So I start up the game, with in game overlay disabled, playback disabled,twitch disabled EVERYTHING DISABLED... And I come back to my desktop and I'm spammed by low disk space errors... Please fix this.
The warning is placed there for a reason, and generally being that low on disk space can be dangerous, especially on a boot drive (If that is your boot drive). It doesn't appear like it's using very much space (perhaps in the 10's of MB) which that can be altered with temporary files or logs. I'm sure you understand that this issue will disappear if space is cleared up on your drive.
I will bring this up with our team to see if we can't get around the amount of messages it shows.
