In case people are looking for a Google Drive client that feels pretty well put together, I'd recommend Overgrive: https://www.thefanclub.co.za/overgrive
No idea, but Overgrive feels as fast on Linux as the Google Drive client on OS X does for me. Its also 5x cheaper, although the site is decidedly less professional (which actually comforts me in a strange way because that means its probably made by a Linux geek who cares jack shit about fancy UI = good core code)
