I have tried this software in Preapar3d V2.3 with the latest Nivida update (344.11).  VC still is unable to break the 20fps mark, even with very sparse settings.  My advice, is pass on this one.

Is the iFly mentioned in the tests the 321 FSX or P3D version from Flight1tech?

Both versions when running under P3D seem to be limited fps-wise on certain machines. I can't speak for all. I know there are a few PMDG P3D flyers, but I have not seen them mention a fps lock so not sure what performance they are getting, but on my rig both are fps locked in the twenties when compared to FSX.
