Game loading options

Well, nobody spoke about it, so I assume you guys know, but when you start the game with the laucher you have some "Options" on top line of text...

With "Fast Launch" you don't have to re-click the screen when the patching is done, and I have to figure out what "Disable on-demand patching" does, is that the in-game patching stuff ? With the server being down ATM, I can't really check

Also, maybe some smart people around will find a convenient "Advanced command line" to write

On-Demand Patching was a work around the devs used to cut out around 2gb of the applications install.

Pretty much does what it says, it patches the new zones you load into, I find this more annoying than anything because the larger zones and or dungeons you have a longer load the first time.
