But I must ask you; Have you considered posting it on the http://www.fsdreamteam.com/ main page?
There are links for the Addon Manager stand-alone installer on both Zurich and O'hare produt pages.
Also, what does the "View Optimization" check box do?
We were running an internal betting about who might be the first user that noticed that...
It's an experimental feature that, being experimental, is disabled by default. If you enable it, the Addon Manager will determine your actual view direction, and will throw away entirely 3d objects that are in a "blind zone" behind the user. The object is not simply culled from display, because FSX does it anyway, but it's destroyed altogether.
This option might help the frame rate, of course only in sceneries handled by the Addon Manager (Zurich, O'Hare and the upcoming JFK). My estimate is that the more powerful your system is, the less the option is effective, but it's a wild guess. You *might* also notice more stuttering with the option on.
We are interested hearing some feedback: you can simply enable the option, and immediately see the results, there's no need to restart FSX or reload the scenery. If the option is off, it will works exactly like it always had.
