The new Google Drive client is horrible with lots of files. It is doing something very wrong in its sqlite database and completely killing performance of the drive where AppData lives, even if the Google drive folder is on a different disk.
can confirm this exact behaviour. its supposed to do intelligent caching/streaming but as mentioned in parent, my DriveFS %APPDATA% filled up with hundreds of GB of temp files. had to uninstall, deltree, reinstall to fix. bit of a pain.
