For those who want to explore! I've been running this for three days now and I've never had FSX run as smooth as this thing does - with all sliders maxed.
This is an enhanced version of FSX developed by Lockheed Martin to better utilize the resources of today's processors.
You can run it without tampering with your current FSX - it is completely separate (I have it on a separate disk but that's not necessary).
Beware - it costs $10 per month - you can always just cancel it to quit.
Does not have all the bells and whistles - yet. But what is there is working super for me - i7-920 at 3.9ghz 6gb RAM GEForce 460.
Most Add-ons seem to work but may have to be installed manually. So far I am running UTX, GEX, Active Sky, ORBX PNW Demo, several Aerosoft sceneies, Carenado planes with no problems. I have no payware jets installed yet-they are still working on FSUIPC compatibility.
Some stuff just does not work yet, like the ACARS, Flight Sim Commander, and add-ons that look for running instances of FSX to work/connect - but many fixes are in the works.I got PlanG to work.
Website is at

There is a lot of buzz going on about this as being the future, especially if MS Flight does not pan out as a replacement for FSX.
All I know is that I'm loving it so far.
Anyone else trying it? Please post and let me know.
