U guys are awesome 
Just wanted to give a heads up on my experience:
I was having a similar issue where all 32 Gigs of my RAM got eaten up after launching the editor and couldn’t be resolved with anything but a reboot. I was using display Fusion (multi-monitor manager) and didn’t have the latest GeForce drivers. I removed display fusion and updated drivers and it has seemed to have fixed my problem. Not sure why, but relieved.
