I know this isn't the ideal setup, but I can't really afford much more, and it almost works. The problem is when playing a video I recorded with Playon (mp4) from Gsuite on GFS I can't get it to cache enough so that it will play smoothly for more than a few minutes. I tried Rclone, but got the same behavior. I am not sure I got the config for rclone right. (mount --allow-other --dir-cache-time 72h --drive-chunk-size 64M --log-level INFO --vfs-read-chunk-size 32M --vfs-read-chunk-size-limit off gdrive: X: --config "C:\Users\Matt.config\rclone\rclone.conf" --vfs-cache-mode writes)
So theoretically if you get more than 3.6 Mbit/s speed on average it should work.
But first you should make some speedtests to see what speed you actually get.
Then, Videos don't have a constant bitrate. So slow scenes will use less than 3.6 Mbit/s, but scenes with much action will use more (and this can be much more). Try to increase the buffering in your player so it buffers much more. I'd try to set the buffer to a few minutes and try that.
