3D.  Please Help Me.
