I have been reading about AffinityMask in other treads. Lots of folks seem to know what it is and what it does and how it works.I looked through the SDK materials and can't find reference to it yet I suspect that it must be in there somewhere.I am confused about this command and really would like it if someone could explain what it is and how it works AND most of all, exactly where does it go in the fsx.cfg file?AffinityMask=??I have an AMD Athlon 64 X2 Dual Core machine, what command would I use and where do I place the command line?

Look here:http://blogs.msdn.com/ptaylor/default.aspx[JOBSCHEDULER]AffinityMask=nwheren=1 for 1 core n=3 for 2 cores n=15 for 4 cores

Perfect!! Thats what the Dr. ordered, medicine for my fs ills maybe.
