I am also quite happy with it. I installed it two days ago, and yesterday I set up all my ORBX regions and all my Norwegian scenery, in addition to 737NGX, C337, and several other aeroplanes. I'm also running EZDOK with TrackIR, ActiveSky, PlanG (EFB doesn't work), squawkbox.
I had my first flight on vatsim yesterday, from ENGM to ENVA, and I must say it was a very smooth experience. It tackled much more clouds than FSX using more or less the same settings for the rest of the scenery and I was looked at 30 FPS the entire flight. Usually drops below this to 20 (or even lower in heavy clouds).
All in all I am very happy, and I will probably not be using FSX that much anymore. One of the few remaining obstacles is FSX multiplayer...
