No. You don't have to have everything. I use two installations linked where one simply runs the visuals and the other displays a VC view of the instrument panel. The VC/instrument computer has default scenery and all fancy graphics options dialed down.

Hmm. OK. I'm actually a Prepar3d user who never bought or used FSX. I might have some issues...

Is there a PC-12 that works fully under Prepar3d? Has anyone tried the Flight1 or other FSX aircraft to see if everything functions correctly? Thanks!

I've been using Prepar3d on a clean windows 8 system with no other flight sim. I've had a few issues that I believe were mostly related to how it was installed. I strongly advise running the Prepar3d setup program in Administrator mode and then going back into the Lockheed Martin/Prepar3d/ directory tree structure and setting the file permissions to Full Control. Then, I also recommend running the Program in Admin Mode during normal use. Seems to help avoid some of the problems others reported.
