Ever since the latest update to the Bethesda/ZOS Launcher (on Steam), the launcher itself uses an extremely high level of I/O with a constant activity of 20-50 MB/s on Read channels and 10-25 MB/s on Write channels. And I mean *constantly*; it never settles down.
I can't help but assume that this is precisely why the game itself (eso64.exe) fails to properly load half the time.
Seriously, WTF is going on with the launcher? There is *no* justifiable reason for this.
