I got selected at the end of July to participate in the "closed beta". My system motherboard is a 7 year old ASUS Z87 with an i7-4790K processor and 32gig of RAM. With the Corsair water cooling system on the processor I can overclock the processor to 4.7Ghz. Video card is only a couple years old .... GEForce 1080GTX 8gig EVGA card.
I was surprised that it ran the sim pretty smoothly between the mid and ULTRA settings even with the 3 monitor 5850x1200 resolution. However, I can foresee an upgrade to get it where it needs to be. I was gone to Boston last week to visit my son and his family and to meet my new granddaughter who was born July 7th. When we returned the Beta had expired with the official release on Aug 18th. After about 4 days of hem hawing around, I pulled the trigger and purchased it Saturday. Having been around flight simulation since the first issue by Sublogic I figured why stop now.

Since am no longer bound to the beta Non-disclosure Agreement, here are some 1st impressions:
- A good internet connection will be needed ... initial install is a little over 95 gigs.
- Installs thru the Microsoft Store as an app, so you will need a Microsoft Live account. Install is a little clunky. It popped up a window and said it could not find a "registered device" to install on with the only button being cancel. Hit that and it goes back to the Microsoft Store and indicates it is installed. Saw some forum posts later that indicated their is an option to install in a custom location which might be something to look at. The default install puts files in unusual locations ... ie %appdata%
- Took me 4 hours to unmap the controls the program guessed I would use with my controllers and to find / map the ones I needed for basic functionality.
- There is no built in screenshot key at the moment ... so the Windows Key + Print Screen key will save a shot to your pictures folder.
- Pete Dowson has released a beta version of FSUIPC7 that runs as a separate exe .... not an embedded dll within the sim. I tested it and found the same issues others in the MSFS forums found .... it turns the sim into a slide show. From the forum posts I've read, seems the SDK that developers need is not complete. There was also a reference to an update on Aug 27th that might fix it.
- This last one is an assumption on my part in which I hope is totally incorrect. I don't think you will see the "freeware" options that were with the FS9/FSX/P3d products. The program menu has a "store" function in it .... presumably for installing aircraft , scenery, and add ons. It gives me the impression that they have adopted the Apple model of requiring everything to be run thru their store. Maybe how their business model expects to generate revenue ... taking a cut from everybody who develops something for the product ... (again conjuncture on my part). Liveries maybe different, as there is a site:
https://www.msfsaddons.org/ that is offering liveries and the convoluted method of installing them. Right now there are only 3 jet airliners .... A320, 747-8i, 787-10
