I stand by my post without question. FSX is not a multi-threaded application.
And I challenge the Aces team to prove, fully, that it is... when they themselves have only said "at run time, we'll take one core to load textures, and another core to "load other things". That is great, if you edit the *.ini and tell the software which core to use for which task.
I'm fine with my stance. I stand by it.
